Numeric Error Codes - Lenovo ThinkPad E490s Hardware Maintenance Manual

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 38.
Note: For a device not supported by diagnostic codes in the ThinkPad notebook computers, see the manual
for that device.
