It's definitely not the 30-minute shutdown.

Since the first day I got the machine, the ME has been stripped down
using the me_cleaner script. I also set the AltMeDisable bit later on.
Although these two modes don't really have a observable difference.

I don't think Intel ME is involved doing the black magic here, but I'll
probably test to run the machine with stock ME firmware when I have time.
