How to remove the back cover of the notebook?

1. Turn the notebook upside down, and first push out the fixing button of the battery 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.

2. Then, push the movable buckle outward with the other hand, and take out the battery downward with the other hand.

3. After taking out the battery, erect the notebook and unscrew the screw that fixes the back cover. If there is a trademark in the battery tank, pay attention to uncover the trademark. Often there are hidden screws under the trademark. You can't open the back cover without removing all the screws.

4. After the screws are removed, put the notebook flat, press it gently, and remove the back cover. I would like to remind you not to insert sharp tools such as sharp knives into the seams of the back cover and lift them up. This is because there is a buckle above the back cover, which is easy to break when lifted.

5. 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.

6. 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.
