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 front panel. The lights can be yellow, green, or off. 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.
