Lenovo Yoga i7 touchpad, touchscreen and function keys (F1 - F10) not working

[gorne]

Hello,
I have installed Linux Lite 5.6 in a laptop Lenovo Yoga i7.
I am experiencing several issues:
    1- touchpad does not work
    2- all function keys do not work. For example, I can not close a window with Alt+F4, I can not rise/down the sound volume with Fn+F2/F3, etc
    3- touchscreen does not work (this is the less I am concerned about)

The laptop is new and all the hardware work, I know because all hardware work properly in Windows.
Using an external keyboard and mouse works properly.

Any help??
Thanks in advance

I am not sure how it helps, but I found that I should check this information out:
