So I'm not sure what the problem here is, but the ibook worked fine, then pretty much went blank and never woke up. Not sure what to do here, but before the whole thing stopped working, the computer wouldn't go to sleep when you closed the screen, and I'm wondering if something overheated? The computer still sees the charger (turns green because the battery is charged) but other than that the computer is unresponsive. Any ideas on what to do?
