Under Windows 10-64 two devices (both named "pci communication controller") lack proper drivers as indicated by exclamation marks.
Problem occurs after Windows Update automatically installs all relevant drivers for this model.
Problem still persits after installing ALL drivers for this model that are provided by Lenovo's website under either:
Lenovo Service Bridge (LSB) also DOES NOT provide the missing drivers.
I understand the problem is connected with something called "Intel AMT (Active Management Technology) Management Engine Interface", as described here (in Greman though):
NONE of the Intel Management Engine Interface drivers released in 2017 provided by Lenovo's website for any other model notebook solves the problem! In fact all but one fail to even install. Just one package named "fl5m01af" installs drivers for something called "Intel (MEIx64) System (11/16/2016 188.8.131.522)".
How do I solve this?

If UEFI is activated instead of legacy boot in BIOS, all existing partitions are deleted and recreated as GPT, W10-64 is clean-installed and given the time to get all driver updates (no need for Lenovo driver downloads!), the unknown devices will be gone! Thanks Lenovo, for being of absolutely no help in this matter!

I am having similar problem with a 720S... the TB firmware is not present on the PCI bus.
Is the solution to disable EFI and boot from bios?
