I've tried adding these kernel parameters in GRUB before boot placing them just between the "splash" and "---":

    i8042.nopnp=1 pci=nocrs

(according to here https://www.reddit.com/r/linuxquestions/comments/f9h0q4/touchpad_issue_lenovo_s14515iil/fmg277m/ )

And voila!
- Touchpad is working
- Touchscreen is working
- pen/Stylus is NOT working properly - it behaves only just like if using a finger - no additional functionality except for basic "clicking"

BUT! according to kernel documentation ( https://www.kernel.org/doc/html/v4.10/admin-guide/kernel-parameters.html ) - this is a BUG and shall be reported:

                nocrs [X86] Ignore PCI host bridge windows from ACPI.
                                If you need to use this, please report a bug.

So... what are next steps, please?

Thanks
