Beep Codes

Your computer might emit a series of beeps that identify a problem. One
possible series (code 1-3-1) consists of one beep, a burst of three beeps, and
then one beep. This series tell you that the computer encountered a
memory problem.
If a beep code is emitted, write it down and look it up under "Beep Codes"
in the User’s Guide.

Error Messages

NOTE: If the message is
not listed, see the
documentation for either
the operating system or
the program that was
running when the message
appeared.
If an error occurs during start-up, a message may be displayed on the
monitor identifying the problem. See "Error Messages" in the User’s Guide
for suggestions on resolving any problems.

Diagnostic Lights

To help you troubleshoot a problem, your computer is equipped with four
lights on the back panel labeled "A," "B," "C," and "D". These lights can be
yellow or green. When the computer starts normally, the lights flash. After
the computer starts, the lights remain green. If the computer malfunctions,
the color and sequence of the lights identify the problem.
