Diagnostic Lights

CAUTION: Before you begin any of the procedures in this section, follow the safety instructions located in the Product Information Guide.

To help you troubleshoot a problem, your computer has four lights labeled "A," "B," "C," and "D" on the back panel (see page 50). The lights can be yellow or green. When the computer starts normally, the lights flash. After the computer starts, all four lights display solid green. If the computer malfunctions, the color and sequence of the lights identify the problem.
