Intel Desktop Board DH67BL Product Guide

Chassis Intrusion

The board supports a chassis security feature that detects if the chassis cover has
been removed. The security feature uses a mechanical switch on the chassis that can
be connected to the chassis intrusion header on the Desktop Board. See Figure 1 for
the location of the chassis intrusion header.

Power Management

Power management is implemented at several levels, including software support
through the Advanced Configuration and Power Interface (ACPI) and the following

hardware support:

•

Power connectors

• Fan headers
• LAN wake capabilities
• Instantly Available PC technology (Suspend to RAM)
• +5 V standby power indicator LED
• Wake from USB
• PCI Express WAKE# signal support
• Wake from CIR

Software Support

ACPI

ACPI gives the operating system direct control over the power management and Plug
and Play functions of a computer. The use of ACPI with the Desktop Board requires an
operating system that provides full ACPI support.
Hardware Support
Power Connectors
ATX12V-compliant power supplies can turn off the computer power through system
control. When an ACPI-enabled computer receives the correct command, the power
supply removes all non-standby voltages.
When resuming from an AC power failure, the computer returns to the power state it
was in before power was interrupted (either on or off). The computer's response can
be set by using the Last Power State feature in the BIOS Setup program's Boot menu.
The Desktop Board has two power connectors. See Figure 23 on page 51 for the
location of the power connectors.
