[QUOTE="ToddG, post: 351541, member: 23228"] (1) It's possible your computer didn't go to sleep when you closed the lid. I've had that happen twice in about four months, and it kills the battery. (2) [url=http://docs.info.apple.com/article.html?artnum=86284]Calibrate your battery[/url] before trying to figure out what Coconut is telling you. (3) Once you've calibrated the battery, run the computer on battery power for a while and see how accurate the battery meter's prediction is (if it says you had 4 hours of power when you start and after an hour you're around 3 hours left, for example).
