I have a Titanium Powerbook G4 400Mhz. A while back, I closed the cover without properly shutting it down. It stayed in this state for two days as it was the weekend and I left the unit at work. Since this happened, I can only start it up by pressing the power button, then pressing the restart button on the back, then finally, pressing the power button again. I've run disk utilities to repair permissions and fix the disk but it indicates there isn't a problem. Disk Warrior also turns up nothing. Everything else seems to work fine (except I have to reset the clock and date each time I use the restart button - which I think would be normal?) Someone please help.
