Chapter 8. Solving Problems
This chapter presents an overview of diagnostic tools available to you. You can use
these tools to identify and correct problems that might come up as you use your
computer. This chapter also contains information about option diskettes and
terminate-and-stay-resident (TSR) programs.
Important
If you have just added new software or a new computer option and your
computer is not working, do the following before using the other information in
the chapter:
� Remove the software or device you just added.
� Run the diagnostic programs to determine if your computer is running
correctly. (See “IBM Enhanced Diagnostics” on page 126 for information
about diagnostic programs provided with your computer.)
� Reinstall the new software or new device.
Using Diagnostic Tools
Computer problems can be caused by hardware, software, or user error (for
example, pressing the wrong key). Using the diagnostic aids discussed in this
chapter, you might be able to solve such problems yourself or gather helpful
information you can pass on to a service technician.
You can check the hardware by following the procedures in this chapter. You can
also use the diagnostic programs provided with your computer (see “IBM Enhanced
Diagnostics” on page 126 for a description of these programs).
If the hardware checks out OK, and you have not made a user error, you might
have a software problem. If you suspect that you have a software problem and
your computer came with IBM-preinstalled software, refer to About Your Software
and the operating-system documentation supplied with your computer. If you have
installed software applications yourself, consult the documentation supplied with
the software.
