Hi, I'm happy to say that recently I purchased a 17'' MBP. It's my first mac in years, things have changed a lot but I'm glad to back so as to speak. I'm having trouble with my battery however, maybe... I've had the computer about 2weeks and have charged it everyday almost, but haven't run it down past 50% on any one time I don't think. The battery status information in will only indicate the percentage power left, and leaves 'calculating...' when I select time. For the past couple of days when I checked, the time indicated was 5hrs even though the percentage was at 90%. I got the 17'' MBP partly because of it's advertised battery life of 8hrs. What's going on? Any help would be appreciated.
