Don't know anyone like me, for every day in the use of toshiba satellite l775d s7222 laptop keyboard keyboard and mouse with a set of the standard of the choice, there was a temporary need a keyboard, in a hurry to guanghua market bought one of the most simple keyboard, originally want to say 101 standard keyboard performance should be about the same, take back to the company that connected to the computer, use the no 10 minutes I was thrown into the trash can the.
Most of the time now is the use of NB, but meet use not smooth, always external keyboard to use. For example, wish to use the 22 inches big screen, or as my ThinkPad X60s Plamset will have enthusiasm, this time can use external keyboard let your work environment comfortable.
Originally the most like the keyboard is the traditional mechanical 101 key keyboard, but now only Benq production and [Insert], [Delete], [Home], [End], [Page Up], [Page Down] and so on six key has not standard arrangement, use rise often in the wrong key (habit was terrible). I later found out that IBM has a paragraph Ultra Nav keyboard, IBM's keyboard is very famous, and including everyone take delight in toshiba satellite l775d s7206 laptop keyboard
talking about little red dot TrackPoint. In the foregoing I into the trash can keyboard, went to buy a contain digital key Ultra Nav to use, then in order to save space (in fact is own desktop mess) and carry convenience, buy again without digital key Ultra Nav in office use.
Some colleagues smile how do I spend so much money on the keyboard mouse above. But they don't know something, if the keyboard playing up not feeling words, the program code can't write out, will express wonderful in a bad mood. Another good keyboard and mouse for long time using computer working people, is also very important, have often feel fingers/wrist joint will acid, with the typing position and use the hard, now keyboard manufacturers will many don't need to add the stunt in keyboard mouse above, such as emphasis on multimedia, etc., I occasionally see such goods ads are in want to every day, adjust volume switch no two times, and even for all fixed use headphones so don't go to adjust the volume, the volume adjustment button on the keyboard it doing? Some also install the driver program waste computer resources. How does not put toshiba satellite m305 laptop keyboard
idea on the use of comfort the above? But in order to costdown, mostly using film type keyboard.
I feel for the keyboard seems very exacting, actually otherwise, I sum up to the requirements of the keyboard only three points:
1. Knock feeling good, knock on feeling and keyboard feedback force related, on the market a lot of keyboard are using film type components, this will cause stroke are not clear.
2. Comfortable, long time using computer, the most often move to joint is? Finger joints, how to provide staff more comfortable tool, the efficiency will follow the ascension
3. Precision, typing or write programs work is the most important thing is correctness, when fingers on the keyboard in the fast flying above, and each key can be more accurate revealed is very important.
Well said so much, this to introduce today's leading role Realforce 101 the keyboard toshiba satellite m640 laptop keyboard
, the keyboard is designed by the Japanese Topre production, when I first saw his appearance let me surprised, is really very traditional 101 keyboard design, this also lets my favorite place, adopts the traditional 101 key arrangement way and key distance (each key was separated by distance). This let me to this company very curious, willing to such a bold adopts the traditional keyboard design, and not add any fancy and excess stunt
Began to try first feeling: "light", this may be because use is Torpe company respective contactless electrostatic capacitive technology patent related. I often use than the ThinkPad NB or UltraNav keyboard even haven't contact mechanical keyboard and effort, "contactless electrostatic capacitive technology" to provide feedback force very moderate, this design can let finger power more effort and to provide a comfortable operation. Now there are manufacturers are willing to work hard on the see place is really rare.
The next for long time input test, first of all let me pay attention to is not card key, because use ThinkPad NB keyboard or UltraNav keyboard or diaphragm keyboard, often meet a problem is will card key, typing fast fingers when often card to the next key, such as press "F" key then according to "T" key word, your fingers will hit the "T" the edge of the key. Because Realforce keyboard adopt standard keys particle size and key pitch design, so will not have card key problem.
Realforce there are several characteristics
1. Every single button above seems to have a "sand" (don't know that this is right or not) the treatment of, every single key surface feels thick thick, let your fingers in different between key jump, can be more clear feel "contact sense".
2. Key the above text not stick up, and now most of the toshiba satellite m645 laptop keyboard
keyboard is will letters with sticky (or spray) up, and Realforce don't know what is the use of technology, careful not to die like general keyboard there will be a great feeling.
3. Touch and simple sense is very good.
4. Weight is heavy.
5. Finally the most important, according to the arrangement of each row of the position is different, the key point of view is different, so that the user can make design type, every button in the hammer, can use the best rap point of view, in addition to increasing precision outside, still can make the user more comfortable. You can see their own use keyboard, each key of Angle granule is the same, so look from flank is flat, and each row Realforce keyboard button with the naked eye see is not the same. This is representative of how much more cost? In addition to the production of different view angles key outside, assembly time also need according to different key position installation up.
After the completion of the trial, let I even more to admire Japanese for extreme requirements, seemingly ordinary keyboard toshiba satellite p300 laptop keyboard
, but in every detail strive to perfect.
Each row of the use different radian increase comfort and accuracy

Notebook how to upgrade SSD + HDD
By bobo anthony on Monday, November 5 2012, 03:01 - laptop cpu fan
In recent years, computer hardware hp g56-151xx laptop keyboard development speed quickly, one not careful it may be often pay attention to hardware friend BS: you OUT! INTEL CPU architecture update soon, performance improvements soon, AMD CPU are also no improvement under the background of CPU architecture, through go high performance-to-price ratio and low power consumption for supporting. DDR3 memory price is already cabbage price, 07 years notebook a lot with standard is 512 m DDR2, now are 2 g DDR3 many even 4 g memory, there WIN7 and VISTA triumphant to wei, although VISTA is user scold the dog, but now it seems, for the arrival of the era of mass storage or played a very positive role, big companies and we urban petty bourgeois, their strategic vision is I can't imagine. It is a hardware and software, and mutual cooperation to dip light common people's purse is inevitable, not complaining.
