2. ON to Standby state: The system will go into the Standby state when Ibex Peak-M receives the POS
command.
3. ON to Suspend state: The system will go into Suspend state when Ibex Peak-M receives the S2R
command.
4. ON to Hibernate state: The system will go into Hibernate state when Ibex Peak-M receives the S2D
command.
5. ON to Soft Off state: The system will go into Soft Off state when Ibex Peak-M receives the Soft off
command.
6. Standby to ON state: The system will go into ON state when the system receives any wake up events, for
example, keyboard, mouse.
7. Suspend to ON state: The system will go into ON state when the power button is pressed.
