Fedora Needs Help Testing Power Management
Today is the Fedora 15 Power Management Test Day. They're looking to see how well power management is working out on their updated Linux stack on a wide range of hardware, which is why they're seeking the help of as many people as possible. Even if you're not a normal Fedora user, this work may still help out your distribution due to upstream contributions and fixes by Red Hat developers. Testing can also be done from their updated LiveCD so this will not affect any other Linux installations as well.
Simply fire up the LiveCD and see how well the power management is working. If you wish, the PowerTOP data can be submitted too.
Suspend-and-resume and the overall Linux power management support has improved a great deal compared to years past, but proper support across as much hardware as possible is becoming more important due to the controversial GNOME 3.0 change that will suspend your notebook/netbook by default on the screen being closed (assuming no external displays are connected) without providing an easy UI option to disable that "feature."
