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 26 on page 50 for the 
location of the power connectors.
