Hi,
I have a PowerBook G4. When I am connecting the AC, the LED on the cable attached to red, so that the battery is recharged, but even after hours of charging, the LED battery status will remain in the lower level. Macbook starts and runs, the battery indicator shows 0% and not for calculating the remaining battery time. Heard a very slight "twirping" type of noise at times since the problem occurred, it seems out of the battery ...
The battery is down and needs replacement? Does anyone have a clue?
