Being somewhat new to the Purism world, I’d just like to know if I’m missing something. According to this Purism link, out of band system access via Intel AMT/ME is only possible if the Intel CPU supports the vPro feature set. But many of the latest Intel processors (for example the i7-7500 in the latest Lenovo Ideapad 320) do not have the Intel VPro technology, making (per the Purism link above) out of band remote access impossible.
I get that you can’t be too suspicious about something like Intel ME and that it’s therefore a great idea to gut it as much as possible, but isn’t simply avoiding putting Intel Vpro processors in the Librem enough? If I buy a laptop with a non-Vpro Intel processor, could an attacker still remotely turn on & mess with the laptop? What am I missing here?
