I'm hoping someone may have experience of an strange problem i'm having on a titanium powerbook. The battery is only charging up to 94% on the meter. Also the coloured led's in the charging cable are showing amber when charging is not taking place, and green when it is. I've sent the computer and charger to an authorised mac place, and they couldn't find anything wrong. I got it back the other day, and it was fine for a while before going back to its old behavior. Sometimes it charges, sometimes not. Could this be a problem with the mac or do i just need a new charger? Thanks for reading.
