- If it does uninstall/reinstall the Touchpad driver.
- Go to Device Manager and uninstall the Touchpad driver.
- Once done reboot your laptop and it should reinstall the driver automatically.
- After the reboot, do test it again and see if the same problem will persist or not.

- If all these will not work your last option would be to reinstall Windows.
