1.11.5.1 Intel Management Engine “M” State LED
The board has a blue-colored Intel ME “M” state LED (see Figure 7). The “M” state is
based on Intel ME status, as follows:
• M0 = Intel ME is in full control in S0
• M3 = Intel ME is in full control in S3-S5 for “out of bound” Intel manageability
• Moff = Intel ME is in sleep state after Intel ME timeout has occurred
Table 7 shows expected behavior of the “M” state LED.
