Noticed something strange when I was unable to turn on my Touchpad using the F9 key.
When the key didn't work, I went looking for the device in Device Manager. It is not there. Also, not appearing on my search. Installed the latest Touchpad software earlier today and restarted the laptop. Same situation - it seems the Touchpad has ceased to exist anywhere on my system.
System: Win 10 64bit
Please enter safe mode to check if the problem persists.
If the problem persists, there may be a problem with the hardware of the touchpad, please contact ASUS repair center in the country of your residence: https://www.asus.com/support/Service-Center-All-Countries/
Sorry for any inconvenience it may be caused.
