Hello

I am writing to you concerning acer batteries.
My laptop batteries aren't detected until I plug in/out the ac_adaptator.
If I am at home, working on it, no problem. But if I am out of buildings,=20
where I can't have power, my power status won't be detected by my desktop=20
environnement.

In fact, sysfs detect it at boot and display it's state. But kde seems to l=
ook=20
at udev event :
=2Dwhen I switch off udev service, and plug in or out my adaptator, kde det=
ect=20
nothing !
=2D if I start again udev (just after stopping it and plug in/out adaptator=
),=20
kde detect it !

When I look at events in boot, I can see that my battery is detect by udev :
