No More Low Battery Warning

[Pili]

Computer is powerbook G4, high res model.

My computer/battery are about 14 months old and coconut battery says i have 97% capacity and 117 loadcycles on the battery.

When im using my lappy on battery power for a while, it will get down to maybe 15%-20% and then the battery will die without a low battery warning. I tried the battery calibrator that apple provided in one of the older updates but it said the battery was up to date. Any ideas whats wrong?

Thanks

Have you repaired permissions lately?
Have you tried it in another account on your computer?

I repair permissions pretty often so yes ive done that.

I havent tried another account tho...maybe ill give that a try.

Wait, are you saying you calibrated the battery like this? Maybe reset the PMU and then calibrate it again. If that doesn't work, then try re-seating the battery.

hey a similar problem have just struck me... today when I was travelling my macbook just died with no warning and about 30% battery left according to the battery meter in the menu...

did anyone find a good solution to this?

its not giving a warning because the indicator is telling it there is still loads left, and the warning is only set to come on at about 7%. you may want to try resetting the PRAM
