Dell today extended its commitment to becoming the "greenest" technology company on Earth with the addition of an Energy Star 4.0-compliant desktop that helps consumers reduce their carbon footprint. The specially configured Inspiron 531 is Dell's first consumer PC to meet the Energy Star 4.0 requirements. Powered by an 80 percent efficient power supply, the system comes pre-configured to switch to a low-power sleep state after 15 minutes of inactivity and also includes a forest-friendly paperless owner's manual. Using an energy-efficient desktop with a flat panel monitor for four years can reduce carbon dioxide (C02) emissions by approximately the same amount as not driving a car for eight weeks. With a starting price of $369, the Inspiron 531 is available to U.S. customers immediately. Entry-level configurations include an AMD Athlon 64 X2 dual-core processor, 1GB2 DDR memory, 160GB hard drive, CDRW / DVD combination drive, NVIDIA integrated graphics, Windows Vista Home Basic, and one year Limited Warranty with In-Home Service and support.
