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

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.
CAUTION: Before you begin any of the procedures in this section,
follow the safety instructions in the System Information Guide.
