The simplest way to check the CMOS battery's health is to use your computer itself as the test device. The battery's whole job is to back up the BIOS settings when the computer loses power, so if you deliberately cut power to your computer, you'll know if it's doing that job. It'...
Now, the fastest way to test your CMOS battery is by checking its voltage with a digitalmultimeter. To do that, though, you'd have to open your PC's case and remove the battery, and you'd need to own a digital multimeter. There's a simpler (if less immediate) method we recommend:...
If that happens, the CMOS memory chip can no longer hold your BIOS settings between power cycles, resulting in a full BIOS reset. Gross. To counteract this, it’s helpful to check the CMOS battery periodically. And the good news is you don’t need highly specialized equipment to do it....

Now, follow the steps below to check if the CMOS battery is the cause for your PC to keep booting into BIOS or not. Take out theCMOS batteryfor a minute or two and then insert it again properly. Start your PCand see if it still loads to BIOS or not. ...
CMOS Checksum Error CMOS Battery Failure System battery voltage is low If your PC frequently displays an error message about the BIOS settings being cleared, there's a high chance your CMOS battery has been depleted. CMOS coin cells typically have a lifespan of three to five years, so even ...
CMOS stands for “Complementary Metal Oxide Semiconductor.” The CMOS battery powers the BIOS firmware in your laptop [2]. BIOS needs to remain operational even when your computer isn’t plugged into a power source. That’s where the battery comes in. When your computer gets unplugged, ...
