This chapter describes locating and solving problems that you may encounter while using your
computer.
Locating a Problem
Problems with your computer can be caused by something as minor as an unplugged power
cord – or as major as a damaged hard disk. The information in this chapter is designed to help
you find and solve minor problems. If you try all the suggested solutions and you still have a
problem, make a list of what steps you have taken to correct the problem and contact your dealer.
Successful troubleshooting is the result of careful observation, deductive reasoning, and an
organized approach to solving the problem.
The problems that you will encounter can be divided into two basic categories: hardware
problems and software problems. Hardware problems can be further divided into electrical and
mechanical problems. You will know you have a hardware problem if the screen is dark, the
computer cannot read the disk drives, or you get an error message during the Power-On Self Test
(POST).
Software errors can occur at several levels. The ROM BIOS and the operating system can give
you a large number of error messages. On top of this, each application software package has its
own set of error messages. It is important to determine whether the software error message you
are getting is from the application or the operating system. Once you know this, you can look in
the respective manual for a solution to the problem.
Checking Cables and Connections
Start by performing a careful visual inspection of the exterior of the computer. If no LEDs are
illuminated, make sure that your computer and its peripherals are getting power and communicating
with each other properly.
