Ask iBAM: Powerbook Battery Issues

10 years ago in Ask iBAM by Brent | 2 Comments

Fellow iBAM community member Ken, is having some issues with his Powerbook battery and sent me a quiestion for Ask iBAM. Here’s his question:

I have a powerbook G4, info below, and wanted to see if there was something I’m doing wrong to cause my battery problems. I bought a new battery because I thought the last one was getting old and causing the symptoms: no matter how many times I calibrate, it won’t charge past 43 or so percent. So, I’m having the exact same issues with the new battery. I’ve tried to reset the pram and the power management thing, but no luck.

Any ideas???

Thanks for any help.
