May I ask, did You use Windows on this unit before moving on to Ubuntu?
If yes, did the battery monitor work as expected in Windows?
The reason for asking is that I believe there is a BIOS bug existing for the L650-series that causes the battery to not charge under certain conditions.
Such an issue may cause strange effects in the Gnome power manager in Ubuntu.

Hmm...maybe I am mistaking. Looking at the model number of your unit and comparing with the BIOS revision information stated on Toshiba.com (seems to be the same BIOS'es for a similar model) there are no fixes for battery charging there.
So maybe I am misleading You here.
Anyway, still it is interesting to know if the battery monitoring was working properly in Windows.
