Guide: How reset BIOS, setup or motherboard (CLR CMOS Jumper)

BIOS (basic input/output system, the software including any motherboard, which are the configurations of the same, such as: order boot, peripherals, time, etc.) can protect you with a password, so that nobody without authorisation between and Unconfigure the team. But sometimes we forget the password that we have assigned and entered in a ‘cycle of complication’.

Just remember that different things we set in the BIOS (or SETUP of your computer):

Order of the boot of the equipoPuertos, peripherals, etc.Optical drives, hard drives, etc.The temperaturaLa time of computer display

Now well many times we need to reset the BIOS because the team introduces conflicts with other things, as for example, do not want to boot because it desconfiguró, or because you have installed a new peripheral, with incompatibility. In the reset the BIOS, the configuration of the motherboard, gets as factory, i.e. as her they configured for the first time.

To reset the BIOS, the team is as factory, even with the date on which its configuration was realized. The truth is that reset the BIOS is not nothing complicated, just one removed from the corresponding jumper on the motherboard, and with that, we will succeed. What is a jumper? According to Wikipedia it is ‘an element to interconnect two terminals on a temporary basis without having to perform an operation that requires additional tool’. The concept is rather clear, and the procedure for the reset of the BIOS, is quite simple.

To reset the BIOS, have an area on the motherboard which, usually has a name called «clr cmos» or «clcmos», meaning «clear cmos» (clear CMOS), and is composed of three pins. The jumper is connected on two of these pins, and we have to do is disconnect it, pass it on to the other 2 pins, and bring them to the initial PIN.

In the next picture, it is apparent how is the appearance of the CLR CMOS jumper:

And well, as you can see in this image the jumper is change of position to be then taken to the same position, obtaining in this way that the BIOS is reset. Therefore, as it is common, many will wonder how you can get these pin on your card, and the truth is there is different, but calm methods in all brands, it is not so difficult.

What I recommend is for find out the model of your motherboard and seek on the Internet the official manual; in this manual, get information on where are the pins that the user must use to reset the BIOS. In some cards mothers is difficult to get it and even he has no identification but nothing is impossible, so working colleague has said.

In addition, I commented that another way to reset the BIOS is removing the supply of energy from the source of power (power cable), uncover the case, and remove the battery from the motherboard for thirty seconds. Then, we put the battery back, connect the cable and it should already be reseteada. But the more practical: with the jumper that I have already commented on them.
