Symptom-To-Fru Index; Numeric Error Codes - Lenovo ThinkPad R51e Series Hardware Maintenance Manual

Symptom-to-FRU index

Symptom-to-FRU index

The symptom-to-FRU index in this section 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 column headed "FRU or
action, in sequence." If replacing a FRU 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 likely 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 displayed, check the narrative
descriptions of symptoms. If the symptom is not described
there, go to "Intermittent problems" on page 70.
Note
For a device not supported by diagnostic codes in
the ThinkPad notebook computers, see the manual
for that device.
