Idea #10597: Unique power management interface

As of hardy's current state, out of the box, my laptop gives me 1h30 hour of power. With proper power management setting that don't really slow down the system, I can squeeze out as far as 3h30 to 4h.

All the feature required for good power management are already part of ubuntu (Pwertop, lesswatt, laptop mode etc...) the big problem is that configuring those features takes ages and you end up having to change lots and lots of conf file that are working against each other.

For example, acpi and laptop mode both configure hard drive parameters.

I think that the gnome power management panel should take care of all this so we don't have to start modifying all those conf files. Therefor, there would be only one place to take care of power management and ubuntu would be able to compete with OSX and Windows powerwise.
