The power button controls the DC power supply output to the system.
NOTE:
If you turn off the system using the power button and the system is
running an ACPI-compliant operating system, the system performs a
graceful shutdown before the power is turned off. If the system is not
running an ACPI-compliant operating system, the power is turned off
immediately after the power button is pressed.
No light — The system is off.