But tough CPU and large capacity hp g56-200tu laptop keyboard memory plus hundreds of G hard didn't let us feel the computer real fast many, only can WIN7 just normal operation. And speed powerful SSD hard disk of a large number of shop goods indicates that it is likely to replace HHD, become system partition's pet. The speed of SSD hard disk relative to the mechanical hard disk is spotless, and, of course, other N many advantages, such as small white I also know: speed is much faster than mechanical drive, which is the boot speed; Mute. Of course, now SSD hard disk capacity is still too small, and the price is relatively expensive, if only to buy a piece of SSD hard disk to install system and store data of words, may be luxury some.
I think from hp g56 laptop keyboard the current market opinion, notebook stored a trend should be: take off cd-rom, instead of SSD and HDD double hard disk, high performance as the SSD system partition, and large capacity of HDD as data access partition. Memory keep now of 2 g - 4 g, family normal use is no problem. Notebook drive now very chicken ribs, its action was:
(1) installation system. But cd-rom installation system is a big noise, and read data slow, gradually has been mature WIIN PE installation system to replace.
(2) the burn data. Burn data performance-to-price ratio is not high, I also have a desktop, desktop also installed the CD writer, but always feel are not useful at all, my experimental data is also a few G, notebook and desktop inside each backup a, then U disk backup a copy of all three parts, has no risk at all. Love action movie is everybody must storage, buy a 500 g mobile hard disk is enough, or not timing update, more bang for the buck. So burn data I think also pretty of chicken ribs.
(3) read CD data. This may be the only really difficult to replace, but I would like to say can use desktop hp g61-100ea laptop keyboard
cd-rom to copy, and then directly through the router direct transmission to the notebook hard disk well inside. So read CD data can be well solved.

Teach you four recruit easily get Windows system optimization
By bobo anthony on Monday, October 15 2012, 08:38 - laptop cpu fan
A, what you need to do optimization
System after download and install where need optimization? First the rookie to Chou Chou, so in XPy in setting optimization options will have targeted the.
1. The page file system optimization
2. System start menu popup speed too slow, icon cache is too small, need to adjust.
3. The ibm lenovo thinkpad t61 7665 laptop cpu cooling fan default launched some independent service, has nothing to do with port may be safe hidden trouble.
4. Some application after installation will self-assertion in the start menu since the launch of the program to add the corresponding items (such as installation Office after some input method entries appear in the automatic item).
5. System can not be automatically according to your network link mode set different maximum transmission unit equivalent; IE and connection number is too small.
6. The system default installation Microsoft offer of some software, don't need can be removed completely.
7. Software uninstall not completely,ibm lenovo thinkpad t61 8889 laptop cpu cooling fan the system still have residual files or registry key.
Second, the quick setup XPy
First start XPy, in the "Settings" (set) window choose the type of optimization, simply from the drop-down list can choose scheme. XPy besides contains "No Settings" (don't change system original Settings) outside, optimization Settings combination also contains the following modes, and every kind of mode have good match for you the related items:
"XP Antispy Settings" : anti-spyware program setting. Which can improve the ability to prevent malicious software (for Windows XP effective).
"All possible setting (Auto Detection)" : automatically detects All possible needs to adjust the project, the proposal USES.
"All Settings" : All optimization, automatically in XPy will provide optimization option All selected and applied into the system.
"Custom" : completely by the user ibm lenovo thinkpad t61 8891 laptop cpu cooling fan choose our need to set up entries, but there are some difficulty for beginners.
O sprout tip: generally don't choose "No Settings" and "All Settings," the former not optimization, while the latter may optimize excessive lead to new problems. Try to choose customizable set.
According to the different choice models still need to affirm, then click "Apply" button, in the next "Installing" dialog box, the software will be the home on the system provide necessary modifications, click the "Show Details" button to view Details. Then ask if restart to complete the final modification, restart your system will be selected according to the model optimization.
Three, system Settings, give me the right to know
XPy can also let users have to set up the system of right to know - when the mode choice, in the list, you can detailed view each mode changed exactly what project.
For example, choose "XP Antispy Settings"ibm lenovo thinkpad t61 8895 laptop cpu cooling fan item, you will find it only chooses the "General" (conventional), "Services" (Services), "Internet Explorer" (IE browser), "Windows Media Player" (Media Player), "Windows Messenger" this several, it only for these entries of small projects to carry on the revision, and spread the corresponding items, you can better understand XPy exactly what to change.
For example, in "XP Antispy Settings" (anti-spyware software pattern) expansion "Internet Explorer", we find it only in the following Settings: "Disable Automatic Updates" (prohibit Automatic Updates), Rename UPLDDRVINFO HTM. "(will UPLDDRVINFO. HTM file renaming), UPLDDRVINFO. HTM file is" Windows XP HCP URI can be directly deleting files loopholes "may be used in a document, because the browser submitted HCP URI request existing safety problems, therefore has the hackers will use the file of the ActiveX control to delete local files, this belongs to the dangerous file, affected system including Windows XP home edition and professional edition, many security experts have suggested directly deleted, and XPy approach is to name it. If you want to under this model are fixed more ibm lenovo thinkpad t61 8897 laptop cpu cooling fan depth system Settings, completely available checked.
O sprout tip: through this detailed Settings, you can completely will system optimization Settings control on palm, understand exactly what the project is modified. The comparable one by one into the system registry or service manager and other Settings much more convenient to use.
Four, give you an undo key, sorry, don't worry optimization excessive
If you graph save trouble and dark chose "All Settings", ibm lenovo thinkpad t61 8898 laptop cpu cooling fan in the discovery after restart the system operation anomaly also need not nervous, and many system set up different is, XPy provides "regret medicine", you can easily modify the previous reduction set to (a lot of software just optimization, does not give you the optimization of the right to know, let alone make you Restore previous set up), particular way is rerun XPy, in tip picture click the "Restore" button, and then click "Apply" button can return to its original state.
