Step 1: Remove Hinges (free the display)
I used my first generation G4 powerbook for this project, which already had the hinges broken, so this was a bit easier for me than it will be for you. Although, you can easily break the hinges off by folding the monitor back. I also ripped off that little back flap before I began, but be WARNED a little piece of metal might fall into your laptop when you do this, ruining it. I would finally suggest doing all the work on a soft surface, I used a towel on my bed.
To remove the hinges on this laptop take a torx-8 screw bit and remove the two screws in each hinge. (You can get these bits at radio shack if you dont have them.)
Pull off the hinge caps, though you may need a small flat head screw drive. NOTE: always be careful of the cables that carry the data (little and green). They're actually very small coax cables and can easily be ruined.
Now remove the inner metal hinges with the same screw bits. These should just come off after you unscrew them.
