Instantly Available PC Technology
Instantly Available PC technology enables the Compute Card 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 off). When signaled by a wake-up device or event, the system
quickly returns to its last known wake state. Table 5 on page 18 lists the devices and events that
can wake the Compute Card from the S3 state when the Compute Card is plugged into a
compatible device.
The use of Instantly Available PC technology requires operating system support.
1.12.2.2
Wired LAN Wake Capabilities
Wired LAN wake capabilities enable remote wake-up of the Compute Card through a network.
The Wired LAN subsystem monitors network traffic at the Media Independent Interface. Upon
detecting a Magic Packet* frame, the Wired LAN subsystem asserts a wake-up signal that powers
up the Compute Card. Only available when plugged into a compatible device that has support for
Wired LAN.
1.12.2.3
Wireless LAN Wake Capabilities
Wireless LAN wake capabilities enable remote wake-up of the Compute Card through a network.
The Wireless LAN subsystem monitors network traffic at the Media Independent Interface. Upon
detecting a Magic Packet* frame, the Wireless LAN subsystem asserts a wake-up signal that
powers up the Compute Card.
1.12.2.4
Wake from USB
USB activity wakes the Compute Card from an ACPI S3 and S4 states.
NOTE
Wake from USB requires the use of a USB peripheral that is plugged into a compatible device that
supports Wake from USB.
1.12.2.5
Wake from S5
When the RTC Date and Time is set in the BIOS, the Compute Card will automatically wake from
an ACPI S5 state.
