Dell 5000 manual Before You Call

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 documentation is available.

CAUTION: To help prevent the risk of electrical shock, disconnect all exter- nal devices, remove the battery, and disconnect the AC adapter from the computer before installing or replacing the hard-disk drive and memory modules.
