Dell is the first PC manufacturer to achieve Energy Star 4.0 requirements with its new Inspiron 531. Some of its features are a 80% efficient power supply and a paperless owners manual. The computer is also pre-programmed to switch to a low-power sleet state after 15 minutes of inactivity.
Dell Inspiron 531 comes with an AMD Athlon-64 X2 dual-core processor, 1GB of DDR2 memory, 160GB hard drive, CD-RW/DVD-ROM combo drive, nVidia integrated graphics and Windows Vista Home Basic as operating system.
EPA, the U.S. Environmental Protection Agency, estimates that with the latest update of Energy Star requirements only the top 25% of energy-efficient computers will qualify Energy Star 4.0.
