Keyboard Failure On Boot, Clearing CMOS Is A Possible Panacea

I got a scare today!  My computer’s motherboard can sometimes be very unfriendly.  What had happened was that I turned off my computer while the Mobo was trying to boot up the BIOS, and this was when I got the scare as the Mobo would spit out keyboard failure error on the next boot up.  I’m telling you this, if you never have had experience this with your computer, you would not know the panic and frustration of this scare!  Keyboard failure error on boot would not allow you to use your keyboard at all to bypass the black error screen stage even though the screen would encourage you to press F1 or F2 to get pass it.  Trust me, I had tried to press just about anything on the keyboard to have a try at getting pass this scary black screen of death, but nothing would work!

Naturally, I went into instinctive mode by switching out the USB port for the keyboard’s USB connector, but this was a futile effort.  I watched a YouTube video that suggested of pressing F1 really fast till at certain point and then holding down F1 till certain point on boot up to get pass the black screen of death, but this method just did not do it for me.

Consequentially, I got physical with the Mobo by accessing it physically!  Don’t worry, the Mobo is fine, because I did not punch or kick it.  Anyhow,  what I did was clearing CMOS using the jumper on the Mobo.  I don’t know about your Mobo, but mine came with 2 jumpers.  The first jumper got 2 slots to slip onto 2 pins of the first three pins jumper group, and the second jumper got 2 slots also to slip onto the 2 pins of the last three pins jumper group.  In my case, I had to remove the first jumper physically from the first three pins group and slip the jumper onto the first and second pins of the first three pins group.  Right after, I repositioned the graphics card and what not so the computer would run normally as before, I powered my computer back on.  Of course, nothing would happen, because the jumper wasn’t in the right position for anything to work, and so I had to remove and reposition the jumper to the second and third pins of the first three pins jumper group.  Once again, the pain of reaching the jumper slots meant I had to remove the graphics card from its slot, but the inconvenience was unavoidable.  Unfortunately, even after clearing the CMOS with the jumper, my Mobo was still spitting out the keyboard failure error on boot.  Back to square one!

Onto the second method of clearing CMOS, I removed the CMOS battery from the Mobo for at least thirty minutes.  Afterward, I repositioned the CMOS battery and rebooted the computer.  Unfortunately, even this would not get me pass the black screen of death!  Naturally, I thought that my computer was done for!

Fortunately, after the second try of clearing the CMOS with the motherboard’s first three pins jumper/group, the computer was finally booted pass the black screen of death.  Windows is now booting up just fine as the result, and I’m able to use the keyboard just fine.  Everything else works just fine also!  The scare is finally over!

In summary, clearing the CMOS should be your last resort to fix most BIOS related failure errors on boot!  Of course, even clearing the CMOS sometimes won’t get your computer going again, because your computer’s motherboard might be done for at this stage for whatever reasons!  Another possibility is that the CMOS battery could have died on you and need a replacement before clearing the CMOS would actually work as intended!  In my scenario, clearing the CMOS with a motherboard’s jumper is the panacea to the health of my computer.  By the way, here is my warning, don’t get physical with your computer’s motherboard unless you know what you are doing!  Warning is here for a reason… just in case you would blame me for your motherboard screw up when you find yourself in a similar situation as mine.  Anyhow, if you ever find yourself in this similar situation, I think clearing the CMOS will get your computer going again!

Sometimes, when you visit YouTube and right away a video begs for your attention, and the one which I’m going to share with you within this blog post is exactly that.  The title for the video is a bit misleading, because you won’t be able to make a motherboard even if you actually watch the whole video.  Nonetheless, the title goes “How to make a Motherboard – A GIGABYTE Factory Tour Video.”  I must warn you though, the speaker for the video had a strong accent, and so it was hard for me to actually understand him as I tried to watch the video.  Luckily, the video itself is well done as it shows the motherboards go through orderly steps of being manufactured (i.e., how the motherboards are pieced together by machines and humans).  Even though the video was uploaded around two years ago, it was quite interesting for me (and probably you too) to be able to see how the motherboards were assembled.  Today motherboards are probably being assembled in similar manners!  Enough with the rant from me, check out the video right after the break and enjoy!
