Keyboard back light won't stay off.
I have an ASUS Q502L laptop. How do I make the back light on the keyboard stay OFF? I have to hit fn 3 about 20 times a day.

In the bios search for legacy usb support (or lus or something like that) and enable it

I'm sorry, I don't understand what you mean by the bios search.
