8 Computer Setup (F10) Utility
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.
●
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 PS2 mouse activity.
●
USB Wake on Device Insertion (some models)—Allows system to wake from Standby on USB
device insertion.
●
Unique Sleep Blink Rates—This feature is designed to give the user a visual indication of the
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), i.e.,
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), i.e.,
repeated cycles of 4 blinks and a pause.
◦
S5 = LED is off.
If this feature is disabled, S4 and S5 both have the LED off. S1 (no longer supported) and S3
use 1 blink per second.
● S5 Maximum Power Savings (some models)—Enable/Disable. Enabling this feature reduces
the power of this system as much as possible in the S5 state. Power is removed from the wake
up circuitry, the expansion slots, and any management features while in S5.
●
SATA power management enables or disables SATA bus and/or device power management.
●
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.
