Diagnostic tools overview
If Power-On Status is set to [Enabled] and POST detects a problem,
you will hear multiple beeps or no beep. In most cases, an error
code appears in the top left corner of the screen, and in some cases,
a description of the error is displayed beside the code. (Note that
the screen will sometimes display multiple error codes and
descriptions.) For more information about what caused an error
message to appear and what action to take, see “Power-on self-test
(POST) messages” on page 165 and “POST message table” on
page 169.
POST beep codes
If Power-On Status is set to [Enabled], POST also generates beep
codes to indicate successful completion or the detection of an error.
Ÿ
The startup of the operating system or application program
indicates successful completion of POST.
Ÿ
More than one beep indicates that POST detected an error. For
more information, see “Power-on self-test (POST) beep codes”
on page 192.
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 error messages should be
performed by a trained service technician.
Hardware error messages that occur can be text, numeric, or both.
Messages generated by your software generally are text messages,
but they also can be numeric.
