Hi all, Recently I stared having problems with my iBook G4 800 when running on battery power. All is fine and then the power is around 40% left the computer will just go to sleep. No warning or anything. Then you can't wake it up. If you plug it back in it wakes up and shows the battery at 1%. Then it continues to charge back to 100%. I bought a new battery thinking the battery I had was defective, but that didn't help. Any suggestions? Thanks.
