After my laptop has been on a while, the screen inexplicably darkens. It doesn’t go completely dark, but dims to the point that I can barely discern the screen. This happens whether or not I’m active/using the OS, and whether or not the laptop is plugged in. Moving my mouse around or adjusting the brightness from the keyboard has no effect – I have to reboot in order to reset it to regular brightness.
I’ve gone into power settings and turned off “Dim screen when inactive,” set Blank Screen to “never,” turned off Automatic Suspend. None of that has fixed the issue.
Anyone know what might be going on?
