Similar issue on Maverick at the moment. From bug 620414:

Something happened recently on my Toshiba Satellite A200 laptop running amd64 Maverick fully updated, and now Ubuntu thinks I'm on a desktop computer. I'm using the latest kernel in the repos, 2.6.35-16-generic.

The laptop has had no problems with the battery not being recognized before on previous version of Ubuntu. I haven't had time to do a fresh install to check if it's still present then.

This is what seems to be missing:

 - No "on battery" tab in Power Management (http://twitpic.com/2fkm53)
 - Battery icon will no longer display in the panel at all
 - No notifications related to battery whenever I unplug or plug in the power cord
 - No notifications anymore when I change the brightness using Fn + F6 / F7
 - Screen doesn't automatically dim when on battery

I'm having the same issue on an Alienware m11x. It seems to have started after a recent kernel update, and something odd I've noticed is that the battery info is now showing up under /proc/acpi/battery/BAT1 instead of /proc/acpi/battery/BAT0. Once I look at the info in /proc, then GUI utilities pick up the battery and start showing information again.

I'm using a Toshiba Satellite L655 and I'm having the same issue with Ubuntu 11.04. The battery isn't detected at all.

I have the same problem with a Latitude E6410 laptop using Arch Linux. I could switch to Ubuntu for testing if necessary, but I filed this bug upstream where I think it's better suited:
