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.
S5 Wake on LAN (enable/disable). Default is disable.
●
To disable Wake on LAN during the off state (S5), use the arrow (left and right) keys to
select the Advanced > Device Options menu and set the S5 Wake on LAN feature to
Disable. This obtains the lowest power consumption available on the computer during S5. It
does not affect the ability of the computer to Wake on LAN from suspend or hibernation, but
will prevent it from waking from S5 via the network. It does not affect operation of the
network connection while the computer is on.
●
If a network connection is not required, completely disable the network controller (NIC) by
using the arrow (left and right) keys to select the Security > Device Security menu. Set the
Network Controller option to Device Hidden. This prevents the network controller from being
used by the operating system and reduces the power used by the computer in S5.
