  Introduction to Beep Codes or LED Codes on Dell Laptops

  Diagnostic indicators such as beep codes or LED codes are helpful to diagnose and resolve issues that your laptop might experience during start up.

  If the display cannot show any errors, your computer might emit a series of beeps during start-up.

  1. Three means 3-3-3-3…That is three beeps and three beeps and…: Endless looping until the user presses the power button to shut down the computer.
  2. The delay between each beep is 300 milliseconds. The delay between each set of beeps is three seconds, and the beep sound lasts 300 milliseconds.
  3. After each beep and each set of beeps, the BIOS should detect if the user presses the power button. If so, the BIOS jumps out from looping and performs the normal shutdown process and powers off the laptop.

  NOTE: See the documentation of your Dell laptop for device-specific information about diagnostic indicators such as beep codes or LED codes.

  NOTE: If your computer is giving a code that is not listed on this guide, see the documentation of your Dell laptop or contact Dell Technical Support to investigate this unknown code further.

  If your computer is giving a listed code, then use the fault descriptions below to narrow your possible No Post troubleshooting. For additional troubleshooting, learn How to Troubleshoot a No POST Issue on a Dell Laptop.

  Alternatively, for beep code or error codes related to the system memory or RAM, learn How to diagnose and resolve common memory issues on a Dell Laptop.

  If the computer passes the power-on self-test or POST, the computer may give a single beep (some computers may not beep or beep twice) as it starts and continues to boot. However, if the computer fails the POST, the computer may generate a beep code or LED code indicating the potential source of the problem.
