Steps
1. Remove the eight screws (M2x3) that secure the base cover to the palm-rest and keyboard assembly.
CAUTION:
Do not pull on or pry the base cover at the side where the hinges are located; doing so may
damage the base cover.
CAUTION: Do not pry open from the top of the computer as this will damage the display FPC.
CAUTION: The base cover is preassembled with the audio-daughter board. The pins at the bottom of the
base cover are fragile. They ground the antennas and audio-daughter board. Place the base cover on a clean
surface to avoid damage to the pins.
2. Starting from the bottom-left corner, use a plastic scribe to pry the base cover in the direction of the arrows to release the
base cover from the palm-rest and keyboard assembly.
3. Grasp the left side and the right side of the base cover and remove the base cover from the palm-rest and keyboard
assembly.
