My computer has 85% battery but won't stay on without an adapter plugged in.  When plugged in, it says it has 84% battery and stays at that percentage.  It then reads that it will take 20 hours to charge.  Please if anyone knows anything I can do be much appreciated.

MacBook (13-inch Mid 2009), Mac OS X (10.6.8)

    Go to the Apple in the upper left corner and select About This Mac, then click on More Info, then select Power from the left hand column of the System Profiler. Copy and paste the Battery Information back here.

    Provided that the battery is indeed good, you may have a bad contact somewhere which, in practise, means you cannot use your mac otherwise than plugged in.

    REmove you battery and test it in another, similar mac. If it works there, the problem is inside your mac. If it dos not work either, the problem is with your battery. Put another reportedly good battery in your mac, if it works, it is all clear.
