I have no idea why my power book G4 12" which i bought in prestine, if not in mint condish just last december and which i hardly use (so as to keep it's state) just won't start up the way it normally should.. the way any mac laptop or desktop should. after charging it just the other day, i turn it on and i see no apple, no swirling start up wheel, no question mark, no nothing except for the apple grey color. thought it was just taking more time, for whatever reason but...even after an hour, it just didn't do a thing but stared at me cold grey. what is going on?! please help! :redface:
