I've looked through a few pages of old posts, but I can't seem to find any specific solution to this problem, so here it goes. For about three months now, my Titanium PowerBook has been telling me the wrong battery life. When I unplug it, it'll stay at 99%, and then randomly fall to 3% or 7%, and tell me I'm low on battery life. This can happen at any time, from ten minutes from me unplugging it to an hour. I never know when the battery is going to die, it'll just stay at 3% until it turns itself off. I've tried draining the battery completely and recharging it fully, and all sorts of other tricks, but nothing seems to work. I think I'm getting about a two hour charge out of the battery at this point, by the way. Is it time for a new battery in this computer? Or is there some software issue I am not familiar with that could solve this problem? If not, where could I find a good, reliable, and *cheap* Pb battery? Thanks for your help!
