Diagnostic Lights

To help you troubleshoot a problem, your computer has four lights labeled "A," "B," "C," and "D" on the back panel. 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 LEDs may help identify
where in the process the computer halted.

CAUTION:

Before you begin any of the procedures in this section, follow the steps in "

CAUTION: Safety Instructions

."
