I would suggest you to update the BIOS and touchpad drivers on the system for issue resolution. Please enter your service tag # on the link below and click on ‘Get drivers and downloads’ then download the BIOS from BIOS section and touchpad driver from ‘Mouse, Keyboard & Input Devices’ section onto the system and install it.
