Comment 7 for bug 552597

Description of problem:

There is no "Running on Battery" tab on gnome-power-preferences; all settings work as if the computer was always plugged in, and the icon on the notification area is always of a plugged-in computer, with no charge information. When the battery gets too low, the computer just shuts down without warning.

I'm marking it as a g-p-m bug because other programs see the battery just fine. PowerDevil under KDE gives me all options for the battery, as does xfce4-power-manager.

/proc/apm shows the battery status:
$ cat /proc/apm
1.13 1.2 0x02 0x00 0x00 0x01 97% 61 min

hal sees it just fine:
$ lshal |grep battery
udi = '/org/freedesktop/Hal/devices/pmu_battery_0_0'
  battery.charge_level.current = 2048 (0x800) (int)
  battery.charge_level.design = 2126 (0x84e) (int)
  battery.charge_level.last_full = 2126 (0x84e) (int)
  battery.charge_level.percentage = 96 (0x60) (int)
  battery.charge_level.rate = 0 (0x0) (int)
  battery.is_rechargeable = true (bool)
  battery.present = true (bool)
  battery.rechargeable.is_charging = false (bool)
  battery.rechargeable.is_discharging = true (bool)
  battery.remaining_time = 4096 (0x1000) (int)
  battery.technology = 'unknown' (string)
  battery.type = 'primary' (string)
  info.capabilities = {'battery'} (string list)
  info.category = 'battery' (string)
  info.udi = '/org/freedesktop/Hal/devices/pmu_battery_0_0' (string)
  linux.pmu_path = '/proc/pmu/battery_0' (string)
