Error Messages
Error Messages
Error messages indicate that a problem exists; they are not intended
to be used to identify a failing part. Troubleshooting and servicing
of complex problems indicated by these error messages should be
performed by a trained service technician.
Types of Messages
System problems can result in two types of error messages — POST
and diagnostic:
Ÿ POST error messages appear when, during startup, POST finds
problems with the hardware or detects a change in the
hardware configuration.
Ÿ
Diagnostic error messages appear when the Test the Computer
program or Diagnostic program finds a problem with hardware.
Messages generated by your software—the operating system or
application programs—generally are text messages, but they also
can be numeric. Information about these messages is not included
in this handbook. For information about these error messages, refer
to the documentation that comes with your software.
Multiple Messages
Sometimes the first error to occur causes additional errors. In this
case, the system displays more than one error message. Always
follow the suggested action instructions for the first error message
that appears.
