That probably explains why something like that shows up on the output of lspci when almost everything else (including lenovo's spec sheet[1]) points to the machine not having amt.

For reference this is a lenovo e560 and this is what I get from lspci regarding the communications controller:

00:16.0 Communication controller [0780]: Intel Corporation Sunrise Point-LP CSME HECI #1 [8086:9d3a] (rev 21)

I guess this is one of those times when one is happy not to have certain functionalities.
