The Energy Star program, a government-backed initiative, promotes energy efficiency by identifying
ways to reduce energy consumption. Select HP workstations participate in the Energy Star program.
For those workstations that support Energy Star and have it enabled, the power management features
are set as follows:
The monitor goes into power savings mode after 20 minutes of inactivity.
The system goes into standby mode after 20 minutes of inactivity
after the restore.
To verify the factory default power settings for your product, select Start>Control Panel and double-
click Power Options.
Energy Star compliance
HP products purchased with the Energy Star configuration are compliant with U.S. Environmental
Protection Agency (EPA) Computers Program. The EPA Energy Star configuration does not imply
endorsement by the EPA. As an Energy Star partner, HP offers products with the Energy Star
configuration to meet the Energy Star guidelines for energy efficiency.
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.
might cause video distortion when the Energy Save timeout occurs.
Energy Star is not supported on Linux-based workstations.
If you have to restore the operating system, reset the Energy Star settings (if applicable)
