Can I disable the touchpad in a Lenovo laptop?

In June a friend bought a Lenovo Z50-70 laptop running Win 8.1. He particularly dislikes touchpads so uses a mouse. In 8.1 I was able to disable the touchpad for him, via Device Manager. He's now updated to Win 10 and the touchpad has come back to life. I've been trying to disable it again, so far without success.

In "Settings", the only option under touchpad is to alter the delay on using "click". No help there so I went to Control Panel.

In "Device Manager > Mice and other pointing devices" there are only two options, "HID-compliant mouse" (which has a disable option) and "Lenovo Pointing Device", which I assume refers to the touch pad (is this assumption right?) and which can be uninstalled but has no "disable" option.

In "Device Manager > Human Interface Devices" amongst other things there are two entries both named "HID-compliant vendor-defined device". Both can potentially be disabled, but without further knowledge I'm disinclined to disable them in case I inadvertently disable the mouse in the process.

Any advice will be appreciated

Hi!

"Lenovo Pointing Device", which I assume refers to the touch pad (is this assumption right?)

Yes! This is right.

Try this Driver:

Thanks Cluster Head for confirming my assumption. I'd already checked (from Device Manager) that the Driver for that device is up-to-date.
