Instantly Available PC Technology 
 CAUTION 
For Instantly Available PC technology, the 5 V standby line for the power supply must 
be capable of delivering adequate +5 V standby current.  Failure to provide adequate 
standby current when using this feature can damage the power supply and/or effect 
ACPI S3 sleep state functionality. 
 
Instantly Available PC technology enables the board to enter the ACPI S3 (Suspend-to-
RAM) sleep state.  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.   
The Desktop Board supports the PCI Bus Power Management Interface Specification.  
Add-in cards that 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.