This mechanism, you don't have to worry about system is "optimization excessive", once the system has any exception, you can quickly restore previous state. When you play in new system after the patch, use the system to do some XPy set-up, no doubt will be ibm lenovo thinkpad t61p laptop cpu cooling fan quite convenient, and the optimization effect is also very obvious.

1, market at present fashion hp pavilion dv4 series laptop cpu fan transit micro camera driver version many, many users in the installation and unloading drive process residues have junk files in the system registry inside, cause behind the driver update process installation difficulties;
2 on market at present, there exists a kind of cloning operating system, which integrated the transit micro and the old with WHQL drive, when the user install new buy cameras or update the latest drivers, the camera doesn't work;
Methods a, automatic unloading method
Step one, click on the start menu corresponding driven Uninstall unloading, (possible Uninstall functions has been destroyed, so can by installing new drive for counter installed, the system will first will old drivers unload off, also can achieve.
Step two, in the new drive before hp pavilion dv3 series laptop cpu faninstallation choice attached below the corresponding executable file:

By bobo anthony on Tuesday, September 4 2012, 03:44 - laptop cpu fan
Fault a: memory bank and motherboard slot bad contact, memory controller failure performance: open after the power supply of main screen shows "Error: Unable to ControlA20 Line" Error information system halted.
Means of settlement: carefully check whether the memory and slot to maintain good contact or replace memory bank.
Fault 2: self through. In the DOS state run applications for occupied Memory address conflict,dell studio 1535 series laptop cpu cooling fan and cause Memory allocation mistake, screen appears "Memory A11ocationError" clew.
Means of settlement: for Confis. Sys files use Himem. Sys, Emm386. Exe file Settings, such as Memory management Xms. Ems Memory or Settings, making the system can only use 640 KB basic Memory, the running program will appear larger "Out of Memory" (Memory) suggest that cannot operation. These phenomena belong to the soft failure, write good system configuration file config.sys after can restart your system.
Fault 3: Windows system applications running illegal access memory,dell studio 1537 series laptop cpu cooling fan memory resident too many applications, active window open too much, application related configuration file is not reasonable and other reasons all can lead to screen appears many relevant memory error information.
Means of settlement: such fault must use clear memory-resident program, reduce the active window, adjust the configuration file (INI), reshipment system and the application procedure of way to deal with.
Fault 4: Windows system operation DOS state of the application software (such as DOS run game software, etc.), because between software distribution, to use memory conflicts blank screen, flowers screen, crash phenomenon.
Solution: exit Windows system, into the DOS state, and then run applications.
Fault 5: the procedure has the virus, the dell studio 1555 series laptop cpu cooling fan virus program memory-resident, CMOS parameters in the size of the memory value by virus modification, will cause the memory value and memory bank actual memory size discrepancy, memory work abnormal wait for a phenomenon.
Solution: the antivirus software to eliminate virus; CMOS parameters in modified by the virus, the first CMOS nipple discharge, rebooting the machine, after careful examination into the CMOS various hardware parameters, properly set about memory parameter value.
Fault 6: computer upgrades for memory expansion, chose and motherboard incompatible memory bank.
Means of settlement: first upgrade motherboard BIOS,dell studio 1736 laptop cpu cooling fan see if you can solve the problem, if still no use, had to change the memory bank.

Windows 7 operating system memory occupancy big reason analysis
By bobo anthony on Friday, August 31 2012, 03:30 - laptop keyboard
Superfetch and is not a new technology, in vista age will have toshiba satellite a205 laptop keyboard started to use, but in view of the number of vista used less, but XP era of all kinds of computer skills always also thorough popular feeling, so a lot of people are in doubt why windows7 memory occupancy so big.
Superfetch memory management mechanism will users may use application page using memory space available for preload; As far as possible, avoid system occurs from hard disk page call; Let the application the fastest speed open; Not because of the computer for a long time and make use of idle suddenly become slow response, In the exit large application will be active to forced to transfer to the virtual memory before the page of memory to call. This seems to be a little to look professional, so then look down, and I will be very good for these characteristics of understanding.
Why first start-up procedure will feel very slow?
Believe that everyone had the similar experience. When I after startup, the toshiba satellite a205 series laptop keyboard first run a program, they say Word it, may need to 5 seconds to start. When I shut down after the open, perhaps for 2 seconds. If I don't close, directly open another Word documents, then the faster.
This is what reason is caused?
When we after startup, working set there is no Word the employees (page), he also at home (hard disk) inside. So when I call him, it from home to office (working set). This process is called do hard paging, of course need a long time. And when we close the Word, he was sent to the building's another room, but I again immediately call him, at this time, another room data has not been clear, he is not coming from home, but directly from data structure in the introduction. In not close the program under the condition of the Word, he doesn't need to make way for other applications, it also exists in office (working set) surface, summon him will be faster. This need not from toshiba satellite a205 s5801 laptop keyboard the hard drive to call in the data, but the data structure of the page to mount to work centralized process, it is called soft pages. Everyone knows that memory speed far more quickly than in hard disk, so soft paging use is the second operation procedure become quickly reason.
Windows 7 memory occupancy reasons
Now we know that when memory is need to program page can make the program startup faster and faster. And the Windows 7 Superfetch has the function of learning, since the first time use Windows 7, Superfetch began to record our usage, we often use the program page in the boot after loading in advance, then when we first open the program can get like the second open the same speed. So the preloading page will make our memory occupancy to grow. Say simply is to make all program operation in memory, avoid using hard disk hard paging space, this is what feeling for Windows and take up the cause of the great memory.
Check preloading memory
And in XP era, maybe you have also had the similar experience: when started toshiba satellite a205 s5803 laptop keyboard to use some of the program, because something left. Back when it found the system response is very slow, especially bad. This is because the XP memory management mode efficiency is very low.
