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
computer 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 itself. Make
sure that the computer documentation is available.
CAUTION: Before servicing any components inside your computer,
see “ Safety First—For You and Your Computer .”
