[Bug 61065] Guidance Power Manager won't detect battery

[BenjaminKoenig]

Public bug reported:

Binary package hint: kde-guidance

On my Laptop the guidance-power-manager is not working correctly anymore because system.formfactor is not set to "laptop". 
I got it starting by changing powermanage.py:

return properties["system.formfactor"] == "laptop"

to:
return properties["system.formfactor"] == "laptop" or properties["system.formfactor"] == "unknown"

but when I start guidance-power-manager i still get errors:

<qt.QImage object at 0xb51fc1ec>
<qt.QImage object at 0xb51fc1ec>
No battery found.
No battery found.
No battery found.

when I run hal-device | grep battery I get nothing at all.
