Hi i need help..i have a vivobook s410un.

The keyboard backlight is not working when i press fn+f3 or fn+f4. Other function like increase decrease screen brightness, volume, airplane mode, enabling touchpad, are working. Pressing the f3 & f4 button (without fn) still works too. Just the keyboard backlight function that doesnt work.

I tried:

  • restarting the laptop
  • plug & unplug the power (just in case power was the cause)
  • installing newest ATK package from asus
  • run HControl.exe

However, still not working. What could be the cause & how to fox it? Any help would be greatly appreciated..
