Description of problem: In earlier versions of Fedora G-P-M would consider the cumulative power remaining in the system. Now with Fedora 11 G-P-M claims to be empty and throws all of the out of power alarms when the first battery is drained despite the fact that the second battery is ~96% full. Version-Release number of selected component (if applicable): gnome-power-manager-2.26.1-3.fc11.i586 This wasn't a problem with Fedora 9 at least, I didn't run Fedora 10 on this system long enough to notice if this issue was present there. How reproducible: Everytime Steps to Reproduce: 1. Get two batteries for your system. 2. Disconnect from the wall so that the system is on battery power. 3. Notice that Gnome-Power-Manager tries to shutdown your system when the first battery is drained, despite the second battery having plenty of power. Actual results: Being shutdown 2-4hrs early. Expected results: Being able to use both batteries. Additional info: Can be provided upon request.
