Troubleshooting Your System
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"
on page 180.
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 keyboard, mouse, or
other external device). Ensure that all external cables are securely attached to
the external connectors on your system. See Figure 1-6 for the front-panel
connectors on your system and Figure 1-9 for the back-panel connectors.
