a. Select ME State upon Initial Power-On, and then select On.
Default Setting = Off, Recommended Setting = On
This option sets the behavior of the ME when the system comes out of a G3 state (Mechanical Off
- power outage or power cord removed). If set to ON, the ME will try to automatically power up
the system and obtain memory. Use this option with the ME ON Host Sleep States option.
By default this option is set to OFF because of E-Star power regulatory requirements. HP
recommends setting this option to ON to allow the ME to re-initialize after G3 exit.
If this option is left in the OFF state, then remote management capabilities are lost after G3 exit
and remain lost until the system has entered the S0 (System On) state.

b. Select ME ON in Host Sleep States, and then select Always.

If the settings for steps 10a and 10b are ON and ALWAYS, the ME will automatically wake the
system and obtain system memory after a G3 exit. Steps 10a and 10b work in combination
because 10b dictates if the ME is active during S5, which could be the state of the system after
G3 exit. If the ME is not active in S5, then it will not try to re-initialize itself after G3 exit.
