1. Method 1: First, turn the machine upside down, take out the battery and unscrew all the screws on the back cover; Remove the small leather pads at the four corners of the computer, unscrew all the screws inside and take off the back cover.

2. The second method is to turn the notebook upside down and push the fixing button of the battery outward to the end; Push the movable buckle outward with one hand and take out the battery with the other hand; Erect the notebook and unscrew the screws that fix the back cover; Lay the notebook flat, press it gently, and then remove the back cover.

The specific operation is as follows: after removing the battery, stand the notebook upright and unscrew the screw that fixes the back cover. It should be noted here that if there is a trademark on the battery slot, pay attention to uncover the trademark, and there will often be screws hidden under the trademark. If all the screws are not removed, the back cover will not open.

After the screws are removed, lay the notebook flat, gently press it and push it down to remove the back cover. Never insert a sharp tool such as a knife into the seam of the back cover and lift it, because there is a buckle above the back cover, which will easily lead to the buckle breaking.
