The CMOS (Complementary Metal-Oxide-Semiconductor) battery is a small battery that provides power to the motherboard’s CMOS chip. This chip stores your computer’s hardware settings, including the date and time, boot order, and other important configuration settings. Without the CMOS battery, your computer won’t be able to remember any of these settings, causing errors when you try to boot it up.
When the CMOS battery dies or is low on power, your computer will display an error message telling you to press F1 to run the setup. Pressing F1 will take you to the BIOS setup screen, where you can configure your computer’s hardware settings.

- Insert the new CMOS battery into the socket, making sure it is firmly seated and oriented correctly.
- Close the computer case and plug in the power source. Turn on the computer and enter the BIOS settings to ensure the new CMOS battery is recognized and functioning properly.
If you see the “press F1 to run setup” error message, don’t panic. It’s a common problem that can be easily fixed by replacing the CMOS battery. With a new battery installed, your computer will be able to remember its hardware settings and boot up normally.
