Notes:
1. S4 implies operating system support only.
2. Wake on LAN is only supported from sleep (S3) or hibernate (S4) in Windows 8.
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.
