Status
Note: Blink rate is ~1 Hz at 50% duty cycle.
It is also off when the system is powered off (S5) or in a sleep state (S1).
The power LED sleep indication is maintained on standby by the chipset. If the system is
powered down without going through the BIOS, the LED state in effect at the time of
power off is restored when the system is powered on until the BIOS clear it.
If the system is not powered down normally, it is possible the Power LED will blink at the
same time the system status LED is off due to a failure or configuration change that
prevents the BIOS from running.
