PROBLEM
DETERMINATION
PROCEDURES
~
Introduction
If
you experience a problem with either your IBM
Personal Computer or IBM Personal Computer XT, the
problem determination procedures will help you find
which unit in your system is failing. The procedures
also can be used to check that your system
is
operating
correctly. Simply follow the step-by-step instructions
and answer yes
or
no
to
the questions asked.
As part of the problem determination, you may have to
use the Diagnostics diskette, which is at the back of the
manual. The diskette has a series of tests that check
the five units of your
system-system
unit, expansion
unit, keyboard, display, and
printer-as
well as other
installed options. The tests are performed in sequence.
As one test finishes successfully, the next one
automatically starts.
Note:
If
you have a non-U.S. English keyboard and
use the diskette in the back of this manual, use a
U.S. English keyboard template.
For
a screen-alignment problem, start
on
the following
page.
To
do a complete system check or find the cause
of a problem, start with "Checking Electrical
Connections"
on
page Start 20-1.
Other Options
Some options may have separate manuals.
For
a
description of problem diagnosis, go to that option's
manual.
