    I have had my MPB for 3 months, and have been careful to calibrate the battery, keep an eye on things, etc. Lately it's been hovering around 85% health (which seemed low to me, but it still had a 3 hour charge, so I was good).

    Anyway, I've had two or three kernel panics this months, which has troubled me.

    Then today, I unplug my laptop after charging it for an hour or so -- and after 10 minutes, without warning, the thing dies. I didn't think it was the battery, so I try and turn it back on -- I hear the Mac OS X startup noise, HD sputtering, and then nothing. Tried it a few more times before it refused to come to life at all.

    I plugged it in and it works but then I unplug it and the thing dies. The charge-o-meter says "No batteries available."

    I checked out the system profiler, and it says there is no battery installed.

    So -- is this a MPB issue or a battery issue?

    seems like a dead battery to me, install coconut battery and see what it says about your battery.

    The computer doesn't even register that there is a battery installed. According to Coconut, I have no battery.

    My MBP battery died after about 2mos. Could leave it plugged in all night and as soon as I unplug it the thing died. Went to an Apple store and they gave me a new one on the spot.

    All I've done is leave it plugged in more than before. I used to drain the battery more often due to the convenience of just not having to plug it in to use.

    usually after about a year, one would want to get a new battery. Battery life after a year can drop by half or more. (i.e. Apple iPod batteries)

    9 months, i am assuming you have the CD version. The battery life was probably affected by heat.
