Intel Desktop Board DX58SO Technical Product Specification

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 7 on page 31 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.

1.13.2.5

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.

1.13.2.6

PME# Signal Wake-up Support

When the PME# signal on the PCI Conventional bus is asserted, the computer wakes

from an ACPI S1, S3, S4, or S5 state (with Wake on PME enabled in the BIOS).

1.13.2.7

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.
