The Touchscreen Suddenly Stopped working!! - Lenovo Flex 4 Signature Series

Nothing different happened between turning off the computer & turning it on to keep working & yet all of a sudden the touchscreen doesn't work?? 

It's almost as if it was turned off? Is that a setting that can be turned off or does this need to be fixed or something? 

 

So annoying!!

Hi, AJWalts    -

 

Thank you for writing in to the Lenovo Forum - happy to have you here today.

 

- Press Windows+X.

- Select Device Manager.

- Find the Touchscreen driver under Mice and Other Pointing Devices>USB Touchscreen Controller(A111).  You're going to uninstall this and check the box that says "Delete the driver software for this device".  Don't worry, it won't blow up your computer.

- Restart your computer.

- Re-open the Device Manager, and confirm that the Touchscreen is now listed under Human Interface Devices.  Your issue should be resolved!

 

Update us how it goes.
