Diagnostic Codes

Your system is equipped with four diagnostic code indicators, which are labeled "A," "B," "C," and "D" on the back of the computer. Each of the

four indicators can be yellow, green, or off as shown in Table 1. When the computer is turned on or restarted and the system is functioning normally,

the indicators flash during power-on self-test (POST). After the system starts, the indicators remain green to signify normal system operation.

If a malfunction is detected and the computer fails to start, the indicators display a code that identifies the problem. Write down the diagnostic code

displayed, and look it up in Table 1.
