Chapter 7. Symptom-to-FRU index The Symptom-to-FRU index lists error symptoms and possible causes. The most likely cause is listed first. Always begin with the Chapter 4 "General checkout" on page 35. You can use this index to help you decide which FRUs are needed when servicing a computer. If you are unable to correct the problem using this index, go to "Undetermined problems" on page 69. Notes: 1. If you have both an error message and an incorrect audio response, diagnose the error message first. 2. If you cannot run the diagnostic tests or you get a diagnostic error code when running a test, but did receive a POST error message, diagnose the POST error message first. 3. If you did not receive any error message, look for a description of your error symptoms in the first part of this index. 4. For computer models that do not have an internal hard disk drive and use a remote hard disk drive accessed through the SMC - Storage Array: • You might receive the error message "No operating system found. Press F1 to repeat boot sequence." In this case, press Ctrl+Alt+Delete instead of F1 to establish a connection to the storage area network where your operating system is stored. Verify that the user name is not logged on in another location. • If the SMC login prompt disappears before you log in and then a black screen displays, contact the administrator.
