Beep Codes on a Dell Desktop PC This article is a guide to the various diagnostics Beep Codes used by the various Dell Desktop PCs. Table of Contents: Introduction to Beep Codes Dell Desktop Systems 1. Introduction to Beep Codes Dell has a long tradition of building diagnostic indicators into our systems. dell laptop beep codes These indicators can be really useful in helping to diagnose and resolve any issues dell error codes lights your PC might experience whilst starting up. I've given a guide to the various codes for each family of desktop below. If dell beep codes 5 the display cannot show any errors your computer might emit a series of beeps during start-up. 3 means 3-3-3-3...That is 3 beeps and 3 beeps and ...: Endless looping until user presses the power button to dell inspiron beep codes 4 beeps shut down the system. The delay between each beep is 300ms. The delay between each set of beeps is 3 sec, and the beep sound lasts 300ms. 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.

Power Button LED shall blink the corresponding LED codes for the corresponding fault dell dimension beep codes condition. Example: No Memory detected, Power Button LED blinks two times followed by a pause, blinks two times, pause, dell xps beep codes etc. This pattern continues until the system is powered off. LED Code Fault Description Suggested Remedy 1 System Board: BIOS ROM failure System board, covers BIOS corruption or ROM error 2 Memory No http://www.dell.com/support/article/us/en/19/SLN293445 memory/RAM detected 3 System board failure Chipset Error Clock failure Gate A20 failure Super I/O failure Keyboard controller failure System board failure 4 Memory Memory/RAM failure 5 Real-time clock failure Reseat the CMOS battery connection If the problem persists, possible battery failure or system board failure 6 Video BIOS Video card/chip failure 7 CPU Processor failure 8 LCD LCD failure Diagnostic Beep Codes The computer may http://www.dell.com/support/article/us/en/19/SLN290715 emit a series of beeps during start-up if the display cannot show errors or problems. These series of beeps, called beep codes, identify various problems. The delay between each beep is 300 ms, the delay between each set of beeps is 3 seconds, and the beep sound lasts 300 ms. 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. Beep Code Fault Description Suggested Remedy 1 BIOS ROM checksum in progress or failure System board failure, covers BIOS corruption or ROM error 2 Memory No memory/RAM detected 3 Chipset Error (North and South bridge error, DMA/IMR/Timer error) Time-Of-Day Clock test failure Gate A20 failure Super I/O failure Keyboard controller failure System board failure 4 RAM Read/Write failure Memory/RAM failure 5 Real-time clock power fail Reseat the CMOS battery connection If the problem persists, possible battery failure or system board failure 6 Video BIOS Test Failure Video card/chip failure 7 CPU-cache test failure Processor failure 8 LCD LCD failure Click the button below to Tweet feedback or request assista

If the test identifies a hardware problem, the BIOS will display an error message on the monitor. But, if the failure occurred before the BIOS could access the video card, the BIOS will issue special beep codes to alert the user to the problem.In this article, I'll take a detailed look at the beeps that are issued by various BIOS manufacturers, and I'll provide you with a resource for more detailed information. Understanding these noises will allow you to troubleshoot a multitude of hardware problems.Annoying noises, flashing lightsDuring a POST session, your computer has several ways to communicate: Either through flashing indicator lights, the computer's speaker, or via the monitor. Since the monitor is not initialized until later in the process, early failures are communicated by red or absent status lights, such as the power and hard drive activity lights, or by sound in the form of beeps.POST diagnostic cards Another option is to purchase a POST diagnostic card to intercept
