Since I updatet to kpowersave-0.7.3, the desktop applet shows me wrong remaining battery status. For example it slowly goes down to 50%, just for suddenly jumping down to 5% capacity. Normaly the battery is short befor running out of power then. Other tools like acpitool report correct capacitys. I use sys-apps/hal-0.5.10 compiled with apm-USE flag. kpowersave gives me this error messages, when being startet manually: kpowersave: WARNING: Unknown error while aquire org.freedesktop.Policy.Power

I guess this is an upstream bug. You should report it to developers
Take a look at bug #219431
Sorry it was bug #253776
sys-power/kpowersave removal, see bug #292799 for reference
