Messages and Codes

Your application programs, operating system, and computer can identify 
problems and alert you to them. When a problem occurs, a message may 
appear on your monitor screen, a beep code may sound, or a light code may 
be generated. The following subsections present information about 
messages, beep codes, and light codes.

System Lights

Your computer has a number of lights that can help you analyze and solve 
problems. To locate these lights, see "Computer Features" on page 10.

The following table lists the codes for the system lights, gives probable 
causes, and suggests corrective actions.

 NOTE: For many system light codes, it is helpful to check the diagnostic lights 

to see if the specific problem is identified. See "Diagnostic Lights" on page 32.
