Diagnostic Codes

Your computer 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 or green. When the computer is turned on or restarted and the computer is functioning normally, the indicators flash at the beginning of the start-up routine. After the computer boots (starts), all four of the indicators become green to signify normal computer operation.

If a malfunction is detected and the computer fails to boot, the indicators display a code that identifies the problem. In this situation, write down the diagnostic code displayed and look it up in Table 1. If the indicators display a code that is not illustrated in Table 1, contact Dell for instructions on obtaining technical assistance.
