Battery Not Charging

Did you reset the PMU (power management unit) and re-calibrate the new battery ?

I am having a similar, albeit not exact program. I shut down my comptuer last night, tonight when i got home, it was real hot and apparently ahd still been on. At first it wouldn't start up and I had to press power button a couple times. I plugged in teh adapter but it has been stuck at 97% charged for over an hour now. I literally just got this thing two days ago - no reason why the battery should not go to 100% - any ideas???

Reset the PMU:

Shut down computer

unplug power

Remove Battery

Press the ON button for 10 seconds with the battery out, and the cord disconnected.

Replace battery

Replace cord

Turn on computer - PMU reset.

Charge the battery (if it will) to full, then run down to 0 again, and full again, and your battery should be optimized


If it doesn't fix after the PMU reset, bring it in!!!!

Yes, I am having the exact same problem. I got the replacement battery about a week ago, everything worked fine until today, now the battery is down to 0% and is not charging. One little green light flashes when I press a button on the battery. The power adaptor has its yellow light on ( I have a powerbook G4). I reset the power management unit, removed/put back the battery, ran disk repair, reset PRAM. I'm continuing to search the forums, please post if you find anything out.

Sorry, missed this ...
