I've had this laptop for around 2-3 years, and it's been going on for as long as I can remember. The backlight/lighting would keep going down. At least before, I'd be able to readjust it back to normal, but for the past couple days I've been unable to do so. I tried restarting-- nothing. I think this was after the laptop upgraded itself to Windows 8.1?
I'm not really much of a tech person. Anyone have any idea what I can do?
This dark lighting is straining my eyes.
