Description Weng Xuetian 2012-09-17 12:42:25 UTC 
If I set lightness to lowest level, it will be the highest when unplug the ac power.
But if I set it to "a little bit higher" than the lowest, it will work.

Reproducible: Always

Steps to Reproduce:
1. Open battery profile
2. Set lightness to lowest (move the bar to the left most)
3. And unplug
Actual Results:  
The lightness will not change.

Expected Results:  
The lightness change to lowest.

Seems that if you set the brightness slider to zero, KConfigGroup will ignore the settings since it thinks 0 = nothing set and falls back to the default 50.
