1.15.2.1.3 Intel ME “M” State LED
The board has a red-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 band” Intel manageability
• Moff = Intel ME is in sleep state after Intel ME timeout has occurred
Table 6 shows expected behavior of the “M” state LED.
