1.13.2.3  LAN Wake Capabilities 
LAN wake capabilities enable remote wake-up of the computer 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 computer. 
1.13.2.4  Instantly Available PC Technology 
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 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 12 on page 41 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 PCI Express add-in card. 
1.13.2.5  Wake from USB 
USB bus activity wakes the computer from an ACPI S3 state. 
 
NOTE 
Wake from USB requires the use of a USB peripheral that supports Wake from USB. 
 
 
1.13.2.6  WAKE# Signal Wake-up Support 
When the WAKE# signal on the PCI Express bus is asserted, the computer wakes from 
an ACPI S3, S4, or S5 state. 
1.13.2.7  Wake from Consumer IR 
CIR activity wakes the computer from an ACPI S3, S4, or S5 state. 
1.13.2.8  Wake from S5 
When the RTC Date and Time is set in the BIOS, the computer will automatically wake 
from an ACPI S5 state.
