Power Indicator says battery is empty when it's full

Binary package hint: gnome-power-manager

the power indicator in Natty on my Thinkpad x201 says the battery is empty, even though it's full.

Basically, when I plug the Thinkpad in, the indicator correctly displays the battery/lightning bolt indicating that the battery is charging. When I unplug the power brick, the battery indicator shows the red battery outline indicating an empty battery. The indicator messages say Remaining Time Unknown, but if I click on the icon it says I have over 3 hours of battery life left.

This did not happen after I initially upgraded to Natty from Maverick, but seems to have happened after a previous Natty update.
