Flex 15 Win10 - Touch screen suddenly stopped working

My touch screen stopped working in early October without myself doing any changes that I'm aware of. The Windows Anniversary update came at that time and might be involved.

In the Device Manager, there is no touch screen under "Mice and other pointing devices". There is a "HID compatible touch screen" under HID, which I've tried to disable and to uninstall. It comes back after reboot, but still no function.

It could of course be a hardware problem, but it's usually not....

Press Windows+X and open Device Manager, go to Mouse and uninstall USB touchscreen.

Thanks for replying, but as I wrote in my post there is no touchscreen in that place. (It's on my computer called - translated from Swedish - "Mice and other pointing devices", but I assume it's the same as you mean by "Mouse"

Can you try to:

 

  1. Turn the computer OFF, press the One Key Recovery buttonand select BIOS Setup Utility
  2. On the BIOS screen, press F9 to load setup defaults and press F10 to save and exit.
  3. When you get back to Windows, try to recalibrate the Touchscreenand test.

 

Also. Go to -

Settings

PC Settings

General

Advanced Startup: Restart Now

Troubleshoot

Advanced Options

UEFI Firmware Settings

Restart

 

Update us how it goes.

Loading BIOS defaults: Problem persists. Same status in the Device Manager, no reaction on touch.

Recalibrate screen: The dialog box says that the laptop screen has "Full touch support in Windows" (translated), but there is no reaction when pushing the displayed cross.

Your 'restart' sequence placed me into the BIOS again. What do do there? I saved and exited, then restarted. Still no reaction on touch.
