GNOME Bugzilla – Bug 719948
Set to 0 brightness will turn off the birghtness

The machines ship with win8 have 101 levels of brightness, and the lowest one level will turn off the backlight. User can't see anything on the screen, so in this case, we should not set the brightness to 0. It won't be a problem on laptops, but on All-In-One machines. There is no way for users to move their mouse and adjust the brightness.
