Hi, my Asus Q302 convertible laptop worked fine until yesterday I installed windows updates restarted and immediately afterwards , the touch screen stopped working. I have tried uninstalling the update and restoring the computer to a time point on Friday, both without success. The computer consistently says there is no touch or pen device available, and there is no "HID-compliant Touch Screen" under HID in Device Manager. What can I do to bring the touch screen back? Thanks.
