Keyboard backlight in Inspiron 15-5559

Hello group,

I'm having trouble turning off the keyboard backlight in my Dell Inspiron 15-5559 with windows 10. All the self-help sites tell me to go to windows mobility center and do it from there, but there's no keyboard option in mobility center. Also, the backlight will sometimes go on and off all by itself when I'm not even touching the laptop. Am I missing a driver or something?

Thanx,
