Before upgrading your computer The upgrading procedures described in this section assume that you are familiar with the general terminology associated with personal computers and with the safety practices and regulatory compliance required for using and modifying electronic equipment. Disconnect the computer from its power source and from telecommunications links, networks, or modems before you open the unit or follow any procedures described in this section. Failure to disconnect your computer from its power source may result in personal injury or equipment damage. Your computer may not be equipped with all of the hardware features mentioned in this section. The interior configuration of your system may vary from the illustrations, depending on the computer purchased. Electrostatic discharge (ESD) can damage disk drives, add-on cards, and other components. Follow the procedures described in this section, only at an ESD workstation. If such a station is not available, do not work in a carpeted area and do not handle materials that produce or hold static electricity (for example, cellophane wrappers). Ground yourself by maintaining continuous contact with an unpainted metal portion of the chassis while performing the procedure. Always turn the power off before you open the system or connect your computer to peripheral equipment. Otherwise, damage may occur to the integrated circuits in your computer. Page 76
