make the Intel ME transition to an M0 or M3 state. Intel ME
takes a short time to transition from the M-off state to the M0

indicates the amount of time that the Intel ME is allowed to
remain idle in the M3 state before transitioning to the M-off
state. The idle timeout value should be entered in minutes.

the M-off state.
