Latitude E6420 100% Brightness But Screen Is Still Dark
I have windows 10 installed on my laptop
This is not a problem I have had before
I have to shine a flashlight at my computer screen in order to see anything. When I open the display settings, it says my brightness is already at 100%, and nothing changes when I drag the slider, or when I plug it in. The brightness won't change when using the Fn key either. I tried disabling and re-enabling the display adapter and that didn't work either. I have also tried restarting my computer but again nothing changed. I don't know what could have caused this to happen; I've had this computer for a year and have never experienced this.
Any help to fix this problem would be appreciated!
