Hi I'm new round here, I have a G4 Tit. Powerbook and have had it for 6 months now. I usually work on the powerbook with the power adapter connected to it all the time, I also tend to put the powerbook to sleep only and not really shut it down. However, recently I have noticed that the battery/power bar on the top right hand of the screen only would show 98% and then it went down a few days ago to 97%. It would never go back to 100 or would it be fully on 100% as it was before. And this is when my powerbook is connected to the mains and not running off battery power. Can someone explain to me why this is, or does anyone have this exact same issue? Is it even an issue worth worrying about? Any help or info would be appreciated, thanks!
