During the repair process of the PC you're going to find many situations, one may be flaws with any device and you probably do not have clarity of the proper way to detect these faults effectively.
If you pay attention to what I am going to explain you will learn the basic operation of the BIOS and its usefulness as a diagnostic tool during PC repair.
The BIOS is a program that is loaded in ROM (read only memory), which at the time of turning on the PC or restart it performs a check of the hardware that is connected to it.
During this process really makes a diagnosis which is commonly called POST or Power On Self Test, understand which is very important to consider when trying to establish a process failures in the PC repair.
What is the BIOS performs a check of our equipment works properly.
For which performs checking different elements as:
- Check that the values of the stresses or energy reaching our team and its various components is correct.
- Check that the RAM and CACHE memory we have installed this in perfect order.
- Check all configurations of different devices such as keyboard, hard drive, mouse and other devices installed in our computer.
But this does not end all, the most important is that if the BIOS during the POST detects a problem with any device, if the error is serious stop system load and show us a message on the screen, accompanied by a message or audible sounds that allow us to know if a high percentage detect the origin of the failure.
Then you will know what I mean when I say that it is very valuable to know how it works the BIOS and have on hand what each one of those sounds and messages that give us to know the BIOS, as an element of diagnosis to repair the PC so affective.
It is important to note that different sequences of sounds depending on the BIOS manufacturer, among the best known manufacturers are:
You can access the code information of the corresponding BIOS if you go to the manual on the main board to know that code corresponds to the device in trouble, but anyway I'll give some general codes that could help you during repair PC.
The main error codes are:
Beep and meanings
No Sound: No power, verify that the power cord is connected properly, or it may be that the speakers are bad and no sound is heard.
Steady Sound. Error in power supply, bad is coming along.
Sound long. Error of RAM, it is normal that is misplaced or is bad
- short sound: Error graphic controller unit or possible error of RAM.
- sounds brief: memory parity error
- short sounds: RAM error
- short sounds. Error on the clock on the system board or motherboard.
- short sounds: This indicates that the processor or graphics card are blocked. It happens with overheating.
- short sounds. Error in the keyboard or keyboard controller. 1 long beep, one short beep: error on the motherboard1 long beep, 2 short beeps: Graphics controller error
You know the next time you turn on the PC correctly, then proceeds to carefully analyze the possible cause, taking into account the guidance I just gave you, most certainly can detect the fault and correct it.
