Intro to Resetting the CMOS
Resetting the CMOS is an important step to take when troubleshooting your computer.
The easiest way to reset the CMOS is by turning off your power supply for about 10-15 minutes and then turning it back on.
If this does not work, try removing the battery from your motherboard for about 5-10 minutes before putting it back in.
And if neither of these steps works then follow the guide below.
How to reset CMOS on a PC
Resetting the CMOS on a PC is not as difficult as it may sound. It can be done with just two jumper cables and a power supply.
The first step to resetting the CMOS is to find where the battery for the motherboard’s clock is located, which will typically be close by or attached near other computer components.
You’ll need a small Phillips-head screwdriver in order to remove this battery from its housing.
Next, you’ll need to attach one of your jumper cables onto each of these pins (1 and 2) that are visible on either side of this battery’s connector; you should also make sure they’re oriented correctly: pin 1 goes into pin 1 while pin 2 goes into pin 2.
Lastly, you’ll need to attach the other end of your jumper cables onto any two metal pins on the power supply that are currently not in use.
Once you have everything set up, you can now plug in the power supply and turn on your PC.
After a few seconds, you should see the CMOS reset message appear onscreen, which will indicate that the process was successful.
You can then remove the jumper cables, put the battery back in its housing, and screw it into place.
As always, make sure to consult your PC’s motherboard manual if you’re not sure where these pins are located or which ones to use for resetting the CMOS.
And if you’re still having trouble, don’t hesitate to get in touch with a computer technician for assistance.

What is CMOS and why do you need to reset it?
CMOS is an acronym for Complementary Metal-Oxide Semiconductor.
It is a type of semiconductor that is used in integrated circuits.
CMOS chips are used in a variety of electronic devices, including computers.
The CMOS chip contains the BIOS settings for the computer.
These settings include the time, date, and other basic settings.
When the computer is turned on, the BIOS reads the information from the CMOS chip and sets up the system accordingly.
If something goes wrong with the BIOS settings, you may need to reset the CMOS.
This can be done by entering the CMOS setup utility and loading the default settings.
You can also reset the CMOS by removing the battery from the motherboard.
Either way, be sure to write down the current BIOS settings so you can restore them later.
Otherwise, you may have to set them up again from scratch.
How to identify if your PC needs a CMOS reset
The best way to identify if your PC needs a CMOS reset is by checking the system date and time. If they are not accurate, then your PC may need a CMOS reset.
Another way to check is to see if the CMOS battery is low. If the battery is low, it may not be providing enough power to the CMOS chip, which can cause problems with the BIOS settings.
The steps to take to reset the CMOS on your PC
There are a few steps that you need to take in order to reset the CMOS on your PC.
First, make sure that your PC is turned off. You can then unplug the power cord from your PC and remove the battery.
After a few minutes, you can put the battery back in and plug the power cord back in.
You can then turn on your PC and try resetting the CMOS again.
If that doesn’t work, you can try using the jumper pins to reset the CMOS.
What to do if the CMOS reset doesn’t work
If the CMOS reset doesn’t work, there may be a problem with the CMOS battery.
Open the computer case and locate the battery to replace the CMOS battery.
The CMOS battery is a small, silver-colored battery that is usually located near the CPU.
Unplug the old battery and replace it with a new one. Be sure to plug the new battery incorrectly.
How to clear CMOS jumper
Clearing the CMOS jumper is a way to reset your computer’s CMOS.
This will clear all of your BIOS settings and restore them to the default values.
To do this, you’ll need to locate the CMOS jumper on your motherboard.
The location of the CMOS jumper varies from motherboard to motherboard, so you’ll need to consult your motherboard’s manual for instructions on how to access it.
Once you’ve found it, use a small object like a pen or paper clip to short the two pins together.
Wait a few seconds, then release the jumper.
Your computer should restart and all of your BIOS settings will be restored to their default values.
If you’re having trouble accessing your BIOS, this can be a useful troubleshooting step.
How to clear CMOS without jumper
There are a few ways to clear CMOS without using the jumper.
One way is to use a screwdriver to short the two pins on the motherboard that clear CMOS.
Another way is to use a battery holder that has a button on it to clear CMOS.
Finally, you can use a USB drive to clear CMOS.
Each of these methods is described below.
Clear CMOS without Jumper
To clear CMOS without using the jumper, you will need a screwdriver and two pins.
The two pins can be any metal object, such as a paper clip. Locate the CMOS clear pins on the motherboard.
They are usually near the battery.
Use the screwdriver to short the two pins together.
This will clear CMOS and reset the BIOS settings.
Clear CMOS with Button
To clear CMOS with a button, you will need a battery holder and a button.
The battery holder can be found at most electronics stores.
The holder will have two metal pins that you will need to short together with the screwdriver.
The button is used to activate the holder.
Once the holder is activated, it will short the two pins and clear CMOS.
Clear CMOS with USB Drive
To clear CMOS with a USB drive, you will need a USB drive and a computer. The computer will need to be able to boot from the USB drive.
Download the CMOS reset utility from the motherboard manufacturer’s website. Burn the utility to a CD or copy it to the USB drive.
Reboot the computer and boot from the CD or USB drive. The utility will clear CMOS and reset the BIOS settings.
Each of these methods for clearing CMOS without using the jumper is simple and easy to use.
They are a great way to reset the BIOS settings if you are having trouble with your computer.
Frequently Asked Questions:
What is the CMOS?
As discussed above, the CMOS (complementary metal-oxide-semiconductor) is a chip that stores the BIOS settings for your computer.
When your computer starts up, the BIOS reads the information on the CMOS chip to determine how to boot your system.
If there are any errors on the CMOS chip, it can cause your computer to not start up correctly.
To reset the CMOS on your computer, you can either use a jumper or a software utility.
If you’re using a jumper, you’ll need to locate the jumper on your motherboard and jumper it closed for a few seconds.
If you’re using a software utility, you’ll need to download and run the utility on your computer.
Can you clear CMOS with a screwdriver?
Clearing CMOS with a screwdriver is a quick and easy way to reset the BIOS settings on your computer.
To do this, you will need a screwdriver and two metal pins.
Locate the CMOS clear pins on the motherboard and short them together with the screwdriver.
This will clear CMOS and reset the BIOS settings.
Do I need to unplug PC to reset the CMOS?
If you are experiencing problems with your PC, such as it not starting up correctly, you may need to reset the CMOS.
This can be done by unplugging the PC and removing the CMOS battery for a few minutes.
If you do not have the ability to unplug the PC, you can try using a jumper to short two pins on the motherboard.
