ENERGY STAR® Compliance

Desktops, Notebooks, and Workstations
manufactured after July 20, 2007 that bear the
ENERGY STAR label meet the more advanced 4.0
requirements. Because of these requirements, your
computer has a more efficient power supply and
other features that could annually:
Save you 130 kWh of electricity.
Prevent 200 lbs of green house gas emissions (enough to fill
a large room).
However, this computer can save even more energy due to ENERGY
STAR power management features, which allow the computer to
enter a very low power mode when not in use for a specified period
of time. These power management features, activated on all ENERGY
STAR qualified computers, could save you up to 500kWh of electricity
annually, equivalent to:
Preventing as much greenhouse gas emissions as taking
your car off the road for 3 weeks.
Planting a grove of trees 70ft. by 70ft.
Additional power management specific information is available at
www.energystar.gov/powermanagement.
