ok so my powerbook ran out of battery the other day so i plugged it in and tried to turn it on. i spent the next hour or so trying to do so, holding the power button, using different key combinations and such. but it wont turn on. its about 2 months old so it can't be a battery problem, but i noticed that the charger light will only turn orange, not green. there has to be sometyhing i'm missing because i really don't want to sent it anywhere for repairs (i'm working on a video and am anxious to start editing). any help?
