Power-on self-test (POST)

When you turn on the computer, it performs a series of tests to check the operation
of system components and some of the optional devices in the computer. This
series of tests is called the power-on self-test, or POST.
If a power-on password is set, you must type the password and press Enter, when
your are prompted, for POST to run.
If POST is completed without detecting any problems, a single beep sounds, and
the computer startup is completed.
If POST detects a problem, more than one beep might sound, or an error message
is displayed. See "Beep code descriptions" in the Problem Determination and
Service Guide and "POST error codes" in this document for more information.

POST beep codes

A beep code is a combination of short and long beeps, or a series of short beeps,
separated by pauses (intervals without sound). For example, a "1-2-3" beep code is
one short beep, a pause, two short beeps, a pause, and three short beeps. A beep
code other than one beep indicates that the POST process has detected a problem.
To determine the meaning of a beep code, see "Beep code descriptions" in the
Problem Determination and Service Guide on the IBM IntelliStation Documentation
CD. If no beep code sounds, see "No-beep symptoms" in the Problem
Determination and Service Guide.

POST error codes

The following table provides an abbreviated list of the POST error codes that might
appear during startup. See the Problem Determination and Service Guide on the
IBM IntelliStation Documentation CD for more information about the POST error
codes.
