Hello,
I have E6530 laptop with Windows 8.1. I have a problem with screen brightness. Screen is adjusting the brightness automatically almost all the time up and down. Not much, but enough that I notice it and it's disturbing. Doesn't matter if it's plugged in or using battery.
I tried to disable ambient light sensor (cannot find any setting in bios for this) and I have also disabled Windows 8.1 adaptive brightness.
Any ideas?
