I had touchpad problems with my Lenovo IdeaPad S145-IIL. For that there is a solution, that model needs a community kernel module and some GRUB config tweaking to fix it:

https://askubuntu.com/questions/1220264/lenovo-ideapad-s145-touchpad-not-working

 

You may try this, or look for other forks of this 'elan_i2c_dkms' kernel module made for some model which is in closer relation to yours, and try to find what key=value arguments you need to put in GRUB_CMDLINE_LINUX_DEFAULT for your model.

 

I hope you will manage to solve this issue.

 

ps. I definitely blame Lenovo for this, not the kernel: my story is that while S145 is mainly sold with preinstalled Windows (with preinstalled drivers so working well) - when I bought my one without OS I first installed a Win 10 on it. And guess what, the touchpad didn't work in the Win10 installer either. I pushed through half of the Win10 installer with smashing tab + arrows. (Then I realized I should plug in an usb mouse...  May say silly of me but when you preform a first time install one should prefer to do it without peripherals connected... Of course when its done and Win 10 first boots up first it installs the driver and starts working.).

That is very odd. Lenovo tends to actually like Linux a ton! specially in the Think/Ideapad series. Although I guess if it happening, it's def not Linux's mistake
