For the past few days, the battery charge monitor applet up in the notification area has been showing an all white icon at 0% charged, even though it has been connected to the AC power consistently. Hovering my mouse brings up the tooltip balloon which shows either:

Computer is running on AC power
Laptop battery charging (0%)
Battery charge time is currently unknown

or

Computer is running on battery power
Laptop battery discharging (0%)
Battery charge time is currently unknown

This problem persisted through multiple reboots and I finally got sick of it. I did some research and read through several bug reports before the obvious solution just donned on me. I shut down the computer, pull the battery and reseat it, boot up on battery power (AC adapter not hooked up), and there it is with the green charging battery icon at 89% charged. Now my tooltip balloon correctly shows:

Computer is running on battery power
Laptop battery 2 hours 15 minutes remaining (89%)
Battery discharge time is estimated
