Troubleshooting Your Computer; Diagnostics; Diagnostic Error Messages - Dell Vostro 3667 Owner's Manual

You can troubleshoot your computer using indicators like diagnostic lights, beep codes, and error messages during the operation of the
computer.

Diagnostics

The computer POST (Power On Self Test) ensures that it meets the basic computer requirements and the hardware is working
appropriately before the boot process begins. If the computer passes the POST, the computer continues to start in a normal mode.
However, if the computer fails the POST, the computer emits a series of LED codes during the start-up. The system LED is integrated on
the Power button.
The following table shows different light patterns and what they indicate.
