Yesterday morning I was using my laptop, I ran the battery until it went empty. Right as it was about to fall asleep I plugged it into AC power. At this point I left to go do some stuff. I came back to find that the AC power wasnt actually plugged into the wall, no big deal right? I just plugged it in. Funny thing is the computer wouldnt wake back up for about 5 mintues. I don't know if that is a problem, I assumed it would wake right back up with AC power but i'd never ran the battery that low before. Anyway onto the problem, The battery charged from 0-100% in about 15 mintues, but I only get like 30 minutes of battery life. I've tried rebooting, and even doing the key command on apples website to reset the power regulator thing. Didn't help at all. I downloaded Capacity Meter and it said my battery can only hold 10% of its capacity. This battery went from about 3.5 hours to 30 minutes in a matter of a few hours. Its a brand new 15" Powerbook that is not even a month old. I know I can probably just get it replaced with no hassles at the apple store, but I just want to make sure im not missing something obvious I can do to fix it. Short Version: All the sudden my battery can only hold a 30min charge when it could hold 3.5 hours a few hours ago.
