Wake Up Devices and Events

These devices/events can wake-up the computer...
Power switch
RTC alarm
LAN
PME#
USB
1.12.1.3 Plug and Play
In addition to power management, ACPI provides controls and information so that the operating
system can facilitate Plug and Play device enumeration and configuration. ACPI is used only to
enumerate and configure devices that do not have other hardware standards for enumeration and
configuration. PCI devices on a desktop board, for example, are not enumerated by ACPI.

1.12.2 Hardware Support

CAUTION
If Wake on LAN and Instantly Available technology features are used, the power supply must be
capable of providing adequate +5 V standby current. Failure to provide adequate standby current
can damage the power supply. The total amount of standby current required depends on the wake
devices supported and manufacturing options. Refer to Section 2.11.2 on page 63 for additional
information.
The board provides several hardware features that support power management, including:
•
Power connector
•
Fan connectors
•
Wake on LAN technology
•
Instantly Available technology
•
Wake on Ring
•
Resume on Ring
•
Wake from USB
•
PME# wakeup support
Wake on LAN technology and Instantly Available technology require power from the +5 V
standby line. The sections discussing these features describe the incremental standby power
requirements for each.
Wake on Ring and Resume on Ring enable telephony devices to access the computer when it is in
a power-managed state. The method used depends on the type of telephony device (external or
internal) and the power management mode being used (ACPI).
