Sometime in the last 24 hours the battery on my IBM Thinkpad T40 stopped charging. When I'm plugged in I can work just fine but the battery has run down so as soon as I lose AC power (i.e. unplug the laptop) it dies. I've tried re-booting as well as shutting the laptop off and removing and re-adding the battery. Nothing seems to help.
A couple of things did happen in the last couple of weeks that may have caused this:
1. A week ago or so I open up a cup near the laptop and a few drops of liquid found their way to the laptop. However, it was a very small amount of liquid and I don't think anything got inside the case so I doubt this caused it.
2. A few days ago the laptop feel off a low chair it was sitting on. It was in a padded case so I didn't think much of it (it fell no more than 12 inches) but potentially this could have caused it I guess.
My thought right now is to purchase a new longer-life battery for the laptop and see if that solves the problem. I've been thinking about doing that anyway so it wouldn't be a big deal. But before I did so I figured I would post here and see if anyone has any other suggestions.
