decrease spurious wakeups by the battery applet on my 4 core server none

Description Arjan van de Ven 2006-08-31 22:07:57 UTC 
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

Comment 2 Matthias Clasen 2006-09-01 17:05:28 UTC 
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.
Comment 3 Matthias Clasen 2006-09-01 18:08:26 UTC 
I've made it 5 seconds/10 seconds.
Fixed in 2.15.90-6.fc6
Comment 4 Ray Strode [halfline] 2006-09-05 14:44:58 UTC 
For fc7 we really need to drop that applet.  it is completely redundant with
gnome-power-manager
