Wake from USB

NOTE

Wake from USB requires the use of a USB peripheral that supports Wake from USB
and an operating system that supports Wake from USB.

USB bus activity wakes the computer from an ACPI S3 state.

PME# Signal Wake-up Support

When the PME# signal on the PCI bus is asserted, the computer wakes from an
ACPI S1, S3, S4, or S5 state.

WAKE# Signal Wake-up Support

When the WAKE# signal on the PCI Express bus is asserted, the computer wakes from
an ACPI S1, S3, S4, or S5 state.

ENERGY STAR* Capable

In 2007, the US Department of Energy and the US Environmental Protection Agency
revised the ENERGY STAR requirements. Intel worked directly with these two
governmental agencies to define the new requirements. Currently Intel Desktop
Boards are capable of meeting the new ENERGY STAR requirements depending upon
system configuration.

ENERGY STAR requirements:

Onboard Power Button

CAUTION

Electrostatic discharge (ESD) can damage components. Perform the procedure
described in this section only at an ESD workstation using an antistatic wrist strap and
a conductive foam pad. If such a station is not available, you can provide some ESD
protection by wearing an antistatic wrist strap and attaching it to a metal part of the
computer chassis.

A power button on the Desktop Board (see Figure 5) can be used to turn the computer
on or off. This button is intended for use at integration facilities to remove standby
power before making changes to the system configuration, or for testing purposes.
The power button on the front panel is recommended for all other instances of turning
the computer on or off. To turn off the computer using the onboard power button,
keep the button pressed down for three seconds.
