Ok.

Well, to know what it should be doing, you really need to run it under
Windows *with* the Lenovo drivers ("thinkvantage suite") loaded.
But, since it was cooking itself with the lid closed, and now it is not
cooking itself anymore, I'd say it is at least *safer* to keep it set to
"balanced" for now.

Hmm, check if you have "thermald" running. If you do, try without it
(but keep a close look at temperatures the entire time!). If you don't,
try installing it.
thermald is prone to do very idiotic things on Xeon processors, but for
laptops with mobile processors, it is often a good way to work around
misbehavior.

LID events are actually handled by the acpi "lid" driver, which is sane
on 4.9, but currently insanely broken on 4.11 (and maybe 4.10) -- the
breakage is in the process of being reverted.
Lenovo woudln't add a *new* "LID changed" helper event (like the one you
reported) if its drivers did not have to handle it *differently* from
what is already in there. I think we actually need to know what happens
in Windows to correctly handle this one.
