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 front panel labeled "A," "B," "C," and "D." The 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.
