the CMOS Checksum Bad Error, hence they can be handled effectively. The Error Explained A checksum is computed as an error detecting code to guard the BIOS settings stored in the CMOS memory. The CMOS Checksum Bad Error is an error that occurs when the CMOS values turn out to be incorrect. The CMOS memory stores a specific value normally to guard the BIOS software. Each time the computer is booted, this value, which is a number is checked against the stored value in the CMOS memory. If these two values are different, it causes a CMOS Checksum error message. If these values are the same, the computer boots normally. Each computer usually deals with the CMOS Checksum Bad Error differently. Some computers warn the user and continue to boot up using settings in the CMOS, while other computers might warn the user and use the default settings in the BIOS as the correct settings and carry on with a normal boot or reboot. Usually, the strategy the computer employs is stated in the error message. Causes of CMOS Checksum Bad Error There are usually three main reasons that a CMOS Checksum Bad Error occurs. They include: CMOS Battery may not be functioning properly. The battery life may have expired. The user or a virus may have updated the BIOS. The computer may not have been shut down properly e.g. shutting off the computer's main power without first shutting down the computer (MS Windows requires the computer to be shut down before the power is shut off).

CMOS Battery May Not be Functioning Properly If the user suspects that the CMOS battery is not functioning properly, he/she can easily change it. Before changing the battery, reboot the computer to make sure that the error still exists. If it does, go into the CMOS and write down all of the settings. If all the settings a
