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.
