I'm in the middle of trying to replace the hard drive in my 15" G4 Aluminum PowerBook (my old drive died)- and am stuck on trying to free the latches behind the DVD slot. Has anybody else tried this? At first I was going by the IFixit Guide, but wasn't having any luck freeing the latch. Then I saw this other guide to opening the PowerBook and it says there are 3 latches instead of one... and tells you to insert a screwdriver in the DVD slot to pry the latches open. That's not working for me either. Does anybody have any tips on this? This is getting very frustrating.
