[SOLVED] Remaining battery charge way off when resuming from suspend

This has been bugging me for a while now.  When I resume from suspend, more often than not my battery level is reported as critical by xfce4-power-manager (I now use gnome-power-manager, and it's been giving me the same problem).  Sometimes it will correct itself within a few minutes, but most of the time it doesn't.

Restarting the power manager doesn't do anything, restarting X doesn't do anything.

The acpi command always seems to report the correct battery life:

If there's some command to refresh whatever these power managers are reading from, I could just add it to a hook in /etc/pm/sleep.d ...

I think the next time this comes up, I'll try restarting upowerd ... if that works, I could make a hook for it.

This seems to have done the trick:

/etc/pm/sleep.d/10-upowerd

#!/bin/bash

case $1 in
  resume | thaw)
    UPOWERD=/usr/lib/upower/upowerd

    /usr/bin/killall -9 ${UPOWERD}
    ${UPOWERD} &
  ;;
esac
