I was given this as a gift (for helping them move from OS 9 to OS X (yes they have been using OS 9)). and Its really kool but it wont power on it did once but nothing on the screen popped up (I heard a bong and a drive start up and everything) but then had to leave it for a bit. The person who gave it said when they powered it up on friday it worked fine. So I came back about an hour later and now nothing. So I first take out the battery its still got 3 little light bars when I press the button thingy (getting the AC adapter tomorrow when I teach them there final lesson..... they grow up so fast ). Any ideas?