When we left, and the program are in do not use state. At this moment the system some background program, such as disk sorting, antivirus software program will run at full speed, cause we use of some of the procedures page had to be pushed into a hard disk virtual memory. But when these background program after completion of a mission, XP system will not be pushed into before the virtual memory page guide back to memory. Then again in using computer, the system will helter skelter on temporary regulations, and even hard paging. Lead to program response extremely slow. So it looks XP free memory a lot of, in fact, didn't have any too big effect.
Windows 7 use advice
Anyone hope that through the optimization means let own computer speed to achieve the most ideal state, and memory effect is computer speed very important factors, we learned about the Windows 7 memory management mechanism, and then introduce what method can give system accelerated.
1, use more dormancy and sleep
SuperFetch due to the boot after preloading, so I suggest you do not shutdown. Try toshiba satellite a205 s5804 laptop keyboard to use dormancy or sleep, so the SuperFetch preload content will be retained. To improve the speed and efficiency.
2, use ReadyBoost
Many users from XP rose due to the system memory is not big enough, so I can't fully play the function of the SuperFetch. We can use ReadyBoost function to help us solve this difficult problem.
As long as meet the conditions of the usb flash disk can accelerate our system. toshiba satellite a205 s5805 laptop keyboard ReadyBoost function is the use of usb flash disk capacity as SuperFetch preload page storage space. But because of the special micro soft algorithm, so will not affect the life of the flash. And, for the best ReadyBoost flash for physical memory size 1 ~ 2.5 times. If the system of physical memory is large enough, there is no need to use the ReadyBoost. Right click the U disk plate operator choose attribute, switch to readyboost column, speed up to the standard of the U disk can open this function.
Not all U disk can use
Through the SuperFetch understanding, hope more friends come into use windows7 toshiba satellite a205 s5821 laptop keyboard team. In fact the same for the Windows, different and where? Not accustomed to also is temporary. After all, after a Vista of temper, Windows 7 will become more mature!

How to fix the hard disk partition table and zero track
By bobo anthony on Thursday, August 30 2012, 04:36 - laptop keyboard
Zero track in hard disk on a very important position, hard disk master compaq presario a903tu laptop keyboard boot record (MBR) area in this position. MBR is located in hard disk 0 track 0 cylindrical 1 sector, including storage of a hard disk master boot program and hard disk partition table. In a total of 512 bytes of hard disk master boot record sector, 446 byte belongs to hard disk master boot program, 64 byte belongs to hard disk partition table (DPT), two bytes (55 aa) belong to partition end mark. Thus it can be seen, zero track once damaged, will make the hard disk master boot program and partition table information to suffer serious damage, leading to the hard disk can't boot.
Zero track damage belongs to one of the hard disk bad word, just because of its position is too important, so once destroyed, it will have serious consequences.
Usually the maintenance method is through the Pctools9.0 DE (disk editor) to repair (or similar to disk sector editing tools can also), the method is as compaq presario a903xx laptop keyboard follows:
With Windows9x startup disk boot, insert contains Pctools9.0 CDS. Operation of PCT90 directory DE. Exe, first enter the "Options" Tab menu, choose "Configuration" (Configuration) command, press "Spaces" key remove ReadOnly (read only) in front of the hook (according to the Tab key switch), later, save exit. Then Select and implement the main menu "Select" (choice) of the Drive (driver), in later in the "Drivetype" (Drive type) of paragraph, the choice of Physical (Physical), and press the blank space selected, and then click "Tab" key switch to "Drives" item, Select the "Harddisk" (hard disk), finally, Select "OK" and press enter.
Later, back to the main menu, open the "Select" menu, then will appear PartitionTable (partition table), selected and enter, then there are hard disk partition table information. If there are two hard disk partitions, l partition is disk C, this partition from hard disk 0 cylindrical start, then, will be 1 division of the BeginningCylinder from (cylindrical) of 0 to 1 is ok. Save then quit.
Note that compaq presario a904tu laptop keyboard in before modification will drive the important material backup out. Restart, according to the Delete button to enter back to the CMOS setup, choose "IDEAUTODETECT", we can see that CYLS number than the original reduced 1, after that, save Settings and exit. To partition, formatting, can save hard disk.
Note: because DE tool only to FAT16 partition hard effective, therefore, the FAT32 drive for the hard disk, it may through the partition master (PQ) disk tools, will FAR32 convert to FAT16, and then carry on the treatment.
In addition, there are some exploration out through the modified hard drive motor positioning system to change zero track position and through the circuit adjustment to change the distribution of the magnetic head logic, in order to achieve repositioning zero track purpose. Of course it needs more profound hardware level, the realization rise also more complex.
Partition table damage repair
Hard disk master boot record in the sector is also virus key attack place, through the destruction of the master boot sector DPT (partition table), can be easily damaged hard disk partition information.compaq presario a905tu laptop keyboard Partition table damage usually is not a physical damage, but partitioned data is destroyed. Therefore, usually, can use the software to repair.
Normally, hard disk partition after backup a partition table to floppy disk, CD or USB disk is very wise. This aspect, the domestic famous rising antivirus software provides a complete solution. In addition, for no backup partition table of the hard drive, also provides corresponding repair methods, but the success rate is relatively low.
In addition, Chinese disk tools DiskMan in this aspect is also great trouble-makers. Reconstruction partition table as one of its important function, very suitable for used to repair damaged partition table.
For the compaq presario a906tu laptop keyboard hard disk partition table was zoning adjustment software (or virus) serious damage, cause the hard disk and system paralysis, DiskMan can not be destroyed by the partition boot record information to establish partition table. In the menu choose toolbar "rebuilding the partition table", DiskMan namely began to search and rebuild partition. DiskMan will be the first to search 0 cylinder 0 head from 2 sector began to the implicit sector, looking for virus moved the partition table. The next search each head first sector. Search process can use the "automatic" or "interactive" two kind of way. An automatic way to keep found each partition, it is suitable for most cases. Interactive way to find every division are giving prompt, selected by the user is retained. When an automatic way to reconstruction of partition table is not correct, can use interactive way to search.
