Troubleshooting External Connections
Loose or improperly connected cables are the most likely source of problems

mouse, or other external device). Ensure that all external cables are securely
attached to the external connectors on your system. See "Front Panel Features
and Indicators" on page 13 and "Back Panel Features and Indicators" on
page 19 for the front and back panel connectors on your system.
