View Full Version : Strange Powerbook Battery Problem

Jan 2, 2007, 11:06 PM
I have a titanium powerbook which used to last about and hour and a half to two hours, but suddenly would only last for a couple minutes. Basically when i charge it it gets to 100% then gradually decreases to about 95% then suddenly crashes to 0%.

I just thought this was a battery that couldn't hold a charge, but when it crashes to 0% it can stay asleep for days, implying that the battery still actually does have a charge. Perhaps the computer is reading the charge wrong and just puts it to sleep when it reaches zero even though its not really completely dead. I don' know, could anyone help?

Yeah, calibrate your battery (http://docs.info.apple.com/article.html?artnum=86284), reseat it and reset its PMU (http://docs.info.apple.com/article.html?artnum=14449). However, I reckon this is sounding like a failing battery. Those are pretty standard signs that it's dying. :o
