Table 6-3 Computer Setup Advanced (for advanced users) (continued)
Option Heading
Power Management
Options
Runtime Power Management
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.
Extended Idle Power States
Allows certain operating systems to decrease the processors power consumption when the
processor is idle. Default is enabled.
S5 Maximum Power Savings
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
Enables or disables SATA bus, device power management, or both. Default is enabled.
PCI Express Power Management
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.
Power On from Keyboard Ports
When enabled, this feature allows a key press to turn on the system when it is off (S5 state). If using
a USB keyboard, you must plug it into one of the rear ports labeled with the keyboard icon. Default is
disabled.
Unique Sleep State Blink Rates
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 for Windows 8 or later.
S0 (On) = solid white light.
S3 (Stand By) = 3 blinks at 1 Hz (50% duty cycle) followed by a pause of 2 seconds (white light),
repeated cycles of 3 blinks and a pause.
S4 (Hibernation) = 4 blinks at 1 Hz (50% duty cycle) followed by a pause of 2 seconds (white light),
repeated cycles of 4 blinks and a pause.
S5 (Soft Off) = Light is off.
Power Supply Options
Your computer can use one or two power supply units in one of three configurations:
● Single—One power supply (with one power cord) is installed in the computer.
● Redundant—Two power supplies (with two power cords) are installed in the computer, but only
one power supply is in use at a time. If the power supply currently in use fails, the computer
automatically switches to the second power supply.
● Aggregate—Two power supplies (with two power cords) are installed in the computer, and both
are in use at the same time.
NOTE: When selecting the Aggregate power supply configuration, be sure that the power
supply is connected to a separate circuit breaker.
