After initial install (18.3, Cinnamon) on a Lenovo Yoga 720 15-IKB, all is good - everything works great, including the touch pad.
I do the first set of (two) Mint updates, and then Update Manager presents the rest of the available updates. I run those, the touch pad still works, but then after a restart the touch pad doesn't work at all. Mouse and touch screen work fine, but nothing at all from the touch pad. I checked the touch pad settings, and it's switched on. I changed some touch pad settings (speed and sensitivity) to see if that did anything, but still nothing.
I reinstall from live USB and the touch pad works great again...until I run the updates and restart.
UPDATE: after a lot of troubleshooting (and a really valuable learning experience
) I figured out how to boot into a previous kernel (4.10). With the previous kernel, the touch pad works great. 4.13 breaks it. Not sure if there's something that can get around that, so uninstalled 4.13.0-38 and 4.13.0-39.Hoping this can be fixed somehow so future kernel updates don't break it again.
