Lenovo 3000 N200 Notebook - Manual (Page 41)

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 40.
Note
For a device not supported by diagnostic codes in the Lenovo 3000 notebook
computers, see the manual for that device.
