TLDR: install a 5.x series kernel or fiddle with manual compile and
install of drivers. Lenovo Yogas/IdeaPads are uniquely poorly made and
badly supported by Linux (I have one that needs special attention to
boot normal Ubuntu without throwing ACPI errors so I sympathise).
If you know what you're doing the quickest way to do this and avoid the
catch 22 of not having working network access to download is boot a more
up to date but largely compatible flavour of Linux with newer software
support and a 5.x kernel - I'd use an Ubuntu 19.10 daily iso. Boot that
from USB and chroot into the existing Mint install which will give you
root on Mint with network access via the host Linux. Apt install a
suitable 5.x kernel for Mint and reboot. Upgrade the BIOS/UEFI if
applicable as the next job.
Cheers
