Option Description
Enabling this feature reduces the power of the 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.
Default is disabled.
SATA Power Management (enable/disable)
Enables or disables SATA bus and/or device power management. Default is enabled.
PCI Express Power Management (enable/disable)
Enabling this option permits the PCI Express links to use Active Power State Management (ASPM) to enter
lower power states while not in use. Default is enabled.
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.
NOTE: A normal shutdown goes to the S4 state.
S0 (On) = Solid white LED.
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.
S4 (Hibernation)= 4 blinks at 1Hz (50% duty cycle) followed by a pause of 2 seconds (white LED) —
repeated cycles of 4 blinks and a pause.
S5 (Soft Off) = LED is off.
Recovering the Configuration Settings
This method of recovery requires that you first perform the Save to Removable Media command with the
Computer Setup (F10) Utility before Restore is needed. (See
Computer Setup–Main on page 79 in the

NOTE: It is recommended that you save any modified computer configuration settings to a USB flash media
device and save the device for possible future use.
To restore the configuration, insert the USB flash media device with the saved configuration and perform the
Restore from Removable Media command with the Computer Setup (F10) Utility. (See
