My computer seems to use no power at all when on AC, or so gnome-power-manager wants me to believe. Richard said that this might be the kernel using '0' when it means 'no idea'.
Can you try the rawhide gnome-power-manager rpm here pls: http://people.freedesktop.org/~hughsient/fedora/9/i386/ Thanks.
I would, but error: unpacking of archive failed on file /usr/share/gnome-power-manager/gpm-suspend-failure.wav;4808cc8a: cpio: MD5 sum mismatch gpk-install-file did not warn me about that, btw
Changing version to '9' as part of upcoming Fedora 9 GA. More information and reason for this action is here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping

Right, if you are on AC power and your battery is fully charged, then we can't get any power information from the battery at all. You can't represent "no data" in this version of g-p-m, although I'm made sure this is possible in DeviceKit power, and the next version of gnome-power-manager.
