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.
