Hardware Support; Wake-Up Devices And Events - Intel BLKDQ965GFEKR Technical Product Specification

1.12.1.2 Two-Watt Standby
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.
Newer energy-efficient power supplies using less than 0.5 W (in Standby mode) may
also be needed to achieve this goal.
1.12.1.3

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...
LAN
PME# signal
Power switch
PS/2 devices
RTC alarm
Serial port
USB
WAKE# signal
Note: For LAN and PME# signal, S5 is disabled by default in the BIOS Setup program. Setting this option to
Power On will enable a wake-up event from LAN in the S5 state.
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.

Hardware Support

CAUTION
Ensure that the power supply provides adequate +5 V standby current if LAN wake
capabilities and Instantly Available PC technology features are used. 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.
The board provides several power management hardware features, including:
• Power connector
• Fan headers
