132 Getting Help
Before You Call
NOTE: Have your Express Service Code ready when you call. The code helps Dell's automated-support telephone system
direct your call more efficiently.
Remember to fill out the Diagnostics Checklist. If possible, turn on your system before you call Dell for
technical 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 system itself. Ensure that the system documentation is available.
CAUTION: Before servicing any components inside your computer, see your Product Information Guide for
important safety information.
