    My cousin was on my UMBPro the other night. When I went back into the room to see what he was up to he said the laptop just turned off.

    The battery was fully drained to the point the computer powered off...

    Is this bad for my battery life span or does 1 time not really matter? I plugged it in right away and let it fully charge.

    My battery has been fully drained approximately 50+ times and well:

    In fact completely draining it is part of the calibration procedure.

    Looks like iStat pro. Unfortunately, my battery's picture of health does not look nearly so good. Despite running the calibration procedure a few times this weekend, the battery in my 5-month old 15" MacBook Pro machine doesn't want to come back to life.

    Anyone have an idea of how to best proceed with results like those shown in the picture below?

    I'd take it into Apple, that's insane.

    Killing the battery "completely" is part of the calibration process!! I don't think it's possible to totally kill the new batteries as you described since they have circuity to prevent total discharge.

    I had the same issue, with 12 cycles on the battery. Solution is calibrate it, then use the battery. Battery capacity is still increasing with 20 cycles on it.
