Symptom-to-FRU index
Symptom-to-FRU index
The symptom-to-FRU index lists symptoms and errors and
their possible causes. The most likely cause is listed first,
in boldface type.
Note
Do the FRU replacement or other actions in the
sequence shown in the “FRU/Action in Sequence”
column. If a FRU replacement does 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, during regular
servicing, what FRUs are liking to need to be replaced
next.
A numeric error is displayed for each error detected in
POST or system operation. In the displays, n can be any
number.
If no numeric code is presented, check the narrative
description of symptoms. If the symptom is not described
there, go to “Intermittent problems” on page 46.
Note
For IBM devices not supported by diagnostic codes in
the ThinkPad notebook computers, see the manual for
that device.
