Computer Beep Codes list and their meaning TIP: Download this tool to quickly find & fix Windows errors automatically A lot goes on when you boot up your computer. The first thing PC does is check if the hardware is working fine through its POST programme or Power On Self Test. It checks for hardware compatibility, and connections before going into the actual boot process. If you have noticed, as soon as you hit the power button, it sends out one BEEP, and then boots. This single beep is not a random thing. It signifies that everything is OK at the hardware level. So are there any other beep pattern? Yes, there is. Check out the Computer Beep codes list and their meaning.

Computer Beep Codes When the computer sends out more than one beep, it usually means that there is something wrong at the hardware level. The computer may not beep at all or may generate a series of beep in a fixed pattern. Some are continuous, while some have delays and mixed. Each pattern has a meaning which helps one to identify the problem. Some codes are very simple to troubleshoot, and you will be able to do it, and some will need a technician. Usually, the following are checked:  AC adapter  System board power  Processor failure  BIOS corruption  Memory failure  Graphics failure  System board failure  BIOS authentication failure Since there is no standard followed by all the OEMs for the beep. Every OEM have their own pattern, and hence we are listing the popular ones below.

Dell Beep Codes While the codes are listed below as 1, 2, 3 and so on, here is what it means. Beep Code 3 means that repeating series of 3 beeps with a small delay. When you shut down the PC, it will turn off the beep as well. Power LED Blinking/Beep Codes for Inspiron

HP Error Beep codes with Common Core BIOS HP Beep codes are a little different from usual. There are two types of Major and Minor. While Major points to the category of error, Minor is specific to the problem within the category i.e. long and short blinks, accompanied by long and short beeps

Number of long beeps/blinks

Error category

1

Not used; Single beep/blinks are not used

Number of long beeps/blinks 2 3 4 5

Error category BIOS Hardware Thermal System board

Patterns of blink/beep codes are determined by using the following parameters:  The 1-second pause occurs after the last major blink.  The 2-second pause occurs after the last minor blink.  Beep error code sequences occur for the first 5 iterations of the pattern and then stop.  Blink error code sequences continue until the computer is unplugged or the power button is pressed.
