Remove the 10 PH0 Phillips screws that secure the palm rest to the computer base. 8 of which are 6mm long.

There are two screws which are longer (9mm) these are the orange highlighed screws in the picture

Using a spudger, pry along the edge of the palm rest to begin removing it.

The palm rest is held in with plastic clips all of the way around, so you will have to carefully pry all the way around it.
