That generally means that the computer has determined the battery is bad, and that it can't charge the battery, or draw power from it. I'd download Coconut Battery: http://www.versiontracker.com/dyn/moreinfo/macosx/27425 This will tell you the capacity of your battery, load cycles, if it's charging, etc., and generally give you a clearer idea of what's going on.

Try a friend's battery with your computer in order to confirm this.
