This part requires a phillips head screwdriver to remove the screws as well as a plastic spudger.
Turn off the computer, unplug all cables, and let it cool down. Lay the computer flat on its screen.
Remove the monitor stand screw in the bottom of the stand, and remove the stand completely.
Remove the two screws on the bottom of the computer, one on each side.
Locate the slot on the right side of the computer next to the screw hole. Use a plastic opening tool or spudger to pry off the rear cover. (Don’t be afraid to use a little force.)
Once it has been separated, lift to remove.
