Before You Call
Remember to fill out the Diagnostics Checklist (see Diagnostics Checklist ). If possible, turn on your computer before you call Dell for assistance and call from a
telephone at or near the computer. 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 computer itself. Ensure that the computer documentation is available.
