ENERGY STAR

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.
NOTE: ENERGY STAR is not supported on Linux-based workstations.
For those workstations purchased with the Energy Star option and have it enabled, the power management features will
be set as follows:
• Monitor—goes into sleep mode after 20 minutes of inactivity.
• System—goes into Standby mode after 20 minutes of inactivity.
• Hard Drive—goes into power savings mode after the system goes into Standby mode.
NOTE: If you have to restore the operating system, reset the ENERGY STAR settings (if applicable) after the restore.
To verify the factory default power settings for your product, select Start > Control Panel and double-click Power
Options.

1.6.1 ENERGY STAR Compliance

HP products purchased with the ENERGY STAR configuration are compliant with the U.S. Environmental Protection
Agency (EPA) ENERGY STAR Computers Program. The EPA ENERGY STAR configuration does not imply endorsement
by the EPA. As an ENERGY STAR Partner, HP has determined that products with the ENERGY STAR configuration meet
the ENERGY STAR guidelines for energy efficiency.
The ENERGY STAR Computers Program was created by the EPA to promote energy efficiency and reduce air pollution
through more energy-efficient equipment in homes, offices, and factories. HP products achieve this by reducing the
power consumption when not being used.
ENERGY STAR on HP Workstations uses 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.
CAUTION: Using the Energy Save Monitor feature with non-ENERGY STAR-compliant monitors might cause video
distortion when the Energy Save timeout occurs.
