Diagnostic Lights
To help you troubleshoot a problem, your computer has four lights labeled "1," "2," "3," and "4" on the front or back 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.
1-2-3 (on) 4 (off)
A failure has occurred. This pattern also displays when you enter system setup (see Entering System Setup) and may not indicate a problem.
Ensure that the cables are properly connected to the system board from the hard drive, CD drive, and DVD drive.
Check the computer message that appears on your monitor screen.
If the problem persists, contact Dell (see Contacting Dell).
Beep Codes
Your computer might emit a series of beeps during start-up if the monitor cannot display errors or problems. This series of beeps, called a beep code, identifies a problem. One possible beep code (code 1-3-1) consists of one beep, a burst of three beeps, and then one beep. This beep code tells you that the computer encountered a memory problem.
