Batteries on stereo, at least their status

This is affecting my beloved T60p, it didn't happen when the laptop was running GNOME 3.
It shows the status of two batteries.

It shows up when you mouse over or make a right click on the battery icon on the Panel.
Doesn't seem to be having any other issue... The laptop suspends (and back) A Ok, and the battery life looks just about what to be expected from the laptop.
