Product Description 1.12.2.4 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-toRAM) 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 9 on page 32 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 2.2 compliant add-in cards, PCI Express add-in cards, and drivers. 1.12.2.5 Wake from USB USB bus activity wakes the computer from ACPI S1 or S3 states. NOTE Wake from USB requires the use of a USB peripheral that supports Wake from USB. 1.12.2.6 PME# Signal Wake-up Support When the PME# signal on the Conventional PCI bus is asserted, the computer wakes from an ACPI S1, S3, S4, or S5 state (with Wake on PME enabled in the BIOS). 1.12.2.7 WAKE# Signal Wake-up Support When the WAKE# signal on the PCI Express bus is asserted, the computer wakes from an ACPI S1, S3, S4, or S5 state. 1.12.2.8 Wake from Consumer IR CIR activity wakes the computer from an ACPI S3, S4, or S5 state. 35

1.12.2.4
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 9 on page 32 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 2.2 compliant add-in cards, PCI Express add-in cards, and drivers.
1.12.2.5
Wake from USB
USB bus activity wakes the computer from ACPI S1 or S3 states.
±
NOTE
Wake from USB requires the use of a USB peripheral that supports Wake from USB.
1.12.2.6
PME# Signal Wake-up Support
When the PME# signal on the Conventional PCI bus is asserted, the computer wakes
from an ACPI S1, S3, S4, or S5 state (with Wake on PME enabled in the BIOS).
1.12.2.7
WAKE# Signal Wake-up Support
When the WAKE# signal on the PCI Express bus is asserted, the computer wakes from
an ACPI S1, S3, S4, or S5 state.
1.12.2.8
Wake from Consumer IR
CIR activity wakes the computer from an ACPI S3, S4, or S5 state.
