Just recently I have run into a small (but a little troubling) problem with my battery on my IBM T42. I usually run my computer from the plugged in status and the battery meter on the computer will pretty much always read 100% capacity. Yesterday I unplugged my computer and ran it without a charge and the battery dropped down to 22% capacity. I left the computer plugged in over night and all of today and yet the battery still reads at 22% battery capacity. Is this a overheating problem or some other sort of problem? I am really not that good with computers and came across this site figuring someone might be able to help me, well thanks for reading.
