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 49. Note: For a device not supported by diagnostic codes in the ThinkPad Notebooks, see the manual for that device. Numeric error codes Table 2.
