NOTE: Support for specific Computer Setup options may vary depending on the hardware
configuration.
Table 2-5 Computer Setup—Power
Option Description
OS Power
Management ● 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.
● Idle Power Savings—Extended/Normal. Allows certain operating systems to decrease the
processors power consumption when the processor is idle.
● ACPI S3 Hard Disk Reset—Enabling this causes the BIOS to ensure hard disks are ready to
accept commands after resuming from S3 before returning control to the operating system.
● ACPI S3 PS2 Mouse Wakeup—Enables or disables waking from S3 due to any PS2 mouse
activity or a button click only.
● USB Wake on Device Insertion (some models)—Allows system to wake from Standby on
USB device insertion.
● 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.
◦ S0 = Solid green LED.
◦ S3 = 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 = 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 = 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.
Hardware Power
Management SATA Power Management enables or disables SATA bus and/or device power management.
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.
Thermal 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.
