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 1-4), your original configuration complied with these requirements and all Energy Star power management features of the computer are enabled. To disable or change the operation of these features, you must change the setting for the Power Management category in the System Setup program. For instructions, see Chapter 2, "Using the System Setup Program," or the online System User's Guide. 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 (such as installing additional expansion cards or drives) may increase the system's power consumption beyond the limits set by the EPA's Energy Star Computers program. TM Figure 1-4. 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. Important Notes to Windows 95 Users The following subsections apply only to systems running a Dell-installed Microsoft Windows 95 operating system. Reinstalling Windows 95 Dell configured your system to optimize the Microsoft Windows 95 operating system features. To ensure that all of these features are maintained on your system, you must use the version of Windows 95 that Dell installed on your hard-disk drive. In particular, versions of Windows 95 before 4.00.950 B do not contain bus-mastering EIDE support. Should you need to reinstall Windows 95 for any reason, you must be sure to reinstall the correct version. Dell recommends performing a periodic tape backup of the system's entire hard-disk drive so that, if necessary, the operating system, drivers, and other software can be reinstalled as originally configured, with a minimum of downtime. If you are unable to reinstall your software from a tape backup of the hard-disk drive, you can reinstall Windows 95 from the system's Windows 95 backup media (CD or diskettes) that you received from Dell or created from the Dell-installed software on your system. However, if you reinstall Windows 95 in this manner, the Windows 95 bus-mastering EIDE driver is installed but disabled. To enable this driver, see "Bus-Mastering EIDE Drivers for Windows 95" in the online System User's Guide. You may also need to reinstall other drivers after reinstalling Windows 95. See "Using Utilities and Drivers" in your online System User's Guide for more information. NOTE: If you are a network administrator of corporate networks and you must download Windows 95 from a server to client systems, make sure that you have the Windows 95 backup media for the OptiPlex Gn or Gn+ system on your server before downloading. 1-6 Dell OptiPlex Gn and Gn+ Low-Profile Systems Reference and Installation Guide
