Symptom-to-FRU Index

The symptom-to-FRU Index lists the symptoms and errors and the 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 WorkPad z50. Do not replace a nondefective FRU.

This index can also help you determine the next possible FRUs to be replaced when servicing the WorkPad z50.

Numeric error codes show the errors detected in system operation. In the following error codes, X can be any number. If no codes are available, use narrative symptoms. If the symptom is not listed, go to “Undetermined Problems” on page 26.

Note: For IBM devices not supported by diagnostic codes in WorkPad computers, see the manual for that device.
