Checkout Guide

Use the following procedure as a guide for computer problems.

NOTE: The diagnostic tests are intended to test only IBM products. Non-IBM products, prototype cards, or modified options can give false errors and invalid system responses.

  1.  Obtain the failing symptoms in as much detail as possible.
  2.  Verify the symptoms by attempting to re-create the failure by running the  diagnostic test or by repeating the same operation.

    NOTE: To run the diagnostics, refer to 'Running the Diagnostics'.

  3.  Use the following table with the verified symptom to determine which page to go to.  Search the symptoms column, and find the description that best matches your symptom, then go to the page shown in  the 'Go To' column.
