I did a search to see if this was already posted but didn't find it. So, here's my story.
I have a P40 Yoga that's about a year old. A couple of weeks ago, I received a pop-up from Lenovo Vantage saying there was a system update. Like a good user, I said OK. I didn't notice it right away (because I use an external mouse) but the trackpad, left/right click buttons and the "trackpoint" center button all stopped working. I did a lot of searching to see if there was a resolution but couldn't find one.
Eventually, I went into Control Panel | Device Manager | Mice and other pointing devices | ELAN pointing device | Driver and saw that there was a recent update. Fortunatly, there was a "Roll Back Driver" option which I figured couldn't hurt anything. After a reboot, the driver is back to one dated 2/13/2017 version 126.96.36.199. All mouse accoutrements are once again working.
What prompted me to post today is that the Lenovo Vantage pop-up appeared again telling me there's an update and it wants to put the bad driver back. Irconically, the pop-up says:
"Lenovo recommends that you install these updates to optimize your computer"
Yah, right! Now I'm sceptical about ever doing another update.
