Certain configurations of Dell computer systems comply with the requirements set forth by the Environmental Protection Agency (EPA) for energy-efficient computers. If the front panel of your computer bears the Energy Star Emblem (see Figure 1-4), your original configuration complied with these requirements and all Energy Star power management features of the computer are enabled. NOTES: As an Energy Star Partner, Dell Computer Corporation has determined that these products meet the Energy Star guidelines for energy efficiency. Any Dell computer bearing the Energy Star Emblem is certified to comply with EPA Energy Star requirements as configured when shipped by Dell. Any changes you make to this configuration may increase the system's power consumption beyond the limits set by the EPA's Energy Star Computers program. TM The EPA's Energy Star Computers program is a joint effort between the EPA and computer manufacturers to reduce air pollution by promoting energy-efficient computer products. The EPA estimates that use of Energy Star computer products can save computer users up to two billion dollars annually in electricity costs. In turn, this reduction in electricity usage can reduce emissions of carbon dioxide, the gas primarily responsible for the greenhouse effect, and sulfur dioxide and nitrogen oxides, which are the two primary causes of acid rain. Computer users can also help to reduce electricity usage and its side effects by turning off their computer systems when they are not in use for extended periods of time-particularly at night and on weekends. 1-6 Dell OptiPlex NX1 Net PC Systems User's Guide
