A Reference Guide to Inspiron Desktop Diagnostic Indicators

Dell Inspiron Desktop systems have a long history of built-in diagnostic indicators. These can be audible beeps, power buttons that display different states and colors, specific diagnostics LEDs or a combination of them all. Indicating at which point during the Power On Self-Test (POST) a system is having issues.

The following article is a reference guide to the codes available on each model and what those codes mean. These changes through the various models and years. These indicators are merely a starting point to narrow down any troubleshooting you carry out to identify the cause of your current issue. You can use this as a starting point to narrow down the proper troubleshooting guide you need. Alternatively, you can contact technical support for further help and they are looking for these indicators as well.

  2. Diagnostic LEDs for the Inspiron Desktop series (2015 to 2019)

Note: For all the tables below, please remember that the diagnostic LEDs only serve as an indicator of the progress through the POST process. These LEDs do not indicate the problem that caused the POST routine to stop.
Note: Does your system complete POST without stopping on a particular error code and then gives a black screen? The most likely reason is that you are experiencing a No Boot issue and not a No POST issue at all.

Diagnostic LEDs for the Inspiron Desktop series (2020 to Present)

The tower systems that are currently being sold and supported has swapped over to an Amber blink code. This is common with Dell's notebook systems. The PLED is generally white.

Power Button LED Status Power State Description
SLN304440_en_US__5Vostro_off_PLED_BK01 Off S4 or S5 Power is Off. LED is blank.
SLN304440_en_US__6Vostro_blink_amber_PLED_BK01 Blinking Amber - Initial State of LED at power up. Refer to the table below for Blinking Amber pattern diagnostic suggestions and possible failures.
SLN304440_en_US__7Vostro_amber_PLED_BK01 Solid Amber - The second state of the LED at power up indicates that the POWER_GOOD signal is active and it is likely that the power supply is fine.
SLN304440_en_US__21Vostro_blink_white_PLED_BK01 Blinking White S1 or S3 System is in a low power state, either S1 or S3. This does not indicate a fault condition.
SLN304440_en_US__15Vostro_white_PLED_BK01 Solid White S0 System is in S0 state. This is the normal power states of a functioning machine. The BIOS turns the LED to this state to indicate it has started fetching op-codes.
Note: You can customize the power-button behavior in Power Options. For more information, see Me and My Dell at www.dell.com/support/manuals.

Inspiron 3880, 3881, etc.

Note: The blinking patterns consists of 2 sets of numbers. They split into First Group(Amber Blinks), Second Group(Amber Blinks).
  • First Group: The Battery LED blinks in Amber up to 9 times then pauses for 1.5 seconds before running the second group.
  • Second Group: The Battery LED blinks in Amber up to 9 times then pauses for 3 seconds before running the first group again.

Example: No Memory detected (2,3), The Battery LED blinks two times amber followed by a pause, then blinks three times Amber, pause, etc. This pattern continues until the system is powered off.
