Hi Ameya1101.

Welcome to the community.

Apologies for the troubles that you're having with the laptop's touchscreen. When was the last time that the machine works properly? Did you install any updates or software prior experiencing this problem?

Please try to reinstall the touch screen driver: Go to Device Manager > Human Interface Devices > HID-compliant touch screen. Right-click on it and select Uninstall device. Then restart your laptop. Windows will automatically reinstall the driver.

If same problem, please check if the touchscreen functionality of your laptop works outside Windows. To access the recovery environment, press and hold down the shift key then restart your laptop. Once you successfully accessed the recovery environment, try to test the touchscreen to select any options. 

Let us know how it goes.

Just sharing. I'm using a C640-81UE yoga, ever since the windows 11 update in November 2023, the touchscreen is not functioning. I have tried all of the suggested solutions, finally the safe mode function helps!

The touch screen is not working at first in the safe mode. After choosing to revert the last quality update of windows, the touch screen is back working immediately in the safe mode. It still works after a few restarting. This was corrected in Dec23 and after some regular Windows update in Jan 24, the touchscreen is still functioning. 

Thank you for sharing your experience. It's great to read that you were able to resolve the touchscreen issue on your C640-81UE Yoga by reverting the last quality update of Windows in safe mode. Your solution might be helpful to other users experiencing the same problem.

Best regards,
