Why Does My Motherboard Have a Battery?
In older desktop and laptop computers, the motherboard has a built-in battery that can be charged. LGA 1150 Processors You can still use your computer when it’s plugged into the battery on the motherboard. It doesn’t, however, give it power.
It is a little battery (also known as the “CMOS”) but it is only activated when the computer is unplugged. Computers work even when they are not in use.
There is a battery on the motherboard. So, what’s the deal with this? How long can a CMOS camera run on a single charge? We’re going to find out.

Why Do You Need a Battery for Your Motherboard?
It doesn’t make sense to put batteries in motherboards if so many computers already store their BIOS settings in non-volatile memory. A simple fact: RTCs can still be found on most motherboards these days (RTC).
If you turn the computer on or off, the battery is always going to be plugged in. The real-time clock is a kind of quartz watch. It resembles an antique wristwatch in appearance.
As long as the computer is not being used, the timer is still ticking away. As soon as you start your computer, it will always know what time it is thanks to this.
Is Your Motherboard’s Battery Doing the Job?
People know that batteries don’t last forever, so this should come as no surprise to anyone. CMOS batteries can last for up to ten years before they need to be replaced. If you use your computer’s CMOS battery a lot, it will last a long time. However, if a computer is turned off a lot, its battery life will be much shorter. This is because the battery is being used more often.
Older computers that keep their BIOS settings in CMOS will show error messages like ACPI BIOS Error, CMOS Checksum Error, New CPU Installed if the battery that keeps the BIOS settings alive dies.
This last one is the hardest to understand at first, but it’s simple to figure out. It’s impossible for the BIOS to remember that the CPU has already been installed if the motherboard doesn’t have a battery. The computer thinks it’s brand new every time you start it up.
Computers with non-volatile memory that stores BIOS settings may startup, but the computer may not be able to keep track of time when it’s turned off on a newer computer. It’s worth the time and money to fix this because it can cause problems with connectivity and getting new software and apps.
Instructions for Replacing the CMOS Battery on a Motherboard:
You will need to change the battery on the motherboard, which is called the CMOS. It is common for calculators, wristwatches, and other small electronic gadgets to have a CR2032 battery in them.
Make sure you start by shutting down your computer, unplugging your power cord, and taking the battery out of your computer if you’re using one. You should be aware of static electricity when you open your computer. You should also follow basic computer maintenance rules.
Some computers connect the battery to the motherboard by soldering it. A total motherboard replacement or a factory repair will have to be done in order to fix this.
Troubleshoot PC Problems by Removing the CMOS Battery:
An old computer’s “pulling” process, when the CMOS battery is removed and then put back in, can also be used to figure out what’s wrong with it.
For example, taking out and replacing the CMOS battery can make a computer’s BIOS password go away. However, you will also lose all other BIOS settings if you do this.
Not all passwords that are kept in non-volatile memory will work even if the power goes out. The motherboard has a jumper that might let you reset the password. If the computer is starting up, you can also change the BIOS settings from inside the BIOS. To find it, clear the CMOS or reset the device to its factory settings.
Because of this, your motherboard has a battery life!
The reason your motherboard has a battery is that it needs to be charged.
On older computers, the CMOS battery saves the BIOS settings so that they don’t get lost.
The CMOS battery runs the clock on more modern PCs.
Your motherboard’s CR2032 battery can be simply replaced. In some cases, the battery is permanently attached to the motherboard, so you can’t remove it. Whatever the case may be, you should be able to locate a replacement CR2032 battery easily enough.
There are a lot of different batteries out there, but the 18650 battery is one that you might not have heard of before.
