This morning I had some ominous occurrences with my Mac Book Pro.  When I got it out, the battery was quite warm, even though I had turned it off last night before connecting it to the charger.  (It's never warm when it's not using the battery.)  Then, when I pushed the power button, nothing happened until after several pushes.  Eventually it did start up and seems to be working OK, but I'm worried, could this be a sign of a problem?  I lost a hard drive a few years and don't want to repeat that trauma.  Any ideas?  Thanks!

    At the very least, I'd run an Apple Hardware Test and see if it picks something up. Try resetting the SMC too, as power seems to be involved in the issue.

    I would not expect the battery to be warm after charging overnight while the machine was powered down, though. Even if the battery was absolutely empty when you plugged it in, it should have completed a charge well before you got up this morning (unless it was a very short night's sleep) and had a chance to cool off from any heating that might have occurred during the charging process. So it probably wouldn't be a bad idea to get it checked out by Apple.

     

    Is this an original battery? If not, how old is it?

     

    One precaution you should definitely take, just in case there is some kind of hardware issue, is to be sure you are backing up your computer frequently.

    It is an original battery.

     

    That may be part of the problem, then. 4 years is an awfully long time in terms of laptop battery lifetime.

     

    Try this: open System Profiler (or System Information if you are running Mac OS X 10.7 or later), found in /Applications/Utilities. Under Hardware in the left-hand list, select Power. What does the battery information show?

    That's not a terribly high cycle count, and the condition reports as "normal," so there's not an obvious problem with the battery.

    Odd. Did you change the internal drive sometime within the Mac's lifetime?

     

    Since the Early 2008 models, the AHT has been residing in a hidden corner of the hard drive; I recall having a bet with my local AASP who insisted that the DVD was needed and lost when I ran the AHT without optical media on my now-dead Early 2008 MBP. If you changed drives or did a low-level format, you would of course lose the AHT copy and would have to resort to DVD 1.

     

    Just to cover all bases, since yours has a removable battery, have you taken it out and verified it is not swelling?

    Well, as I said, there's not an obvious problem with the battery, but as old as it is plus with the heat issue you saw, it's probably wise to get it checked out by Apple anyway. Otherwise, if it's not giving you any trouble, shows no signs of swelling and still lasts reasonably well when you use the machine unplugged, I wouldn't bother replacing it just yet. Keep an eye on it, though.
