If you need to call Dell Computer Corporation for assistance, you will be able to inform the support technician of the actions you have taken to resolve the problem. If you must return a piece of hardware to Dell, a technician will assign a Return Material Authorization Number. Record the number on the checklist, and include the completed checklist in the shipping box. Dell's technical support staff uses computer-based diagnostics to provide fast, accurate answers to your questions. When you call, the technical support staff refers to records regarding your specific Dell system to better understand your particular question. NOTE: Have your express service code ready when you call. The code helps Dell's automated support telephone system direct your call more efficiently. If possible, turn your system on before you call Dell for technical assistance and call from a telephone at or near the system. You may be asked to type some commands at the keyboard, relay detailed information during operations, or try other troubleshooting steps possible only at the system itself. Make sure the system's user documentation is available. You should also have a flat-blade screwdriver or a quarter-inch nut driver available. WARNING: If you need to remove the computer cover, be sure to first disconnect the computer system's power and modem cables from all electrical outlets. 7-6 Diagnostics and Troubleshooting Guide

Dell’s technical support staff uses computer-based diag-
nostics to provide fast, accurate answers to your
