Each LED has three possible states: OFF, ON, or BLINKING. Use the chart below as a reference for the different LED patterns and the possible system issues they indicate. Note: The diagnostic LEDs only serve as an indicator of the progress through the POST (Power On Self-Test) process. These LEDs do not indicate the problem that caused the POST routine to stop. For a more detailed description of the POST process http://www.dell.com/support/article/us/en/04/SLN288973/en and how to troubleshoot issues with the system powering on and booting to Windows, refer to the article Why Won't my Desktop Computer Turn On? at the Dell support site.

Blinking amber Initial state of LED at power up.Indicates system has power, but the POWER_GOOD signal is not yet active.If the Hard Drive LED is off, it is probable that the power supply needs to be replaced.If the Hard Drive LED is on, it is probable that an onboard regulator or VRM has failed. Look at the diagnostic LEDs for further information. Solid amber Second state of the LED at power up. Indicates the POWER_GOOD signal is active and it is probable that the power supply is fine. Look at the diagnostic LEDs for further information. Blinking white System is in a low power state, either S1 or S3. Look at the diagnostic LEDs to determine which state the system is in. Solid white System is in S0 state, the normal power state of a functioning machine.The BIOS will turn the LED to this state to indicate it has started fetching operation codes.Back to Top 3.
