	capabilities of the processor. Default is enabled.
	● Idle Power Savings—Extended/Normal. Allows certain operating systems to decrease the
	processors power consumption when the processor is idle. Default is extended.
	● Unique Sleep State Blink Rates—Enable/Disable. This feature is designed to provide a visual
	indication of what sleep state the system is in. Each sleep state has a unique blink pattern.

	◦	S3 (Stand By)= 3 blinks at 1Hz (50% duty cycle) followed by a pause of 2 seconds
		(white LED) — repeated cycles of 3 blinks and a pause.
