ENERGY STAR Qualification
HP computers marked with the ENERGY STAR logo are compliant with the applicable U.S.
Environmental Protection Agency (EPA) ENERGY STAR specifications for computers. The EPA ENERGY
STAR logo does not imply endorsement by the EPA. As an ENERGY STAR Partner, Hewlett-Packard
Company has determined the products marked with the ENERGY STAR logo are ENERGY STAR
qualified per the applicable ENERGY STAR guidelines for energy efficiency. The following logo
appears on all ENERGY STAR qualified computers.
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. One way
products achieve this energy efficiency is by reducing power consumption when not being used through
the Microsoft Windows Power Management feature.
The Power Management feature enables the computer to enter a low-power (or "sleep") mode after a
period of inactivity. When used with an external monitor that is ENERGY STAR qualified, this feature
also supports the similar power management features of the external monitor.
To take advantage of this energy savings:
The Power Management feature has been preset to suspend the computer to a sleep state after 30
minutes of inactivity.
The Power Management feature has been preset to suspend the monitor to a sleep state after 15
minutes of inactivity.
Both the computer and monitor can be woken from sleep mode through user interaction with any of the
computer input devices (mouse, keyboard, and so on). when configured with Wake On LAN (WOL)
enabled, the computer can also be woken by a network signal.
See the EPA ENERGY STAR Power Management Web site for more information about the energy and
financial savings potential of the Power Management Feature:

qualified can cause video distortion when an Energy Save timeout occurs.
ENERGY STAR is not supported on Linux computers.
If it is necessary to restore the operating system, you must also reset the ENERGY STAR settings (if
applicable) after the restore.
To verify the factory default power settings for your computer, select Start>Control Panel, and then
double-click Power Options.
