[QUOTE="Melhof, post: 1169091, member: 186660"] [b]Powerbook full charge capacty 62Ah!![/b] Quite the same problem here. :'( Also my girlfriends Powerbook has the same battery problem. The full charge capacty is about 62822 mAh (62 Ah = the battery size of a car starter battery) I guess there has been a bad contact in the past and the laptop has been charging and charging till, meter kept on running till this crazy amount. Every compleet cycle it makes it goes down a little bit. (about 300 mAh/cycle) But it will mean that the value will be right in about 150 cycles... But my house works on a few solar pannels, so this is no joke... :Shouting: I have Googled around and done the PMU reset and also tried: command-option-p-r (reset PRAM) and command-option-o-f; reset-nvram; set-default; reset-all Also cleaned the battery contacts. The Ah memory chip is probably in the battery its self. And it does not get reset by the remedies above. Since this battery is not very good anymore i think about opening it. Disconnect the battery from the chip for some time and by that reset the chip. Any other solutions? I am open...:Oops: Greetz, Melchior [/QUOTE]
