Description of problem:
the battery applet polls battery status every second, even on a server. This
frequent polling is eating power and is hurting with tickless-idle kernels
(there are many things on the desktop doing once or a few times per second
things, they add up to MANY, distroying power savings).
The attached patch uses a 10 second rather than a 1 second delay if there is no
batter present and we're on AC. 10 seconds is still respectable, but it reduces
the wakeups by a factor of 10

decrease spurious wakeups by the battery applet on my 4 core server
is there any point in polling the battery status every second, even on a laptop ?
every 10 seconds sounds totally fine to me, in general.
I've made it 5 seconds/10 seconds.
Fixed in 2.15.90-6.fc6
For fc7 we really need to drop that applet. it is completely redundant with
