Hi,
Please do try to uninstall/reinstall the touchpad driver.
- Go to Device Manager and uninstall the Synaptics Touchpad driver.
- Once uninstalled, download and install the latest driver.
- Here's the link:

- Reboot the laptop once the latest driver has been installed.
- After the reboot do test it again and see if the same problem will persist or not.
