Steps to reproduce:
1. Have the laptop powered on
2. Plug it in to charger; the battery icon will indicate charging.
3. Put the laptop to sleep (e.g. close the lid)
4. Unplug charger
5. Wake laptop up

Expected behaviour:
- Battery indicator changes to reflect battery percentage.

Observed behaviour:
- "org_kde_powerdevil has closed unexpectedly"
- "Report bug" and "Restart application" options are not available
- Battery icon disappears
- Brightness control keys cease to function
- All power related settings display the following error:
'Power Management configuration module could not be loaded.
The Power Management Service appears not to be running.
This can be solved by starting or scheduling it inside "Startup and Shutdown"'

Workaround:
- Restart OS

Package version:
- extra/powerdevil 5.14.3-1 [plasma]

Device info:
- HP EliteBook 8570p
