Pry both of the top rubber pads off with a metal spudger. They are attached to the base enclosure with adhesive.

When you will be installing these two rubber pads again, pay attention to their difference. Search for the letter "R" impressed on the base of one of them and stick that one in the bay which displays the "R".

Using a PH#00 screwdriver remove then the eight Phillips PM2.5x5 screws that secure the base enclosure to the laptop. Group these screws together.
