Symptom-to-FRU Index
The symptom-to-FRU index lists the symptoms and errors and their possible
causes. The most likely cause is listed first.
Note:
Perform the FRU replacement or actions in the sequence shown
in the “FRU/Action” columns. If a FRU replacement did not solve
the problem, put the original part back in the computer. Do not
replace a nondefective FRU.
This index can also help you determine the next possible FRU to be replaced
when servicing a computer.
Numeric error codes show the errors detected in POST or system operation.
If no codes are available, use narrative symptoms.
If the symptom is not listed, go to “Undetermined Problems”.
Numeric Error Codes
The following is a list of the messages that the BIOS can display. Most of
them occur during POST. Some of them display information about a hardware
device, e.g., the amount of memory installed. Others may indicate a problem
with a device, such as the way it has been configured. Following the list are
explanations of the messages and remedies for the reported problems.
Note:
If the system fails after you make changes in the Setup menus,
reset the computer, enter Setup and install Setup defaults or
correct the error.
