Hi my name is ***** ***** I will be the expert working with you today to help and resolve the problem you have posted.I am sorry to hear that you are having such trouble. I will try my best to help you out and resolve the problem as quick as possible.
you will have to let the Lenovo Yoga be on the laptop mode and then open device manager and remove touchpad and mouse driver and restart the computer after that.
Download and install the drivers back and update it that will take care of the problem.
not a problem remote access is only good to go when we are communicating from the problem computer.
I gave you steps to follow did you follow the driver removal steps?
i know its updated with latest update however if the file is corrupted it will not ask you to remove it and reinstall it back.
Try to remove the drivers and restart the computer download and install the latest driver back and that should take care of the sync while you doc or undock the yoga.
