system to S4 (Suspend to Disk) or S5 (Soft-off) state depending on the Power button function setting in the BIOS Setup menu.

2. If the system is in S4 or S5 states, pressing the power button will awaken the system

into S0 states.

3. If the power button is pressed for more than four seconds, a power button over-ride event is generated and the system will be put into S5 (Soft-off) state.
