1.10.1.1
1.10.1.2 Two-Watt Standby
Under ACPI, the operating system directs all system and device power state
transitions. The operating system puts devices in and out of low-power states based
on user preferences and knowledge of how devices are being used by applications.
Devices that are not being used can be turned off. The operating system uses
information from applications and user settings to put the system as a whole into a
low-power state.
Table 8 lists the power states supported by the board along with the associated
system power targets. See the ACPI specification for a complete description of the
various system and power states.

In 2001, the U.S. government issued an executive order requiring a reduction in
power for appliances and personal computers. This board meets that requirement by
operating at 1.5 W (or less) in S5 (Standby) mode. Two-Watt operation applies only
to the S5 state when the computer is turned off, but still connected to AC power.
Two-Watt operation does not apply to the S3 (Suspend to RAM) or S4 (Suspend to
disk) states.
