Why won't my Macbook Air charge past 79%?

HELP! I've only had my Macbook Air 13" (late 2010) 10 weeks. For the last couple of weeks when I've charged it up, it won't go past 79% - anyone have any ideas why?

MacBook Air, Mac OS X (10.6.7)

Hello,

have you tried to recalibrate the battery for the unit. this should resolve the issue for you.

You can try the following article to recalibrate the battery on the unit:

Calibrating your computer's battery for best performance

If the issue still persists, you can take the unit to an Apple Service center they can get this repaired under warranty.

Peace.... 🙂

Thanks for the reply and link - to calibrate though, it must be charged to 100%, but it's stuck on 79!!

Hi fayeh21,

If you run the battery down to 0% and recharge it, the battery display always a maximum of 79%? In System Profiler under battery what does the battery's full charge capacity read?
