Checking the Equipment
This section provides troubleshooting procedures for external devices attached to the system, such
as the monitor, keyboard, or mouse. Before you perform any of the procedures, see
"Troubleshooting External Connections."
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 the external connectors on your system. See
Figure 2-5 for the back-panel connectors on your system.
