View Full Version : Powerbook Randomly shuts off

Jan 3, 2008, 01:53 PM
Whenever I have my Powerbook disconnected from the power source, it will shut off when the battery runs down to around 75% or so. I'll have to plug it back in in order to get it to turn back on and the computer will act like it ran out of power completely even though the indicator will show me at 75% or so and there will be 2-3 green lights left on the battery itself.

Any ideas what the problem is?

Have you calibrated the battery recently?

No, how do I do that?

I think you might just need a new battery.
