Hey guys, I'm having this odd problem right now with my PowerBook. Just a while ago, I heard some odd buzzing noises that came from my laptop, so I decided to turn it off. It was plugged in, mind you. When I turn it back on and login, it shows that my date and time were reset (like you reset your PMU). I look at the battery icon, and it doesn't show that the computer is plugged in at all, even though it is completely plugged in with the adapter. The adapter shows amber on the charging ring. I have tried both the 2 pronged and 3 pronged (the one with the grounding thing) attachments for the adapter. Yes I have tried resetting the PMU and PRAM. Help is appreciated.
