BTW, one of the most useful tools I've found for working on arbitrary modern electronics (after a basic set of ordinary screwdrivers and jewelers' drivers, a needlenose pliers, and some kind of spudger) is a $10-$20 set of as many different security screw bits as you can get. IME, it pays for itself the first time you need one of the bits, and I wish I'd bought a bigger set the first time.
