Quick Reference Guide
To help you troubleshoot a problem, your computer has four lights labeled
"1," "2," "3," and "4" on the front panel. The lights can be off 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.
NOTE:
The orientation of the diagnostic lights may vary depending on the system
type. The diagnostic lights can appear either vertical or horizontal.
