I have Dell Vostro 3501, with Intel(R) Core(TM) i3-1005G1 CPU @ 1.20GHz 1.19 GHz processor.
Can't locate option to disable adaptive brightness or contrast.
Experimented a lot with whatever solutions are offered online, seems now somehow the adaptiveness is not there on charging mode, but it is still there on battery more.
Extremely irritating. Please help.
