There's no touchpad settings anywhere on my laptop, not in device manager or anywhere else and Asus Smart Gesture installation always fails. There's a 'disable touchpad' option (fn + f9), but it doesn't respond at all, so I assume that there's no touchpad so disable.
I have been experiencing the same issue. I have TWO laptops Asus Notebook UX306U. Both started to have the issue mid-July 2018, I believe after a windows 10 update. I have tried everything from updating all drivers, BIOS, etc. to factory reset, and still the problem persists.
Thanks @jayeff, finally I fixed the problem by finding a more up to date driver for the touchpad than the one given by asus.com or tech support. It's ridiculous that the driver they offer is obsolete. They gave me v06 when v25 is out...
Great solution. Worked for me! I tried downloading a driver and that did not work. I just followed your BIOS toggle method, and it worked for me! Easy fix. When I first checked the BIOS, it indicated the INternal Pointing Device was Enabled, So I disabled it and restarted. Then I went through the reboot and changed the BIOS the second time to Enabled, and when I restarted my laptop the pointing touchpad worked! You are great!!!!!!!!!! Thanks for your post.
