    08 MBP shuts off at 30% battery
    alright, my macbook pro was purchased in the summer of 08, and i would say i've taken pretty good care of it. I typically just use the computer on the charger, taking it off the charger and cycling the battery every couple days or so. However, over the last semester, I noticed a dramatic change in my battery's ability to hold a charge.

    so here's my problem...

    My laptop will shut off with no warning when the battery's charge gets around 30%, sometimes even 35 or 40%. I don't receive a low battery indicator or anything.

    Info (directly after booting back up from battery failure):
    Manufacturer: Sony
    Device name: ASMB012
    Full charge capacity (mAh): 2201
    Health Information:
    Cycle count: 241
    Condition: Check Battery
    Battery Installed: Yes
    Amperage (mA): 1517
    Voltage (mV): 12173

    so what should i do about this? i don't think i should have to buy a new battery after a year and a half of normal use.

    "condition: check battery"

    people always ignore this -_-

    go to apple, get a new battery for free. Its under warranty by sony. Be sure to have a genius appointment. I got my new battery the day i went in.

    dang, 241 cycles!
