DELL 580 用户手册

NOTE: Have your Express Service Code 

ready when you call. The code helps Dell’s 

automated‑support telephone system direct 

your call more efficiently. You may also be 

asked for your Service Tag.

Remember to fill out the following Diagnostic 

Checklist. 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.
