I have a MacBook (2 GHz Intel Core Duo) that's about 3 years old. Lately I've had absurdly short battery life. Today I took it to a cafe. It was fully charged up, and I started it up fresh. I worked for about 45 minutes with two applications open (Safari and MS Word), and it suddenly did a hard shutdown. It didn't even give me any warning or go to sleep -- just the shutdown. The battery percentage was at about 75 or 80%.
I've already taken it to the Genius Bar and they did a quick diagnostic and said my battery is normal. (They gave me coconutbattery.) I've tried the battery calibration, and it usually results in the same hard shutdown. The fan has not been running very often, and the system doesn't seem too taxed. I have no idea what the problem could be. Any ideas would be appreciated. (Hopefully I'm not looking at a new battery...)
Thanks!