But, you need to be aware that compaq presario a907tu laptop keyboard reconstruction partition table function cannot do one hundred percent of the repair partition table, unless you've backup a partition table, and then through the reduction before backup partition table to repair damaged partition table. So visible, usually backup a partition table is so necessary!

Refuse to blank screen: HP DV3802 notebook fan transformation
By bobo anthony on Sunday, August 26 2012, 14:09 - laptop cpu fan
Bought old colleague the elder brothers HP DV3802 notebook hp pavilion dv4 series laptop cpu fan, he has been put in the home use, DV3802 is HP famous blank screen notebook. I got the hand, also
think acura heat ah. In order to solve because temperature is too high lead to HP DV3802 blank screen, so want to work hard the transformation.
HP 3000 series are a special fine linear heat pipe, heat dissipation is very poor.
HP DV3802 radiator the above the blue is the famous HP blue small wadded jacket, thermal conductive performance special bad, through the hp pavilion dv5 series laptop cpu fan measurement, blue
cotton-padded jacket and the contact area between the video card 1 mm spacing. So I went to buy a piece of copper sheet, in the market 8 yuan to be able to
buy a piece of the (MTOOU. INFO note: on taobao $2 a), and bought a 2000 sandpaper, fine sand paper can better grinding.
I will display card surface is a new grinding, as if a little oxidation, the contact is not very smooth.
This is a motherboard chip and occurrence of chip, although calorific value is not big, but HP also use the blue small wadded jacket. Sad reminder ah, why
can't you use good point?.
The above is calorific larger. Although we feel is never to, but used calculation opportunity very card.
In fact HP notebook and a fever big thing, that is hard disk hp pavilion dv7 laptop cpu fan, hands in the bottom left corner position, temperature can be high to 55 degrees, I put the next
to the PCI slots of the plastic block slice to go to, a little better, recently do a special fan blowing it it.
CPU, video card, hard disk temperature and pressure test
I use the software open pressure test, the CPU work can to 100% I opened a night, this chart is to begin testing 5 minutes to catch, test a night CPU can the
highest to 80 degrees, video card can to 75 degrees, hard disk 56 degree. Why CPU card than high, because the temperature of the video card out of time will
pass CPU hp pavilion dv5 laptop cpu fan part.

Make hard disk longevity method
By bobo anthony on Saturday, August 25 2012, 04:37 - laptop cpu fan
Make hard disk longevity method 1, keep the computer fujitsu lifebook n6470 laptop cpu fan work hard to clean environment with ultra fine filter paper breathing hole and the outside world are interlinked, it can be in common without purification device used in indoor environment, if in the dust serious environment, will be adsorption to PCBA surface, spindle motor internal and blocked respiratory filter, and therefore must be dust. There are environment humid, voltage instability could lead to a hard disk damage. Make hard disk longevity method 2, form the habit of leaving her cell phone right hard at work suddenly shut off the power and may lead to head and disc violent friction and damage to the hard disk, still can make head can't correct reset and cause hard disk scratches. When shutdown must pay attention to panel hard light is still shining, only when the hard disk light stop twinkle, hard disk end, speaking, reading and writing rear can shutdown. Make hard disk longevity method 3, correct mobile hard disk, pay attention to shock mobile hard disk when had better wait for more than ten seconds off hard disk completely stall of the reentry after. In the boot disk high-speed rotation, gently shake may disc and the read/write head mutual friction and produce magnetic stripe bad rail or damage to read/write head. So in the boot condition, don't move hard disk or chassis, had better wait for more than ten seconds off hard disk completely stall after the mobile host or restart power, can avoid power fujitsu lifebook p3010 laptop cpu fan supply for instantaneous surge to the hard disk drive cause harm. In the hard disk installation, remove the process should be more careful, hard disk mobile, when it comes to transport it is strictly prohibited to knock against, had better use foam or sponge packaging protection to it and try to reduce the vibration. Note: the hard disk manufacturers of so-called "resistance to bump ability" or "shock system" and so on, refers to the hard disk before starting state of shock, resistance to bump ability, rather than startup state. Make hard disk longevity methods 4, the user cannot open by hard cover in addition hard disk manufacturing and assembly process is in the clean environment, remember: general computer users unable to take apart hard cover, or the air into the hard disk in dust, high speed low flying head assembly rotary driving of dust or dirt may make head or disc is damaged, cause data loss, even if still can continue to use, hard disk life also can greatly shorten the, even can make the whole piece of hard disk scrap. Make hard disk longevity methods 5, protect against high temperature, moisture, preventing electromagnetic interference hard working condition and use life and temperature have very big concern, hard disk temperature in use in 20 ~ 25 ℃ advisable, temperature too high or too low can make crystal oscillator clock basic frequency change, still can cause hard drive circuit component failure, magnetic medium due to the thermal effect and cause records error; Temperature is too low, the moisture in the air will be condensation in integrated circuit element, cause a short circuit. Also can use software to monitor your hard disk temperature DTemp is one hard disk temperature monitoring fujitsu lifebook p3110 laptop cpu fan software, it can real-time users to report hard working temperature, and allow users to customize a temperature of the upper limit value, prevent hard disk for high temperature and appear work unstable condition. Can in the celestial pole download channel download to this size is only 93.5 KB software, after decompression software after you will find in the task bar at the bottom of the screen there was a driver in the form of small ICONS, above the icon with a changing temperature display, the temperature is hard drive current working temperature. Double click the icon will appear a set interface, among them, the "Check temperature every (1) minutes" a to detect hard disk temperature cycle, it is recommended that you choose the default Settings (a minute a). "HDD critical temperature (40) ℃" a hard drive for setting the temperature of the upper limit value. Here needs according to user use hard drive speed and decide, if it is 5400 transfer of hard disk, the proposal set to 40 ℃, 7200 turn, can be set to 50 ℃. With color to choose "Normal temperature color" and "Critical temperature color" two for hard disk in Normal temperature and beyond the upper limit value of the different status display, you can choose according to his be fond of, as long as can be marked. Optional "Warning about critical temperature" is to let the user to select when hard disk beyond the fujitsu lifebook p5010 laptop cpu fan upper limit value, is Warning? There is no