Hi mohannad2,

Here are some of the things you can try to fix the problem:

Step 1: Select the search box in the taskbar, enter device manager, and then select Device Manager in the search results.
Step 2: Select the arrow to the left of Human Interface Devices.
Step 3: Right-click HID-compliant touch screen, and then select Disable.
Step 4: Right-click HID-compliant touch screen, and then select Enable.

If this does not work. Try the next steps:

Step 1: Right-click HID-compliant touch screen, and then select Uninstall.
Step 2: Restart your Laptop. 

The laptop should automatically re-install the drivers for the touchscreen after the restart. 
If you are still having issues after these steps, you can try re-installing the chipset drivers from

If the touchscreen still does not work, you may need to call Lenovo Warranty Support and have the system serviced. 

Hope this helps.
