Brightness key not working on Dell Inspiron 5459
The brightness keys on my laptop are not working. When I click on the F12 key, it shows on the bar that it's increasing, but my screen's brightness is actually not increasing/decreasing. I've tried several methods, but nothing seems to work.
pls help
