Thread: CMOS Checksum Error Solution

From last 2-3 days my PC started displaying "CMOS checksum error" message every time the PC is started. I think it is a problem with CMOS Battery. Let me know if any one knows how to fix it. Any help would be highly appreciated. Thank you.

Solving this problem is easy. Here are the steps to follow.

• Open PC cabinet.

• On the mother board find the lithium battery cell holder.

• Gently press the battery holder to free the battery from its place

• Take the model number on it.

• Buy a new battery of the same model number.

• Placed it in its original position.

• Ensure that the new battery is firmly sitting on its holder.

• Set once all your default BIOS settings and save and exit them.
