Introduction to Beep Codes

Dell has a long tradition of building diagnostic indicators into our systems. These indicators can be really useful in helping to diagnose and resolve any issues your PC might experience whilst starting up. I've given a guide to the various codes for each family of notebook below.

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

  1. 3 means 3-3-3-3...That is 3 beeps and 3 beeps and ...: Endless looping until user presses the power button to shut down the system.

  2. The delay between each beep is 300ms. The delay between each set of beeps is 3 sec, and the beep sound lasts 300ms.

  3. After each beep and each set of beeps, the BIOS should detect if the user presses the power button, if so, BIOS will jump out from looping and execute the normal shutdown process and power system.

Note: If your system also has diagnostic indicator LEDs, you will want to go to the support site to get the appropriate guide for your model.
Note: If your system is giving a code that isn't listed on this guide, then please contact your local support to investigate this unknown code further.

If your system is giving a listed code then please use the fault descriptions below to narrow your possible No Post troubleshooting. The No Post guide below will be useful in troubleshooting your issue further.

Note: Depending on the hardware configuration of your system, you may need speakers connected to the output connecter in order to hear the beeps. If your system does not emit any beeps in a repeated pattern, please check out the guides below for what the diagnostic LEDs mean on your PC instead.
