I've been using a Lenovo s145-iil and I just have installed Zorin OS 15.3 but my touchpad doesn't work, I was using Windows on this machine and everything was working fine, someone could help me please with this issue? Thanks.
I am not sure if it will be solved by upgrading to Zorin 16, but there seems to be a fix for Ubuntu 18.04 (which Zorin 15.3 is based on).
See what happens when I get in a hurry? I misread the O.P.
