The operating system puts devices in and out of low-power states based on user preferences and knowledge of how devices are being used by applications. Devices that are not being used can be turned off. The operating system uses information from applications and user settings to put the system as a whole into a low-power state. 37 Intel Desktop Board D955XBK Technical Product Specification Table 7 lists the power states supported by the board along with the associated system power targets. See the ACPI specification for a complete description of the various system and power states. Table 7.

For LAN and PME# signal, S5 is disabled by default in the BIOS Setup program. Setting this option to Power On will enable a wake-up event from LAN in the S5 state. NOTE The use of these wake-up events from an ACPI state requires an operating system that provides full ACPI support. In addition, software, drivers, and peripherals must fully support ACPI wake events. 1. 14. 2 Hardware Support CAUTION Ensure that the power supply provides adequate +5 V standby current if LAN wake capabilities and Instantly Available PC technology features are used. Failure to do so can damage the power supply. The total amount of standby current required depends on the wake devices supported and manufacturing options. The board provides several power management hardware features, including: · · · · · · · · · Power connector Fan connectors LAN wake capabilities Instantly Available PC technology Resume on Ring Wake from USB Wake from PS/2 keyboard PME# signal wake-up support WAKE# signal wake-up support LAN wake capabilities and Instantly Available PC technology require power from the +5 V standby line.
