I've written here about my heretic touchpad. Most of the time works fine, but will escape the pen and start acting up a third of the user time. Sluggish cursor (push mightily and it barely moves), erratic almost totally uncontrolable movement. I have and continue to have all fancy movements in options disabled except for basic one finger cursor control. The "Elan Pointing Device " down in the hidden icons which I've left active, shows a single profile of a fingertip moving around on it when things are working fine. When acting up you can see two or even three fingers touching the thing. I use only one.
This is still under an extended warranty and I have resisted sending the unit in as I just don't want to lose the time on it (but if this keeps up I'm liable to step outside and fling this thing all the way to the nearest Lenovo repair center!!)
Can't help but think this is a wonky driver. When acting up you can hit one of several function keys and straighten it right back up for another while.
Well I have a new avenue of thought. Maybe this thing is NOT running on the recommended driver. I have downloaded and installed the one on Lenovo support site (several times)
.......and when a scan of my system is done by the page where this is found it finds I have no need of any drivers.
BUT, when I pull up System Information on the pc and zero in on the lenovo pointing device it shows this:
Driver c:\windows\system32\drivers\i8042prt.sys(10.0.15063.0, 112kb (115,200 bytes), 3/18/2017 4:56PM
Am I to believe this is the driver my Elan clickpad is using? Nowhere near the right number or date. Maybe thats why I am *having* problems.

I have the same system running Win 10 64bit with the latest MS updates and build.
I have no problem at all. First using a wizard for driver updates usually does NOT work. Go to you machine model is support EG. Z70-80 sort and look for newer drivers by the date in inportant groups. Depending on when you last updated your drivers etc!!!
I am using this.

For some reason "System Information" is not showing the true driver. This is what I see using the same path you took.
So I probably have the latest and greatest........
Funny how even tho we have the same pc, yours works all the time with Synoptics, mine has problems with Elan. I guess if I were to send this into the repair center they would replace the Elan hardware????

Well, maybe you can answer a question I have. This involves the maker of the touchpad. Because the driver available on Lenovo's download site seems to support both Elan *and* Synaptics I have assumed that the Z70-80 was sold using touchpads from those two manufacturers. I believe mine uses the ELAN hardware as the driver used is strictly Elan.
I would believe yours uses Synaptics, thus the hardware chooses that part of the driver package to use (and you haven't mentioned the problems I experience).
Or is there only one manyfacturer?
Regarding tech support, I have been remiss on trying them again. After several hours with them when this system was new a couple years ago I gave up on them. (Script readers was a good description!) Will try them again in a few days as SURELY they have heard of this problem by now.
So the question is...........are there two types of touchpad hardware?
I'd like to try the Synaptics side of the driver package if there is only one manufacturer of the touchpad.

As for more than one OEM I could not say.
However, note the follow screen shots. Hardware ID & Drive info show from MS. MS may have updated via Windows Updates!! You could do a manual search via the Update driver button and seach MS Updates.
