Remove the seven M2.5x8 screws securing the palmrest panel. These screws all have arrows pointing to them.

Remove the four oddball M2.5x4 broad-head screws under where the battery was.

There is also another screw, under where the disc drive faceplate was, which has a screw cover on top of it. This screw has an arrow pointing to it, too. This screw is of an M2.5x4 size.

Remove the four M3x12 screws. These, too, are different from the others, so keep them separate.

Flip the laptop over, open it, and pull up on the palmrest panel (or use a plastic spudger).
