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.

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

Take back the cover

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.

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 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.
