Most of us are familiar with all the programs on our computers or laptops. Well, the ones we need mainly. Other than that, they serve some kind of purpose that we don’t know.
So if someday you wake up and turn on the power of your PC and it’s not turning on, it’s not a good sign. Because you are not sure what you have done wrong. You just played your favorite GTA V missions the other night or finished making your presentation and everything was fine.
And the power cord is on, everything is fine, just the PC isnt turning on. Even if does somehow, the dates are like in the BC era.
The reason behind that is most of the time your CMOS battery is out. Now what does a CMOS battery do, and what is it anyway?
We are here to discuss that in this article.
What Does a CMOS Battery Do and How to Change Them
CMOS batteries are one of the elements that keep your computer’s memory and settings alive. Without it, your machine will run fine, but not as smooth as you once used. Hardware like the sound card, graphics card, keyboards, and mouse will start acting up. Worse, the computer will not be able to recognize them at all. So it is better to check on the beeping noise coming from your motherboard and change the battery.