doubt that we should select "yes". "Warning about SMART failure" a is to let the user to select when hard disk "SMART" technology found hard disk problems whether warned that this to the hard disk drive safety is very important, suggestion choice "is". Humidity is high, the electronic components surface may adsorption a layer of water film, oxidation, corrosion electronic circuit, so that the bad contact, or even short circuit, still can make magnetic medium magnetic change, resulting in the data error, speaking, reading and writing. Humidity is too low, easy to accumulate a large amount of by the machine derived from the rotation of electrostatic charge, the static electricity will burn out CMOS circuit, adsorption dust and damage to the head, scratches disk. The telecom room humidity to 45 ~ 65% advisable. In addition, try not to make hard disk near the strong magnetic field, such as speakers, horn, etc., in order to avoid hard disk data recorded by magnetization and damage. Make hard disk longevity methods 6, to regular finishing hard disk regularly finishing hard disk can improve the speed, if too much debris accumulation not only access efficiency drops, may also damage the track. But don't often tidy hard disk, that will also to hard disk life. Make hard disk longevity methods 7, pay attention to prevent viruses and Trojan horse program hard disk is a computer virus attack key goal, should pay attention to using the latest anti-virus software to protect against the virus. Want to periodically to the hard disk drive for antivirus, and pay attention to important data protection and regular backup. Suggest usually don't run the unexplained applications and open E-mail attachments, run before must first check viruses and trojans. Make hard disk longevity method 8, correct and hard disk method in computer maintenance should be hand fujitsu lifebook p5010d laptop cpu fan caught on both sides of the hard disk, and avoid direct contact with the circuit board, gentle with, don't knock against or and other hard objects collided; Can't use hand casually touch hard disk at the back of the circuit board, because the hand may have electrostatic, electrostatic can harm the hard disk electronic components, lead to can not run normally. And don't charged plug. Make hard disk longevity methods 9, let hard disk intelligent rest let hard disk intelligence into "closed" condition, to the hard disk drive work temperature and service life to give a lot of help, the first to get into the "my computer", with the mouse left click on "control panel", and then select "power management," will be the "closed hard disk" a time set to 15 minutes, after the application can exit. Make hard disk longevity methods 10, easily don't low case do not easily to hard disk low-level formatting operation, to avoid unnecessary blanks performance influence. Make hard disk longevity methods 11, avoid frequent high-level formatting operation it the same to disc impact performance, in not to partition, can use add parameters "Q" quick format command. Make hard disk longevity methods 12, hard disk fujitsu lifebook p5020 laptop cpu fan appear when bad word hard if there is a bad way, even if is a cluster may have a diffusion destructive, in guarantee period should be sought as soon as possible merchants and manufacturers replacement or repair, has the guarantee period as far as possible to reduce to format the hard disk, reduce bad clusters diffusion. Make hard disk longevity methods 13, make good use of disk tools to make good use of all kinds of disk tools, such as Norton Utilities, Norton CleanSweep, timing to clean their hard disk, it can improve system efficiency. Make hard DISK longevity methods 14. Establish RESCUE DISK use Norton Utilities tool software will hard DISK partition table, boot record and CMOS information save to floppy DISK, just in case. Make hard disk longevity methods 15, try not to use hard disk compression technology when the compressed volume file gradually increases, the hard disk, speaking,fujitsu lifebook p5020d laptop cpu fan reading and writing data greatly slows down the. If a disk capacity enough, there is no need to use in hard disk compression technology.

Win7 operating systems play the mouse wheel five skills
By bobo anthony on Thursday, August 23 2012, 04:26
In Win7 system, in addition to the used fujitsu lifebook p7120 laptop keyboard to turn the page browsing, the mouse wheel still have a lot of interesting little function. Now look at Win7 system under the mouse wheel five small skills.
1. In the background the new tag open web link
Does not support "super drag" let the IE browser users have been very ravel, in fact as long as in a web page with the mouse wheel click on the links, you can in the background in the open a new tag links. This function can be used in all browsers.
2. Close the page label
The fujitsu lifebook p7120d laptop keyboard mouse wheel in the background new labels, can also be a closing tag. Similarly, in web label press the mouse wheel, which can be closed.
3. Fast switching folder view
4. Enlarge or reduce page font
Some web page font is lesser, look bad old people read a bit difficult, at this time as long as hold on the keyboard CTRL key, at the same time will the mouse wheel scroll up, can will web proportional amplifier, web page the font goes the amplification.
Press Ctrl + 0, can quickly return to original size. (switch input method: input method switching not how to do?
5. Automatic GunBing
The mouse wheel turn the page is very convenient,fujitsu lifebook s2110 laptop keyboard if can let the page yourself rolling is better, so look on the net novel, or read a long word documents, still can make hand to eat snacks! The mouse arrow moved to web pages or documents, downward click the mouse wheel, with "da" a sound, the original the mouse arrow will become a top and bottom is or so four arrows, or only has two arrows of the dot.
At this time, the upward or downward moving the mouse, the page will be a small black arrow upward or downward automatic GunBing, small arrow distance just press the origin of more far, GunBing speed is faster.
No longer need to GunBing, just click the left mouse button can be restored to the original state.
Browse folder, you can through the switch view to change the file list representation. In the past we need in the right mouse button menu, or through the folder window top right corner of the switch button to modify the view, as it is in Win7, as long as the CTRL key fujitsu lifebook s6210 laptop keyboard, and then rolling the mouse wheel can be convenient to switch the folder view.

Notebook batteries electric general how long can
By bobo anthony on Wednesday, August 22 2012, 04:06
Question: my laptop is full of electric see a movie brightness dozen to samsung x15 laptop keyboard a minimum, how only 1 hour, isn't the battery has a problem, take to repair, repaired or, what is the problem? The notebook battery in normal use or idle for a period of time later endurance will accompany with charging and discharging frequency and reduced to oh, don't know your laptop battery for long, have a notebook battery loss
Question: my laptop samsung x20 laptop keyboard is full of electric see a movie brightness dozen to a minimum, how only 1 hour, isn't the battery has a problem, take to repair, repaired or, what is the problem?
