Intel Desktop Board DH55HC Product Guide

Wake from USB

NOTE

Wake from USB requires the use of a USB peripheral that supports Wake from USB and an operating system that supports Wake from USB.

USB bus activity wakes the computer from an ACPI S1 or S3 state.

PCI PME# Signal Wake-up Support

When the PME# signal on the PCI bus is asserted, the computer wakes from an ACPI S1, S3, S4, or S5 state.

PCI Express WAKE# Signal Wake-up Support

When the WAKE# signal on a PCI Express bus add-in card is asserted, the computer wakes from an ACPI S1, S3, S4, or S5 state.

Wake from PS/2 Devices

PS/2 device activity can wake the computer from an ACPI S1, S3, S4, or S5 state. When the computer is in the S4 state, any key can be used to wake the computer provided a supported operating system is installed. When the computer is in the S5 state, the only PS/2 activity that will wake the computer is either the Alt-Print Screen key combination or the “Power” key that is available on some keyboards. The BIOS can be used to select between either of the key combinations.

Wake from Serial Port

Serial port activity wakes the computer from an ACPI S1 or S3 state.
