CMOS is the place where the computer stores settings related to hardware parameters like RAM, CPU buses, or the computer's clock. Thanks to CMOS, when you turn on your computer, it retrieves the stored settings and helps the computer start up. However, sometimes the computer displays a message on the screen like this:
Above, you can see the line 'CMOS checksum error – Defaults loaded' and below it, instructions 'Press F1 to continue, DEL to enter SETUP.'
Fixing the 'CMOS Checksum Error'
In this scenario, the issue arises from your CMOS battery running low, causing the CMOS to lose its effectiveness. Insufficient power for the BIOS to store hardware settings leads to the computer's confusion about how to boot. Additionally, a depleted CMOS battery can result in incorrect timekeeping on the computer clock.
As shown in the image, this is the CMOS battery. Your task now is to locate a computer store and purchase a new CMOS battery. Begin by disconnecting the power cable from the computer, then remove the case and replace the old battery with a new one before restarting.
By following the steps outlined above, you can see that resolving the CMOS error preventing Windows access is quite straightforward. This allows you to use your computer efficiently without wasting time on adjustments such as fixing the time caused by the 'CMOS Checksum Error' on the system.
