Diagnostic Lights

To help troubleshoot a problem, your computer has four lights on the back panel labeled "A","B","C," and "D." These lights can be either yellow or green. When the computer starts normally, the patterns or codes on the lights will change as the boot process completes. If the POST portion of system boot completes successfully, all four lights will 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."
