Steps to remove the bottom plate from the device.
There are 13 screws in the bottom plate that need to be removed. 1 in the middle left (when looking at the backplate) has a warranty sticker covering the screw locations.
Insert a spudger in between the bottom plate and the palmrest, and rotate the spudger to start releasing the clips along the bottom plate. Do this around the entire perimeter of the bottom plate.
Once the clips are released you should be able to lift the bottom plate away from the palmrest and put it off to the side.
* To reassemble follow the above steps in reverse.
