    My Macbook has been working flawlessly for almost 2 years and then yesterday it won't work on battery power. It works fine when on AC power, but dies in about 2 seconds if I remove the ac plug. OSX says the battery is fully charged, and the lights on the battery say its full as well.

    I have reset the SMC, but haven't been able to run the hardware test because I don't have my install dvd with me.

    I know the number of cycles is high, but the mAh is still good correct?

    Maybe try resetting PRAM? Have you removed/reinserted the battery?

    I'm not sure, but the battery might be dead. Does it show an X on the battery status menu?

    This same thing happened to me (except mine was less then a year old, about 6 months) so your lucky at least you used yours for 2 years. I got it replaced for free when i took my computer back to bestbuy because of a harddrive failure.

    i had that happen to me as well after 2 years

    thought my computer died as it would just shut off on batt

    turned out the batt was bulging and got a new batt and its all working good now

    Tried the pram, no luck.

    Took the battery out and put it back in, multiple times...no luck.

    It does not have an X in the icon, it says charged and everything looks perfectly normal.

    The only thing I cant figure out is that it was working perfectly 2 days ago. Battery was still lasting over 3 hours. Do they just go out like this? Or could it be something else?
