I have a different sort of problem with screen brihgtness.
In the Plan Brightness I have switched to full brightness for both battery and plugged-in mode. But when i unplug my laptop, the display dimmes itself and I have to mannualy adjust the brightness. Same thing happens when I plug-in the computer.
I have corrected every available pover plan to maximum brightness and I am running the maximum preformance power plan.
And an awkward thing happens when teh display gets dimmed, and I open the ADJUST DISPLAY BRIGHTNESS menu and I slide the brightness to a lower level, the display gains brightness...
