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 9). The lights can be yellow or green. When the computer starts normally,
the patterns or codes on the lights change as the boot process completes. If the POST portion of
system boot completes successfully, all four lights display solid green. If the computer malfunctions
during the POST process, the pattern displayed on the lights may help identify where in the
process the computer halted.
