Security Cable Slot and Padlock Ring On the back of the computer are a security cable slot and padlock ring (see Figure 1-2) for attaching commercially available antitheft devices. Antitheft devices for personal computers usually include a segment of galvanized cable with an attached locking device and key. To prevent unauthorized removal of your computer, loop the cable around an immovable object, insert the locking device into the security cable slot on the back of your computer, and lock the device with the key provided. Complete instructions for installing this kind of antitheft device are usually included with the device. NOTE: Antitheft devices are of differing designs. Before purchasing such a device, make sure it will work with the cable slot on your computer. The padlock ring allows you to secure the computer cover to the chassis to prevent unauthorized internal access. To use the padlock ring, insert a commercially available padlock through the ring and lock the padlock. Energy Star Compliance 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 1-3), 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 this product meets 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.

Energy Star Emblem 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.
