Wake-up Devices and Events

Table 10 lists the devices or specific events that can wake the computer from specific
states.
Table 10. Wake-up Devices and Events
These devices/events can wake up the computer...
Power switch
RTC alarm
LAN
USB
WAKE#
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.
