I don't know if this will help, but I read a post somewhere (don't
remember where) of someone who had troubles with the Ideapad 110S
-- sound, touchpad, suspend, etc. -- after replacing Windows 10 with
Stretch.  Installing a newer kernel from Stretch-Backports rectified
those issues along with non-free firmware in the Stretch Repos and/or
proprietary drivers.

I'm interested in any solutions you discover.  I'm looking at the 110S
as a light, compact "travel" notebook.