The notebook battery in normal use or idle for a period of time later endurance will accompany with charging and discharging frequency and reduced to oh, don't know your laptop battery for long, have a notebook battery loss said, meaning that no matter use or not cell itself will have discharge phenomenon, is just use will accelerate this process, the capacity of the battery is smaller and smaller. If this is the case, customer service is no way.
Usually buy a new notebook random zone of the battery for 4/6 core, need some large capacity of battery need to explain in advance add money to buy samsung x25 laptop keyboard! Use a period of time, can depth charge and discharge a time to adjust, the only for numerical control, the battery to actual endurance time shall prevail.
4 core battery standby time is 2 hours using the time for about 1 hour
Six core battery standby time for 3 hours use time is about 2 hours
8 core battery standby time is 3.5 to 4 hours use time is about 3 hours
9 core battery standby time was 4.5 hours can probably use 3.5 hours
12 core battery standby time for five to six hours probably use time is 4 to 4.5 hours
How to see the notebook battery loss rate:
The normal use notebook battery produces the loss is normal phenomenon, basically to the notebook the change of time, the battery will just use about, about 2 ~ 3 years of time (according to the use frequency of battery to judge), blunt once electric also can only use 1 hours of state, how to reasonably use notebook power option Settings, reduce the number of charge and discharge, perhaps can prolong the life of the notebook samsung x30 laptop keyboard.

Computer repeated start and crash processing
By bobo anthony on Tuesday, August 21 2012, 03:50
A compatibles, its configuration is: P4 1.8 GHz CPU ibm lenovo thinkpad t61 6378 laptop cpu cooling fan, gainward GeForce3 Ti 200 graphics, off-brand 845 d motherboard, Hynix 256 MB DDR memory, Seagate 80 gb hard drive, samsung 17 inches flat sc-reens, etc, the operating system is using Chinese Win98 SE. Just started to use few months computer work or very normal, but by the end of November last year one day, computer boot suddenly puzzling crashed, restart after all still calculate normal, just run a few more consumption system resources of the program, more likely to crash turned out to be much bigger. But the author in addition to typing, surf the Internet, but for other application requirement is not much, so also do use. But from the start in January this year, the computer appeared a kind of "strange disease," every time when powered up all need in the over power button, then according to the Reset button to restart to work properly.
Breakdown maintenance
According to the general system halted fault inspection train of thought, in the ibm lenovo thinkpad t61 6379 laptop cpu cooling fan spirit of "first after soft hard" principle, the author first the heavy Win98 SE, but failed to solve the problem. Then trial assembly Win2000 and WinXP, although the installation process are all very well, but failure phenomenon but remain as before, and on the basis of the author decision this fault should be independent system software. Then replaced a Great Wall 300 w new power, but still did not eliminate the fault. Upon confirmation of hard disk no bad way, the author and in turn replaced memory and graphics, when using a piece of small sized photograph of the GeForce2 MX440 graphics to replace the original graphics, fault finally disappeared.
The author thought it comes out of the question, the GeForce3 Ti 200 video card inserted in the other a normal computer ibm lenovo thinkpad t61 6457 laptop cpu cooling fan test, but do not have any problem! At this time the author began to suspect that may be motherboard have a problem. But after careful analysis and think there seems to be no reason, just assembled it worked quite normal! Don't is its AGP slot have bad contact problems? But after replacement display card is running well! Looking at two pieces of graphics, the author abrupt fantasy, is due to GeForce3 Ti 200 video card consumption power is larger, the motherboard AGP slot power supply shortage, or for AGP slot power supply circuit element potential issues, resulting in graphics in the working voltage of the lowest near the critical point?
To test the idea, the author will motherboard down from ibm lenovo thinkpad t61 6460 laptop cpu cooling fan the case out, in the light of the strong under the environment of careful observation AGP slot surrounding components, found that there are two with small aluminum radiator and on the mainboard dimension for SD12, SD13 power device, it is estimated that they should be for AGP display card power components, but the appearance observation has not found to have obvious abnormal phenomena. So the author and gainward GeForce3 Ti 200 graphics put back to the main board, and restore all the hardware connection. Then in the computer successful start, the digital thermometer probe were inserted in the motherboard AGP slot power supply for the two dc switch power tube aluminum heat sink in.
And then run the easy to crash the game program, at the beginning of their temperature display digital as 25 ℃ or so, only for about 10 minutes time, the temperature at the same time reached 52 ℃, SD13 temperature numerical suddenly slumps, meanwhile computer crashed. The author overjoyed, immediately cut off the power supply of main computer, and then remove the SD13 of fin and solder iron welding the element, using a multimeter to electric stop check each electrode on-off resistance,ibm lenovo thinkpad t61 6466 laptop cpu cooling fan but did not see any unusual. Look at the cell surface, dimension model for FP45N30T, because the author hand not model the same power tube, so they use a package volume roughly the same silicon NPN power transistor do replace test, the results of computer start returned to normal, and then run some larger program no longer appear crash phenomenon. Even if the computer continuous operation for a long time, two dc switch power tube fin highest temperature also only up to 30 ℃ or so.
summary
Afterwards the author analysis, cause the system halted the main cause of fault, is the main board for AGP slot power supply two power tube in a because exist some defects, which supply in large current occurs when the interelectrode cut-off condition. We can see the author draw out of the circuit diagram, from the graph, we can see that, this circuit is a kind of typical "energy saving control" type double tube parallel power output form ibm lenovo thinkpad t61 6480 laptop cpu cooling fan. When AGP CARDS power consumption is low, the control chip will SD13 tube is responsible for all this power output closed, so as to achieve the purpose of saving energy. And when the graphics card electric power consumption, the control chip will automatically open we should power output.
