Our first step in cracking open the Cr-48's lid is removing the plastic piece that covers the hinge screws. It's held in place with plastic tabs. You should be able to pop it loose from the lid using a case opening tool, thin metal blade, or your finger nail (if they're strong enough).
With the hinge cover removed, you can also remove the Phillips screws that hold the hinges to the lid.
