Hi,
This is a patch to fix these:
https://bugs.launchpad.net/ubuntu/+source/devicekit-power/+bug/403303
https://bugs.launchpad.net/ubuntu/+source/gnome-power-manager/+bug/460631
https://bugzilla.redhat.com/show_bug.cgi?id=439460
http://ubuntuforums.org/showthread.php?t=1317434
https://bugs.launchpad.net/ubuntu/+source/devicekit-power/+bug/403303
This is a hardware bug. It could also be fixed at the ACPI level,
but having this fix here doesn't hurt.
Tested on Ubuntu 10.04 Desktop, 2.6.32-24-generic.
The patch is against upower 0.9.1-1
Regards,
