Troubleshooting
This chapter covers troubleshooting and resolving common problems associated with
Compaq Presario 1800XL Series Notebooks. The basic steps in troubleshooting include:
1. Preparing the Notebook for troubleshooting as outlined in Preliminary Steps on the
following page.
2. Performing the Power-On Self-Test (POST) and observing any error messages
displayed.
Note: If the Notebook is unable to complete POST or an error message is displayed, skip
to Step 3 below to try to resolve the problem.
3. Taking the recommended steps described later in this chapter to solve the problems.
When following the recommended actions provided in POST and Diagnostic Error Codes,
perform the steps in the order listed above. Rerun POST after each recommended action
until the problem is solved, even if no error message occurs. Once the prob lem is solved,
do not perform any remaining recommended solutions.
Note: If the problem is intermittent, check the Notebook several times to be sure that
the problem is resolved.
