Intel Desktop Board DH61WW Technical Product Specification 1.16.2.4 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 power LED will behave as configured by the BIOS "S3 State Indicator" option). When signaled by a wake-up device or event, the system quickly returns to its last known wake state. Table 8 on page 33 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. 1.16.2.5 Wake from USB USB bus activity wakes the computer from an ACPI S3 state. NOTE Wake from USB requires the use of a USB peripheral that supports Wake from USB and is supported by the operating system. 1.16.2.6 PME# Signal Wake-up Support When the PME# signal on the Conventional PCI bus is asserted, the computer wakes from an ACPI S3, S4, or S5 state. 1.16.2.7 WAKE# Signal Wake-up Support When the WAKE# signal on a PCI Express add-in card is asserted, the computer wakes from an ACPI S3, S4, or S5 state. 1.16.2.8 Wake from Serial Port Serial port activity wakes the computer from an ACPI S3 state. 1.16.2.9 Wake from PS/2 Devices PS/2 device activity wakes the computer from an ACPI S3, S4, or S5 state. However, when the computer is in an S4 or S5 state, the only PS/2 activity that will wake the computer is the alt-PrtScrn key combination on the keyboard. 36

1.16.2.4
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 power LED will behave as configured by the
BIOS “S3 State Indicator” option).
When signaled by a wake-up device or event, the
system quickly returns to its last known wake state.
Table 8 on page 33 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.
1.16.2.5
Wake from USB
USB bus activity wakes the computer from an ACPI S3 state.
NOTE
Wake from USB requires the use of a USB peripheral that supports Wake from USB
and is supported by the operating system.
1.16.2.6
PME# Signal Wake-up Support
When the PME# signal on the Conventional PCI bus is asserted, the computer wakes
from an ACPI S3, S4, or S5 state.
1.16.2.7
WAKE# Signal Wake-up Support
When the WAKE# signal on a PCI Express add-in card is asserted, the computer wakes
from an ACPI S3, S4, or S5 state.
1.16.2.8
Wake from Serial Port
Serial port activity wakes the computer from an ACPI S3 state.
1.16.2.9
Wake from PS/2 Devices
PS/2 device activity wakes the computer from an ACPI S3, S4, or S5 state. However,
when the computer is in an S4 or S5 state, the only PS/2 activity that will wake the
computer is the alt-PrtScrn key combination on the keyboard.
