What Happened

I usually work with my laptop close and conected to my monitor with HDMI. Before I close the laptop the brightness is setted on 50% (Exmple), but after close the laptop and open again the laptop brightness change to 0.

The bug happens because after close the laptop with HDMI connected the brightness change to (-1) and the brightness scale change the value.

Expected Behavior

Keep the same brightness after re-open laptop with HDMI connected.