SD13 tube for some reason the performance parameters changed, in the computer just boot AGP slot power supply should be the SD12, SD13 two pipe share responsibility, but in fact but now SD12 to bear, causing the output current in graphics minimum working current point of critical point. As we all know, high power dissipation of the start of the current video card need is very big, so the computer will appear one-time start failure problem. Choose after restart, because in the last card under the impact of starting current,ibm lenovo thinkpad t61 6481 laptop cpu cooling fan power consumption reduced, so start can be successful. But the power supply capacity also is only scrape by, so when graphics high-speed work will appear the phenomenon of crash. And GeForce2 MX440 graphics power consumption relative to lower, at this time due to the energy saving control circuit has been closed the SD13 power supply circuit, natural computer can work properly.

Notebook sleep and dormancy have what differentiation?
By bobo anthony on Friday, August 17 2012, 03:44
Recently there are net friend ask: notebook sony vaio vgn-n160g laptop keyboard sleep and dormancy have what differentiation? In the beginning of my notebook menu shutdown options see in addition to shutdown and restart, cancel there are two, sleep patterns and sleep mode, the two mode have what distinction, how to use, the following edit finishing the relevant data and share next.
"Sleep" is a kind of energy saving state, when you hope to work again, can make the computer quick recovery full power work (usually in a couple of seconds). Let the computer sony vaio vgn-n170g/t laptop keyboard into the sleep state like suspended DVD broadcast machine: calculation opportunity immediately stop work, and continue to work well preparation.
"Resting" is a mainly for the portable computer design power energy saving state. Sleep usually will work and setting up the stored in memory and a small amount of electricity consumption, and dormancy will open documents and program save to disk, then shut down the computer sony vaio vgn-n170g/w laptop keyboard. In Windows using all the energy saving state, dormancy use power at least. For portable computer, if you know there will be a long time not to use it, and during that time could not give battery charging, then you should use suspend mode.
"Hybrid sleep" primarily for desktop computer sony vaio vgn-n170g/w laptop keyboard design. Mixed sleep is sleeping and resting combination - it will all open documents and program save to memory and disk, and then let the computer into the low energy state, so that can quickly return to work. So, in the event of power failure, Windows from the hard disk to recover your work. If opened the mixed sleep, let computers are going to sleep at the same time, the computer automatic into the mixed sleep state. In the desktop computer, mixed sleep usually the default is open state.

How to disassemble the notebook power adapter
By bobo anthony on Thursday, August 16 2012, 04:11
The notebook computer hp compaq udqfrzr01c1n laptop cpu fan power adapter are all sealed small volume design, and the consumption of power can generally be up to 35 w to 90 w, so the internal temperature is higher, especially in hot summer, touch the power adapter will have a hot feeling. Because of this, power adapter failure rate relative notebook computer other parts is relatively high. Power adapter damage, buy a new spend hundreds of yuan, to the secondary market tao also needs the multivariate. In fact, many power adapter damage is not serious, slightly understand some circuit knowledge user can try to repair
Ready to electric knife, a hammer, screwdriver, electric iron, pen knife, etc.
The notebook computer power adapter and cover for injection molding packaging or with strong adhesive joint, need not any screw, so general can only resort to violence to crack. However,hp compaq cq42-100 laptop cpu fan as long as the method is proper, after disassembling the power adapter can bounce back, don't watch carefully almost can not see a trace of apart.
The power adapter lateral side placed on white paper, with electric knife edge along the power adapter and cover the gaps between the cut, and then use a hammer percussion electric knife knife back (as shown in figure 1), make electric knife from adapter between up and down cover cut in. In the adapter and cover the gaps between the different position, with electric knife point along the hp compaq cq42-200 laptop cpu fan gap paddling, when fluctuation cover some place first crack, the blade deeply, then slowly separate adapter and cover.
Then open the enclosure of the power adapter, you can see adapter circuit external bread has a copper shielding layer, use pen knife cut open shielding layer on the tape paper, reoccupy solder iron welding open shielding layer and internal circuit board connecting two solder joints (see chart), namely under wired shielding layer.
Shielding hp compaq cq56-112 laptop cpu fan layer and circuit board still between every one layer is thick hard plastic film (as shown in figure 4), and then on the edge with art design knife cut open, can see circuit board "looks like"
1. Pressure sensitive resistance, its function is when external voltage is high, the pressure sensitive resistance value quickly become small, and pressure sensitive resistance tandem fuse was blown fuse, in order to protect other circuit will not be burnt out.
2. Fuse, the specification is 2.5 A / 250 v, when the current in the circuit is too high, the fuse will fuse to protect other element.
3. Inductance coil (also called reactor), the main function is to reduce electromagnetic interference.
4. Rectifier bridge, specifications for D3SB, the function is the 220 v alternating current (ac) to direct current.
5. Filter capacitance, specifications for 180 u F / 400 v, the function is filter in the dc ac ripple, make the circuit work more reliable.
6. Op-amp IC (integrated circuit), the protection of circuit, voltage regulation is an important part of.
7. Temperature probe, for detection of power adapter internal temperature, hp compaq cq56-115 laptop cpu fan when the temperature is higher than a set value (different brand power adapter, the set temperature valve value slightly different), to protect the circuit will cut off adapter voltage output, in order to protect adapter from being damaged.
8. High power switch tube, is the core element of switch power supply, switching power supply can "opening and closing" work, responsible for the switch tube.
9. Switch transformer, switch power supply of one of the core elements.
Secondary rectifier tube, the function is the low voltage ac into low voltage dc. In the IBM power adapter, rectifier often is made up of two large power parallel work, to get bigger current output.
11. The secondary filter capacitance, specifications for hp compaq g42-300 laptop cpu fan 820 u F / 25 v, a total of two, the filtering low voltage dc in the role of the ripple.
In addition to the above element outside, circuit boards and adjustable potentiometer and other resistance capacity element.
