This section covers troubleshooting information for the Compaq
Presario Series Portable Computers. The basic steps in
troubleshooting include:
1. Follow the Preliminary Steps.
2. Run the Power-On Self-Test (POST).
3. Follow the recommended actions described in the
diagnostic tables, if you are unable to run POST or if
POST displays an error message.
When following the recommended actions in the
Sections on POST and Diagnostic Error Codes perform
them in the order listed. Rerun POST after each
recommended action until the problem is solved and no
error message occurs. Once the problem is solved, do
not complete the remaining recommended actions.
NOTE:
If the problem is intermittent, check the
computer several times to verify that the
problem is solved.
