1.14.2.1
Power Input
When resuming from an AC power failure, the kit returns to the power state it was in before
power was interrupted (on or off). The kit’s response can be set using the Last Power State
feature in the BIOS Setup program’s Boot menu.
1.14.2.2
Instantly Available PC Technology
Instantly Available PC technology enables the kit 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 only
supplying Standby power, and the front panel LED will be amber or secondary color 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 9 on page 31 lists the devices and events that can
wake the computer from the S3 state.
The use of Instantly Available PC technology requires operating system support and drivers for
any installed M.2 add-in card.
1.14.2.3
LAN Wake Capabilities
LAN wake capabilities enable remote wake-up of the kit through a network. The LAN subsystem
monitors network traffic at the Media Independent Interface. Upon detecting a Magic Packet*
frame, the LAN subsystem asserts a wake-up signal that powers up the kit.
1.14.2.4
Wake from USB
USB bus activity wakes the computer from an ACPI S3 state (not after G3).
NOTE
Wake from USB requires the use of a USB peripheral that supports Wake from USB.
1.14.2.5
WAKE# Signal Wake-up Support
When the WAKE# signal on the PCI Express bus is asserted, the kit wakes from an ACPI S3, S4, or
S5 state.
1.14.2.6
Wake from S5
When the RTC Date and Time is set in the BIOS, the kit will automatically wake from an ACPI S5
state.
1.14.2.7
Wake from Consumer IR
CIR activity wakes the kit from an ACPI S3, S4, or S5 state.
