Checklist for Solving Problems
If you encounter a minor problem with the computer or software applications, go
through the following checklist for possible solutions:
■ Is the computer connected to an external power source, or does it have a fully
charged battery pack installed?
■ Are all cables connected properly and securely?
■ Did the diskette drive contain a nonbootable diskette when you turned on the
computer?
■ Have you installed all the needed device drivers? For example, if you are using a
mouse, you may need to install a mouse device driver.
■ Are printer drivers installed for each application?
Eliminating the typical problems described in this Troubleshooting section may save
you time and money. If the problem appears related to a software application, check the
documentation provided with the software. You may discover something you can
resolve easily by yourself.
If the condition persists, contact your Compaq authorized dealer or service provider.
