✏
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.
✏
NOTE
Wake up from PS/2 mouse is peripheral, operating system, and driver dependent.
1.13.1.1.3 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 D815EGEW board devices that do not have other hardware standards for
enumeration and configuration. PCI devices on the D815EGEW board, for example, are not
enumerated by ACPI.

1.13.2 Hardware Support

CAUTION
If the Wake on LAN and Instantly Available technology features are used, ensure that the power
supply provides adequate +5 V standby current. 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 68 for additional information.
The boards provides several hardware features that support power management, including:
•
Power connector
•
Fan connectors
•
Wake on LAN technology connector (optional)
•
Instantly Available technology
•
Resume on Ring
•
Wake from USB
•
Wake from PS/2 keyboard
•
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.
Resume on Ring enables 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).
