Tip: For some computers, you should disconnect the cable, remove the drive, or remove other parts of the computer to physically access the CMOS battery. Step 1: Open the computer case and find the CMOS battery connected to the computer motherboard. If the battery is a few years old, it's time to replace it with a new one. One of the main causes of the CMOS checksum error is CMOS batteries. This error can also be caused by incorrect BIOS settings, which could be related to new devices that you have added. However, two different causes can still be identified, and all troubleshooting methods are based on them.ĬMOS batteries don't last a lifetime, and after a few years, they don't provide enough voltage to boot the BIOS, and the problem arises.
