Instantly Available PC Technology

CAUTIONS
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.
Power supplies used with this desktop board must be able to provide enough standby
current to support the standard Instantly Available (ACPI S3 sleep state) configuration.
If the standby current necessary to support multiple wake events from the PCI and/or
USB buses exceeds power supply capacity, the desktop board may lose register
settings stored in memory.
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. If
the computer has a dual-colored power LED on the front panel, the sleep state is
indicated by the LED turning amber. When signaled by a wake-up device or event, the
computer quickly returns to its last known awake 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.
