Troubleshooting External Connections
Loose or improperly connected cables are the most likely source of problems for
the system, monitor, and other peripherals (such as a printer, keyboard, mouse,
or other external device). Ensure that all external cables are securely attached to

connectors and Figure 1-2 for the back-panel connectors on your system.
