Diagnostic Codes

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

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

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

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

displayed and look it up in Table 1.
