Note:
NOTE
The use of these wake-up events from an ACPI state requires an operating system that provides full
ACPI support. In addition, software, drivers, and peripherals must fully support ACPI wake
events.
CAUTION
Ensure that the power supply provides adequate +5 V standby current if LAN wake capabilities
and Instantly Available PC technology features are used. Failure to do so can damage the power
supply. The total amount of standby current required depends on the wake devices supported and
manufacturing options. Refer to Section 2.11.3 on page 81 for additional information.
