Hello fivedezs,
Do you mean pressing FN+F9 does not work? was there any pop-up when you press it?
How about other function key? do they work?
Thank you.

The other function keys work fine but nothing happens with F9. I've seen posts where this seems to be a common issue but none of the fixes have worked for me yet. I looked up Asus Smart Gesture and tried repairing and reinstalling. I tried going on to the files and troubleshooting the settings. I tried just going into the touch pad settings and canted disable it there either. I'm missing something here.

Hello fivedezs,
Please reinstall the ATK package first, then reinstall the ASUS Smart Gesture (Touchpad Driver)
Q503 Driver & Tools | Laptops | ASUS USAThank you.

I reinstalled both, also changing the recommended setting for each file but I'm still missing a step because I can't get it to work...
