I've spent maybe total of 8+ hours finding the solution to this.. unfortunately CommanderHusky's solution didn't work for me I got an error message "unable to connect to the synaptics pointing device driver" too. 


I found a solution that worked for me accidentally, haha. Turns out there are legacy drivers for Elan I found on a dell touchpad installation tutorial.

I got the "Elan Touchpad Windows 10 64 Bit" driver and opened the ETDAniConf to configure the trackpad settings, at first it didn't work so I found this on reddit:


Open regedit.exe using run

2. Go to HKEY_CURRENT_USER -> SOFTWARE -> Elantech -> Smartpad

3. Change ScrollControl_Mode from 0 to 1

4. Open the elan software and click apply just to make sure the settings get applied


This enabled me to make the changes I do in ETDAniConf apply everwhere (even in brave/opera web browser) 

Geesus.. this just caused so much inconvenience, literally spent hours deep diving in forums if only Lenovo just updated the trackpad drivers when they've heard complaints in their forums..
