Obtaining Assistance
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 (see "Diagnostics Checklist" on page 153). 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.
CAUTION:
Before working inside your computer, read the safety instructions in your Product Information Guide .
