    My MBP is 25 months old and according to the stats in my attached picture Its an ok charge.
    The Question I have is that when my computer reaches 39% capacity it shuts off completely. I check the battery under the machine and it's dead. If there anything I can do to fix this.
    I can't cycle the machine anymore and I still have 1 year left on my Apple care plan.

    Edit: I can't re-calibrate the machine due to it shutting down at 39% left. It just shuts down completely. I've tried it a number of time to no avail.

    If your battery just dies at 39%, you have a dead cell in the Li-Ion pack. This will require a replacement battery. There are ways of bringing it back, but it's not practical.

    Not necessarily. A battery calibration will see if the battery is really dead or not.

    Call Applecare, but your cycle count is over 300, so I'm not sure if they'll cover it.
    I wouldn't take no for an answer though.

    but how can I do a calibration if the computer won't run to zero? I try to let it run down but it just shuts off.

    I have an appointment on Wednesday with Apple Care.

    Leaving it off for a few hours after it shuts off will do the trick.
