I'm having a really weird problem with my powerbook (titanium 1ghz). Last night when I was using it it was working like it normally does. I usually get about an hour and a half out of a charge and about half the time I keep it plugged into the adapter. When I opened it this morning, it wasn't asleep like normal, but actually powered down. I turned it on. Thats when I noticed that the battery was at 0% and wasn't going up. I left the computer on and went to my first class and when I came back a couple hours later it was still at 0%. Thinking that maybe the meter was broken I unplugged the power from the computer and it instantly went into sleep mode and a couple seconds later it powered down. The light on the power adapter is green and not amber and the lights on the battery indicate that it's out of juice. I've tried reseting the PMU twice and nothing happened except resetting my clock. Is my battery broke? It seems weird that it would be working fine one day and be broken the next. Any suggestions?
