BIOS) A power-on self-test (POST) is a process performed by firmware or software routines immediately after a computer or gateway bios beep codes other digital electronic device is powered on. This article mainly deals with personal computers, but many other embedded systems such as those in major appliances, avionics, communications, or medical equipment also http://www.pchell.com/hardware/beepcodes.shtml have self-test routines which are automatically invoked at power-on. The results of tests run by the POST may be displayed on a panel that is part of the device, output to an external device, or stored for future retrieval by a diagnostic tool. Since a self-test might detect that the system's usual human-readable display is non-functional, an indicator lamp or a speaker https://en.wikipedia.org/wiki/Power-on_self-test may be provided to show error codes as a sequence of flashes or beeps. In addition to running tests, the POST process may also set the initial state of the device from firmware. In the case of a computer, the POST routines are part of a device's pre-boot sequence and only once they complete successfully is the bootstrap loader code invoked to load an operating system.

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. 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 desktop below. If 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 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. The No Post guide below will be useful in troubleshooting your issue further. No POST, No Power, No Video on a Dell Desktop Computer. Alternatively you can Contact Us here. Back to Top 2.
