The selected power package determines when the Intel ME is turned ON. The
default power package can be modified by using FITC or by FPT.
The end user administrator can choose which power package to use depending on
the systems usage.
The table Above illustrates the details of the power packages.
With Intel
®
ME WoL, after the time-out timer expires, the Intel
®
ME remains in
the M-off state until a command is sent to the ME. After this command has been
sent, the Intel
®
ME will transition to an M0 or M3 state and will respond to the
next command that is sent. A ping to the Intel
®
ME will also cause the Intel
®
ME
to go into an M0 or M3 state.
The Intel ME takes a short time to transition from the M-off state to the M0 or
® ®
commands. When the Intel
®
ME has reached the M0 or M3 state, the system will
respond to Intel
®
ME commands.
