Diagnostic Lights

To help you troubleshoot a problem, your computer is equipped with four lights labeled “A,” “B,” “C,” and “D.” Diagnostic lights are located on the back of the mini-tower computer and on the front of the desktop computer. When the computer starts normally, the lights flash. After the computer starts, all four lights will display solid green. If the computer malfunctions, the color and sequence of the lights identify the problem.
