Power Management Features

Power management is implemented at several levels, including:


Software support:

Advanced Power Management (APM)

Advanced Configuration and Power Interface (ACPI)


Hardware support:


Wake on LAN technology



Instantly Available technology


Wake on Ring

Resume on Ring
If the board is used with an ACPI-aware operating system, the BIOS can provide ACPI support.
Otherwise, it defaults to APM support.
Wake on LAN Technology
The Wake on LAN technology connector can be used with PCI bus network adapters that have a
remote wake-up connector. Network adapters that are PCI 2.2 compliant assert the wake-up signal
using the PCI bus signal PME# (pin A19 on the PCI bus connectors). See Figure 6 on page 61 for
the location of the Wake on LAN technology connector.
CAUTION
For Wake on LAN technology, the 5-V standby line for the power supply must be capable of


delivering +5 V
feature can damage the power supply.
Instantly Available Technology
Instantly Available technology enables the board to enter the ACPI S3 (Suspend-to-RAM) sleep
state. While in the S3 sleep state, the computer will appear to be off. When signaled by a wake-up
device or event, the system quickly returns to its last known awake state.
The motherboard standby power indicator is lit when the memory modules and PCI bus connectors
have power, even when the computer appears to be off.
If the system has a dual-colored power LED on the front panel, the sleep state is indicated by the
LED turning amber. For more information about front panel LED states, see the Desktop Board
VC820 Technical Product Specification.
