Windows 10: Yoga 720-13ikb - no HID compliant Touch screen

We have issue with 3 x Yoga 720-13ikb out of box. No HID compliant touch screen visible under device manager and therefore no touch working. Did a factory reset without change. Installed windows stand alone copy, same issue. Did I read somethgin about usign older BIOS? How do I get hold of an older BIOS? Any other solution anyone knows about?

Lenovo Yoga 720 15IKB - Touchscreen Nonfunctional - Windows Updates

Greetings, y'all!



On 3/14/2020, I had two updates that were installed on my Lenovo Yoga 720 15IKB laptop:

• Feature update to Windows 10, version 1909 (hereafter "U1")
• 2020-03 Cumulative Update for Windows 10 Version 1903 for x64-based Systems (KB4551762) (hereafter "U2")

After installation of updates U1 and U2 and subsequent restart, touchscreen functionality was completely disabled.



I attempted the following methods of repair:



Update rollback:

• Rolled back update U1: Unsuccessful
• Rolled back update U2: Unsuccessful

Device Manager:

• Disabled and re-enabled device, "Human Interface Devices/HID-compliant touch screen": Unsuccessful
• Uninstalled and reinstalled drivers, "Human Interface Devices/HID-compliant touch screen": Unsuccessful

Boot:

• Started in Safe Mode: Unsuccessful

If anyone could provide additional suggestions/assistance, that would be greatly appreciated!
