Ok, so I've had my Macbook Pro for about 2 months now... I usually keep it connected via power adapter becasue I use an external monitor... and it's on a lot... when I took it to class, i noticed it said 45 minutes left on full charge... i was like wtf?!?!.. so then i downloaded cocunut battery and it said maxiumum capacity was 1155 mAh and that was a week ago... now today... it says maximum capacity is 13 mAh... WTF?!?!... will calibrating the battery fix this? (i doubt it)... i don't have applecare = ( ... i guess i will have to get it right?
