Product Description

Depending on the LAN implementation, the board supports LAN wake capabilities with ACPI in
the following ways:
• The PCI Express WAKE# signal
• The PCI Conventional bus PME# signal for PCI 2.3 compliant LAN designs
• The onboard LAN subsystem

1.13.2.4 Instantly Available PC Technology

CAUTION

For Instantly Available PC technology, the +5 V standby line for the power supply must be capable
of providing adequate +5 V standby current. Failure to provide adequate standby current when
implementing Instantly Available PC technology can damage the power supply.

Instantly Available PC 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 (the power supply is off,
and the front panel LED is amber if dual colored, or off if single colored.) When signaled by a
wake-up device or event, the system quickly returns to its last known wake state. Table 8 on
page 39 lists the devices and events that can wake the computer from the S3 state.

The board supports the PCI Bus Power Management Interface Specification. Add-in boards that
also support this specification can participate in power management and can be used to wake the
computer.

The use of Instantly Available PC technology requires operating system support and PCI 2.3
compliant add-in cards, PCI Express add-in cards, and drivers.

®

Quick Resume Technology Drivers (Intel

®

QRTD)

The Intel Quick Resume Technology Drivers (Intel QRTD) manage the on and off functions for
Intel

®

Viiv

platforms and have the following features:

• Instantly turns the Intel Viiv platform off by pressing the power button on the PC or remote

control.

• Instantly turns the Intel Viiv platform on by moving the mouse, pressing a key on the keyboard,

or pressing the on/off button on the remote control or computer.

• In the Intel QRTD off state, the:

⎯ Video output stops sending data to the display
⎯ Audio is muted
⎯ Power continues to the vital components on the system (CPU, memory, and fans, for

example).

• The Intel QRTD off state allows tasks that do not require user input to continue in the

background.

• Works with the Microsoft Away mode to offer a complete power management offering for

ACPI and system standby and hibernate.

• Target resume time is zero to five seconds (about equal to the time it takes for the display to

warm up).
