Comment 10 for bug 531190

I also found out that:

if I change the value for suspend from yes to no in /usr/share/polkit-1/actions/org.freedesktop.upower.policy

that I can unplug the power cable without problems (after 1 reboot)

but then the following occurs:

if I change the value for behaviour when I close my laptop screen from blank to hibernate

then when I unplug the power cable my laptop does suspend with the screen open.

For now I leave the option for closing the screen to blank and I can work with the cable unplugged without problems.

I don't know if this information is related to the bug but maybe it can help.

I also could change the settings for critical battery back to hibernate, wich I set to nothing as trying to work around the bug.
