Before You Call
NOTE: Have your Express Service Code or service tag sequence 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 (Figure 4-1). 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 system itself. Make sure that the system doc umentation is
available .
CAUTION: To help prevent the risk of electrical s hock, disconnect all exter-
nal devices, remove the battery, and disconnect the AC adapter from the
computer before installing or replacing the hard-disk dri ve and memory
modules.
