When a PC shuts down, the CMOS (Complementary Metal Oxide Semiconductor) battery powers the CMOS chip. The BIOS configuration and data are stored on this chip. Thus, we can take out the CMOS battery in the event that we ever need to reset the BIOS.
The CMOS battery is easy to remove. Finding them, though, might be challenging, particularly for inexperienced PC builders.
We're going to demonstrate how to recognise and get rid of them in this article.Let's examine the necessity of removing a CMOS battery first, though.
What Justifies the Removal of the CMOS Battery?
All BIOS settings can be restored to their original state by removing the CMOS battery. Therefore, we can attempt to remove the CMOS battery to resolve the problem if we have a PC that does not boot up because of a BIOS error.
The CMOS battery is dead, which is another reason we must remove it. If your CMOS battery is dead, the computer's BIOS will keep resetting each time it is turned off.
How Can the CMOS Battery Be Removed?
A little metallic lever can be pressed to effortlessly remove the CMOS battery, causing it to pop out. But because manufacturers vary in where they put the CMOS, novice PC builders can have problems locating it.
We have included the following steps to make the process of taking out the CMOS battery as easy as possible. Please take each step in turn.
Take these actions to discharge the motherboard before proceeding.
- After shutting down the computer, disconnect the cord from the wall outlet.
- For any capacitors on your motherboard that may be inoperative, press the power button four or five times.
