I have a 17" powerbook and i noticed that if the battery was 94%-100% full, then it won't charge..it just says that it's fully charged no matter if it's 99% or 95 %.. i have to let the battery gets less than 94%, then i will start charging til it reaches 100. i calibrated the battery many times, but it didn't help.. Anyone have any idea how to solve this problem...does that mean something is wrong with the battery..i have 10.2.6
