Thank you for using the Community Forum.
I have checked our product knowledge base and did not find a solution for this specific issue.
I would recommend since it is the touchpad to call our Support center so they can identify where the issue might be- 1-800-821-2797.
I'm sorry I was unable to provide you with more help.
