How to Use Error Messages:
Use the error codes displayed on the screen to diagnose failures.
If more than one error code is displayed, begin the diagnosis with the first error code. Whatever caused the first error code can result in false error codes being displayed. If no error code is displayed, see if the error symptom is listed in the 'Symptom-to-FRU Index'.
Port Replicator Problems:
If you suspect a problem with the port replicator, see 'Port Replicator Checkout'.
