PowerBook g4 12" shut down unexpectedly when I opened the lid fully, now won't start This is a 2004 ibook 12" G4. It has a new battery, new charger, everything else seems to work fine, but when I opened the lid all the way yesterday (perhaps a bit roughly, torquing it somewhat I suppose) it just died and will not start at all when I press the power button. Charger glows green. NOTHING happens when power is pressed. Is this a hinge issue? Replacement lids are like $10 on ebay; is it a major hassle to swap one of those? Is there any way to determine if that is the problem BEFORE buying a new screen? Help.
