It can be said that any notebook has been used for more than three years, no matter how clean your environment is, you must remove the back cover to clean the dust. The usual advice is to clean it once a year. Otherwise, the computer will become stuck more or less, the keyboard will feel hot after running for a period of time in summer, and even some large games will crash. ...

Speaking of ash cleaning, everyone knows its benefits, and most people choose to ignore it, mostly because it is too troublesome to go to a professional repair shop, and they can't do it themselves, or dare not. On the other hand, what dares to clean the notebook? Why can't you sweep the world without sweeping? I dare not even clean the dust. What about high-level events such as reading, doing business, saving money and pursuing Bai Fumei?

So, how did the laptop remove the back cover to clean up the dust?

Take the notebook as an example to teach you how to disassemble and clean it. Although everyone's notebook type may be different, the methods of disassembly and cleaning are basically the same. You can explore it yourself according to the tutorial.

Tool materials:

First, take out the battery.

0 1

Turn the notebook upside down, and first push out the battery retaining button to the end. Notebook batteries always have two buckles: a fixed buckle (which will not bounce back if pressed) and a movable buckle (which will bounce back if not pressed), one on each side.

02

Then, the other hand pushes the movable buckle outward, while the other hand takes out the battery downward.

Second, take the back cover.

0 1

After taking out the battery, stand the notebook upright and unscrew the screws that secure the back cover.

Here, I would like to remind everyone that if the battery tank has a trademark, pay attention to unveiling the trademark. Often screws are hidden under trademarks. You can't open the back cover without removing all the screws.

02

After the screws are removed, lay the notebook flat, gently press it and push it down to remove the back cover.

I would like to remind everyone that sharp tools such as knives must not be inserted into the seams of the back cover and lifted upward. This is because there is a buckle above the back cover, which is easy to break when lifted.

Third, clean the CPU fan.

0 1

First of all, mention the principle of cleaning CPU fan: remove screws as little as possible, and we don't need to take the fan out completely when cleaning.

For some models, to completely remove the fan of the machine, it is necessary to completely disassemble the back cover or even the front keyboard panel, which is thankless and prone to problems.

Here, just unscrew the screws that fix the fan and the fan baffle. At this time, although the fan can't be completely taken out, we can already use gadgets to sweep the dust.

02

After removing the above screws, open the baffle, carefully sweep the dust with a small broom, turn the notebook back after sweeping, and pat it gently to shake off all the dust.

Fourth, test the cleaning effect.

0 1

In order to ensure successful cleaning, we'd better test the notebook before installing the back cover to see if it has returned to normal. You can download a master Lu to complete the work.

The effect here is very obvious. Before the temperature and pressure test, the CPU temperature whistled for more than 80 degrees, and later it was turned off because the CPU was overheated; After cleaning, the whole test is always below 60 degrees.

02

In addition, it should be pointed out here that if you can't clean it with a broom, you can also use high-purity alcohol (which is sold in general pharmacies and is very cheap, so don't wipe it with water) and cotton balls. After cleaning, put the screws and the back cover back in place according to the reverse procedure of removal. Everything will be settled.
