What Is A Beep Code?
In the first time that a computer starts up, it operates a Power-On Self Test (POST) and will present an error message on the screen if there is any problem.
But, if BIOS meets a problem yet has not booted far adequate to be able to show off a POST error message on the screen, then a beep code, which is an audible version of the error message, will do instead.
Beep codes are particularly useful if the underlying cause of the issue originates or partly involves with a video. If you could not read an error code or error message on the monitor due to a video-related issue, it will deter your attempts of finding out what is going wrong. This explains why having the option to be able to hear the errors as a beep code is incredibly useful.
Understanding POST Beep Codes
If your computer does not start up but makes beep noises, then the first thing you had better do is to refer your motherboard or computer manual for translating beep codes into something meaningful, like a particular issue which is happening.
Whilst there are not too many BIOS producers in the market, each producer has their specific set of beep codes. They may use different patterns along with beep lengths – some are short, some are long or something else in between.
Therefore, the same beep sound on two separate computes may express two different issues.
Look at the wrong producer’s beep code information may have you thinking that those beeps might be related to the hard drive instead of another, which will set you off on the wrong solutions of troubleshooting.
On most computers, the BIOS of motherboards produces a single, or double short beep code as a type of an indication showing that the hardware tests turned into normal – “all systems clear”. This beep code is not a problem needed troubleshooting.
What If There Is No Beep Sound?
In case there is no beep sound, then there might still be hope.
Chances are, no beep code means that your computer does not possess an internal speaker, meaning that it will not be able to hear anything, even when the BIOS produces it. In such cases, the solution is to use a POST test card in order to see the error message in the digital form.
The next reason why you do not hear beep sound is that the power supply of your computer is bad, therefore beep sounds are unable to be made.
