Okay, as many who frequent this forum know, I have an iBook 500Mhz, a truly great computer, that has had a few problems. So far I've had monitor, Airport, trackpad, and software problems. Now a new one arises: the battery. It's 15 months old, and it's just not holding a charge anymore. With minimum backlighting and all the energy saver options on (slow proc speed, the HD spin down options on), and the AirPort card off, it loses 1% of charge in about 40-70 seconds... or so it seems. I say that because, one it hits 0%, instead of going to sleep, it stays at 0% for a half hour or more. I think the power manager may be corrupt but I don't remember in the least how to reset it. If anyone can help, thanks.
