Hi @massimo81510
Check if the touchscreen has been disabled in Device Manager.
To get to Device Manager in Win10/11 press the Win key and the x key (both together) and click on the Device Manager link in the menu box that appears.
When in Device Manager, scroll down to ''Human Interface Devices'' → click on ''>'' to expand the list of devices → ***right click*** on ''HID-Compliant touch screen.''
''If it shows an option to ***enable device*** ''click on that and follow the prompts. Restart the laptop and check if the touchscreen works OK
