Lately my FN key has stopped working after a reboot, I find this quite annoying cause I have disabled the led backlight on my G75s keyboard and disabled the touchpad.
Well, it seems like theres a program thats not starting or crashing the HControl.exe. My solution is just starting that program again. It can usually be found in:
C:\Program Files (x86)\ASUS\ATK Package\ATK Hotkey\HControl.exe
To fix it, just hit start, and paste the above line and run it. Then it’s working!
