Have a Lenovo yoga 3 14'. Recently touchscreen stopped working out of the blue; went into my driver software and found out that the HID compliant touch screen device is 'not connected to the computer'. I'm running the latest Windows 10 and the drivers are completely up to date. Uninstalling the driver only hurt the cause as when I rebooted the computer the driver did not get reinstalled and I had to restore to a previous system version. Any help as to solving this issue would be greatly appreciated.
