Description Tom Kijas 2012-07-19 17:27:23 UTC
Hi, I try KDE4,9 and I fond it cannot read my battery state. It can read it after I login to KDE and can read (un)plugging AC, but cannot read the change of battery state.
Comment 1 Tom Kijas 2012-07-19 17:55:36 UTC
It seems the detection just stops to work after some time....
output from "qdbus --system org.freedesktop.UPower /org/freedesktop/UPower/devices/battery_BAT0 org.freedesktop.UPower.Device.Percentage" when the detection is OK:
97.7599738391105

And the detections stops just right in the moment I plugin AC power.:

96.3374754741661... etc.

stats in /proc/acpi/battery/BAT0/state are changing...:
tomas@tom-MacBookAir:~/Dokumenty$ cat /proc/acpi/battery/BAT0/state
present:                 yes
capacity state:          ok
charging state:          discharging
present rate:            28787 mW
remaining capacity:      58760 mWh
present voltage:         8091 mV
