Comment 35 for bug 481312

If I kill gnome-power-manager it does not happen.

Without gnome-power-manager:
1. boot without a/c
2. login
3. plug in a/c
4. screen stays dim, does not suspend. No popups.

with gnome-power-manager
1. boot without a/c
2. login
3. plug in a/c
4. screen goes bright
4a. popup (battery charging; will take X minutes) (sometimes too slow)
5. suspends (takes a minute)
6. type on keyboard
7. un-suspends
8. screen is locked by screensaver

Further a/c connect/disconnect:
* no suspend.
* popups about battery charging working as expected.
* The screen does not dim.

The desktop knows the cable is unplugged, because I get popups, but it doesn't take any action. When battery power gets very low it shuts down.

The suspends are immediate. This is annoying when you've got powercuts or accidentally trip the cable.
