I was puzzled by the whole thing when I read up on it a couple of weeks ago.

It is enabled on the BIOS of many systems, even if you don't have a vPro
However, it won't be listening unless the IP had been configured on the
to offer the management services.  Once it is configured, that IP is alive
even when the system is powered off.  Some newer systems have removed the
option from the BIOs to disable IME.  It is like lights out or baseboard
built-in to the main ethernet interface on the mainboard.

Big risk for anyone who has configured it, but just something
to be aware of for the rest of us.
