Appendix C: Troubleshooting

This appendix provides information on pinpointing and solving common
problems that you may encounter using the notebook.
Problems with your notebook can be caused by something as minor as an
unplugged power cord or as major as a damaged hard disk drive. The information
in this appendix is designed to help you find and solve minor problems. If you
still have a problem after trying all the suggested remedies in this appendix
contact your dealer.
The problems that you might encounter can be divided into two basic categories:
hardware and software. Hardware problems can be further divided into being of
an electrical or a mechanical nature. You will know you have a hardware problem
if, for example, the screen is blank, the notebook cannot recognize the disk drives,
or you get an error message during the Power-On Self Test (POST).
Software problems can occur at several levels. Both your operating system and
your software application programs are capable of generating errors and error
messages. If you encounter a software error, try to determine if the error message
is from your operating system or from an application program, and refer to the
appropriate manual for possible remedies.
You can also refer to the Windows 95 manual of Windows Help program to solve
the problem. To access the Help program, click the Start button, then point to
Help. It also gives you Troubleshooting tips and an Index.
Common Problems
Successful troubleshooting is the result of careful observation, deductive
reasoning, and an organized approach to solving the problem. If you encounter a
problem, begin by performing a careful visual inspection. Check the exterior of
the notebook first. If no lights are displayed, check the battery charge or power
outlet, the plug and power cord, and any power switches that may affect your
notebook. If the notebook has been connected to any peripheral devices, look for
loose or disconnected cables. You may also need to check the fuses and breakers
in your electric box.
