Question about Apple PowerBook G4 Mac Notebook
Common fix for this problem is a simple Power Management Unit (PMU) reset. This will basically re-sync the battery "brain" to the computer so they when when to charge and when to stop. To do this, simply turn your computer off, remove battery and power cord and hold the power button down for 7-15 seconds. Then you MUST wait 15 seconds after pressing the button before applying power or inserting battery. 75% chance this will fix your problem. If Not, Replace Adapter/Charger. They have a microchip in them that can go bad that senses when to send more current to charge battery. Apple motherboards are generally better built so I'm not suspecting that at this moment. Let me know what you find out.
