Step 5: Keyboard removal and modification
Remove any screws that hold the keyboard to the top half. On many newer laptops, the keyboard comes off before anything else, in this case it comes out last.
Next, we are going to cut away the entire center of the top half using a dremel tool and a cutting disk or something like it. Use a file or some sandpaper to smooth everything out. Be careful, the plastic actually melts and you can get a pretty nasty burn.
