Often have a computer Laptop Battery enthusiasts to the author feedback, the main computer noise, but don't know how to solve. For most used longer computer may produce host noise. If you find the main computer noise is very big, might as well the author recommended for its way to rule out. Notebook fever cause exploration
 
First we first say the main computer HP COMPAQ Business Notebook NX9020-PG627ES Battery noise from what place. We know that the main computer main components include: processor, memory, and video CARDS (video card set to ignore, motherboard, hard drive, power supply, computer hardware, easy to produce noise accessories mainly has: the processor (mainly a cooling fan), video card (mainly refers to the independent video card), hard disk last may also is the memory. Memory this actually out noise is less, even if there is also associated with the computer of failure, so strict said memory can also ruled out.
The main computer noise what happened-the noise source
The main computer HP COMPAQ Business Notebook NX9020-PL539UA Battery noise what happened-the noise source
 
We know that the main noise source of computer host, next, we will need to find the source of the noise host, if your computer host appears more noise, so first open computer case, then open the computer, observation and listen carefully to the noise source area.
 
A: if only buzzing sound, the most is the sound of a fan, because use the fan too long, internal drying, natural meeting has some small buzzing noise, these belong to attribute normal phenomenon. If need to solve this fault can CPU fan will come down and the comprehensive clean up the HP COMPAQ Business Notebook NX9020-PL637US Battery dust, and on some fan lubricating oil of what effect will be immediate.
 
2: obvious kaka noise
 
Significant kaka noise, and many times is the power cord or CPU fan the power cord and disk fan line against the CPU fan or video card to the cooling fan.
 
Solution: off the computer, a closer look at the line and didn't meet fan site, this just when listening to the general direction can be judged, rearrange the line can be solved generally.
 
3: noise source position hard disk
 
Hard drive HP COMPAQ Business Notebook NX9020-PN688LA Battery internal disk damage is easy to produce noise, mainly is the head and avoid friction makes noise, appear this kind of circumstance noise general is obvious, with the hand to touch hard disk will feel as strong. Has this kind of situation that hard disk has been in a is damaged. Now suggest that we do data backup, recommend replacing hard disk, in order to solve the noise and data security.
 
4: noise source power supply
 
Computer power supply is also easier to produce noise accessories, general noise source power HP COMPAQ Business Notebook NX9030-PG523UA Battery source and a cooling fan computer's internal circuit. The most common noise source power supply cooling fans, we look at and listen to is easy to judge to the site, solution: if power supply in guarantee period, the proposal to take to the warranty, in addition the warranty has been old power, can try to clear dirt. Additional power supply circuit inside a small issues will also produce all sorts of strange noise, such as internal transformer faults easy to produce the harsh can't express noise, suggested that replace the power supply or repair.
 
The main computer HP COMPAQ Business Notebook NX9030-PG571EA Battery noise of the causes and solutions is these, some independent video card can also produce noise, everyone according to above methods to judge solve. There is no detailed introduction, for the main computer noise what happened, believe you already know a probably.
