Upower not seeing my battery

[Geoff Buchan]

Hi all -

I've upgraded my laptop to a newer Ubuntu release which is using Upower,
but this apparently doesn't see my battery.

System level symptoms are no battery tab in the gnome-power-preferences,
not seeing a power applet in the taskbar, etc.

I can force a suspend to RAM, which works, but I think the root cause is
that something in my configuration isn't working with Upower.

I'm seeing the following from running upower -d:
Device: /org/freedesktop/UPower/devices/line_power_AC

Any ideas what I should check to investigate further?
