Computer Setup-Power NOTE: Support for specific Computer Setup options may vary depending on the hardware configuration. Table 3-5 Computer Setup-Power Option OS Power Management Hardware Power Management Thermal Description ● Runtime Power Management- Enable/Disable. Allows certain operating systems to reduce processor voltage and frequency when the current software load does not require the full 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. Default is disabled. ◦ S0 (On) = Solid green LED. ◦ S3 (Stand By)= 3 blinks at 1Hz (50% duty cycle) followed by a pause of 2 seconds (green LED) - repeated cycles of 3 blinks and a pause. ◦ S4 (Hibernation)= 4 blinks at 1Hz (50% duty cycle) followed by a pause of 2 seconds (green LED) - repeated cycles of 4 blinks and a pause. ◦ S5 (Soft Off) = LED is off. NOTE: If this feature is disabled, S4 and S5 both have the LED off. S1 (no longer supported) and S3 use 1 blink per second. SATA Power Management - Enables or disables SATA bus and/or device power management. Default is enabled. S5 Maximum Power Savings-Turns off power to all nonessential hardware when system is off to meet EUP Lot 6 requirement of less than 1 Watt power usage. Default is disabled. Fan idle mode-This bar graph controls the minimum permitted fan speed. NOTE: This setting only changes the minimum fan speed. The fans are still automatically controlled.
