all

Hello,
I recently received a used X41. The battery worked fine for the first day (at a
reduced capacity expected for it's age). Since then, it has not worked at all.
If unplug power from the wall, the computer is turns off instantly.
Oddly, Linux seems to reporting that everything is fine with the battery, as
shown below. I can accept if this is just a symptom that the battery needs to
be replace, but I wanted to check if there's something else I shouldn't be
considering. This is with Ubuntu Karmic Koala installed (along with the
KingSpec 32 GB SSD!)
