HP Xw8400 - Workstation - 4 GB RAM Technical Reference Manual page 22

EPA created the Energy Star Computers Program to promote energy efficiency and reduce air pollution
through more energy-efficient equipment in homes, offices, and factories. HP products achieve this
result by reducing the power consumption when not being used.
Energy Star on HP workstations uses Advanced Configuration and Power Interface (ACPI) power
management. The system can wake as a result of a user action (keyboard or mouse) or from the network
or a modem.
The Power Management feature, when used in conjunction with an external Energy Star-compliant
monitor, will support the power-down features of the monitor. The Power Management feature allows
an external monitor to go into low-power mode when the Energy Save timeout occurs.
NOTE: Using the Energy Star Save Monitor feature with non-Energy Star-compliant monitors might
cause video distortion when the Energy Save timeout occurs.
