I reinstalled Windows 10 and had this issue. Here's what an ASUS rep told me to do and after trying everything on the internet (troubleshoot hardware issues, windows update, see hidden contents in device manager), the following solution was the only one
that worked:
Please do the following steps to Reset the BIOS:
Step 1: Please turn off the unit completely.
Step 2: Please turn the unit on and quickly press the F2 key on the keyboard to enter the BIOS.
Step 3: Please press the F9 key in the BIOS to load optimized defaults and select yes to confirm.
Step 4: Please press the F10 key to save and exit.
If those steps fails, attempt a System Reset:
Please do the following steps to Reset the system:
Step 1: Please press the WINDOWS key and the letter I.
Step 2: Please select Settings.
Step 3: Please select Update and Security then Recovery and select "Reset the PC".
Step 4: Select okay and allow the Reset process to run.
You will have to keep the unit plugged in during the process. You will select the options to 'Remove everything', 'Only the drive where Windows is installed', and 'Just remove my files' if prompted.
Ensure that all data is backed up.
I chose the "keep my files" options but remove all apps. This reloaded everything and the only thing I had to add was Asus Smart Gestures for touch pad scrolling.
I can attest that the System Reset method restored my Touch Screen. My laptop have been sidelined for almost half a year because of the inoperable touch screen and last weekend, I decided to do a System Reset thinking that by this time, I don't need any
of my files in the laptop. This would be the last step before deciding to replace the touch screen hardware. To my surprise, I got back by Touch Screen. Now, I am going to be careful about loading any power management app which I think caused all of this.
