Intel BLKD865GBF Specification page 55

Product Description
1.13.2.4 Instantly Available PC Technology
CAUTION
For Instantly Available PC technology, the +5 V standby line for the power supply must be
capable of providing adequate +5 V standby current. Failure to provide adequate standby current
when implementing Instantly Available PC technology can damage the power supply.
Instantly Available PC technology enables the Desktop Boards D865GBF and D865GLC 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 LED is amber if dual colored, or off if single
colored.) When signaled by a wake-up device or event, the system quickly returns to its last
known wake state. Table 17 on page 52 lists the devices and events that can wake the computer
from the S3 state.
The Desktop Boards D865GBF and D865GLC support the PCI Bus Power Management Interface
Specification. For information on the version of this specification, see Section 1.5.
Add-in boards that also 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 and drivers.
