How to Fix CMOS Checksum Error in Windows 10

Restart your computer. Normal reactivation usually generates a new checksum and corrects the error.
Download and view the BIOS update. Download the redesign from the motherboard manufacturer’s website.
Definitely reset bios.
Replace CMOS battery.
Contact a technician or computer cleaning specialist.


If the problem persists because you turned off your computer, your CMOS battery is often dead or defective. Try leaving the computer on for a few days before replacing the CMOS battery. If sometimes, leave the computer on normally, most of the battery will be charged.

How do you reset the CMOS?

Turn off your computer.
Unplug the computer work station from the electrical outlet.
Press the button several times to clear almost all capacitors.
Locate the motherboard CMOS battery on the motherboard.
Carefully remove the CMOS electronics.
Wait a few minutes, change the CMOS battery a little.

The CMOS checksum may not display correctly when starting the computer. internet marketers may encounter a CMOS checksum error when there is a conflict between CMOS (Complementary Oxide Semiconductor) metal data and BIOS (Basic Input/Output System) data.

Every time you turn off your PC, CMOS writes a number, and ifCMOS values ​​must not match the BIOS descriptors on startup, Windows 10 may experience a good CMOS checksum error. If the error is related to your current hardware, then no solution to fix this error related to your computer will definitely help you. However, trying some important fixes helped a lot to fix the Checksum cmos Bad error in Windows 10.

What Causes CMOS Checksum Error In Windows 10?

How do I fix CMOS checksum error Windows 10?

restart some computer.
Replace battery.
repair the CMOS battery terminals.
Reset BIOS.
Update BIOS.
Change the motherboard frequently.

The main cause of the CMOS checksum error message is a problem with the CMOS. Either the CMOS is damaged or the CMOS battery is not working. Some other reasons:-

  • Legacy BIOS
  • Splash
  • Sudden power failure caused PC to shutdown
  • Eating problems
  • BIOS virus
  • Infected motherboard damage
  • If your new motherboard or optional MOX battery is damaged, you need to replace it. If performance has problems with cmos, you may encounter ten Windows sync errors. However, other reasons are usually possibleto change by only making changes to the computer.

    9, Solutions To Fix CMOS Checksum Error

    You may need a bit of technical flair to try out some of our own solutions below, especially the hardware BIOS. However, you can always effortlessly try other solutions to see if they work for you.

    1. You Can Restart Your Computer

    Sometimes a recent restart of the computer resolves a CMOS checksum error. Now, if the problem is just a power surge or a bad boot, an effective reboot can help. Since you may not be able to access the system, of course, you will have to force a reboot.

    Can a dead CMOS battery stop a computer from booting?

    A CMOS error will prevent the PC from booting normally. Essentially, the PC boots up and stops at a BIOS screen that prompts you to press F1, hto continue booting the operating system. Due to a defective CMOS battery, the product cannot remember the current date/time to return to it each time the mechanism is started without a battery.

    Press and hold the physical power button on your laptop’s processor until the system shuts down. Then you have to press the Power button as soon as you turn on the computer. 22429%22%3E%3C/svg%3E”>

    Press the physical power button

    Check if a check error appears when summing, I say OS or boot number.

    2. Press Function Keys

    If the audience is still getting a CMOS checksum error when starting the computer, you can try pressing the F1 key to get good performance. The F1 key continues the boot process. If the f1 key does not solve the problem, you can also try the F2 key. Chances are this solution will help you fix the cmos checksum error, but less worth a try.

    3. Perform Autorun

    You can run Startup Repair to resolve CMOS checksum errors. In order to run this repair, you need to join the Windows 10 advanced settings run.

    You can enter additional options until the Windows environment is restored. Also, outside of the Windows Recovery Environment, you can access advanced troubleshooting options.

    After you are done with the options, click “Advanced” in the recovery menu, “Start” to start the process.

    Start recovery

    You can follow the books behind on the screen to complete the repairs. In many cases, if there is no problem with the hardware, the particular download will fix the Von error on its own.

    4. Outdated BIOS

    A BIOS update can also cause a lot of problems and errors on your computer. You can update the BIOS manually by downloading the current specific BIOS version from the specific manufacturer’s website. However, they make sure you deliver them so carefully. In case of errors, movements in the bios type, the PC may be damaged beyond repair. updating An incorrect BIOS can also cause many other problems with your PC.

    Each manufacturer has different ways to install them and update the BIOS. Therefore, you can refer to the user manual that came with your PC or visit the manufacturer’s web blog for detailed instructions on updating the BIOS.

    5. Check For Hardware Errors

    Check for damage

    Your hardware may experience a checksum error, be it cmos, a hardware failure, or a corruption in your computer’s factory. For example, if the computer motherboard is dented, the CMOS battery will not work, resulting in corrupted CMOS data.

    You can take your computer apart to check that the circuits, motherboard and other products are working properly and that they do not show signs of physical damage. If you haven’t already done so, you can contact One Aid Market experts. Sometimes disassembling a laptop or processor incorrectly can cause more and more problems, so make sure your company does it carefully and correctly.

    If almost all hardware faults are present, you may need to replace or even repair the component. You can check with the motherboard manufacturer if they can replace a damaged component.

    6. Reset BIOS

    Many users have fixed a bug that caused the BIOS to reset an incorrect CMOS checksum. This solution may be helpful if you have recently contributedOther BIOS changes AND that didn’t work. However, a full BIOS reset will not delete data files, folders, and application settings from your computer.

    What is CMOS failure?

    a manifestation of a CMOS battery failure – an absolutely incorrect or slow system date and a certain time in the BIOS, loss of BIOS settings when the clock is turned off, the computer is stopped, error content, etc. If the CMOS battery is dead, your current BIOS settings will be lost when you turn off your computer.

    Step 1. Go to BIOS setup on your computer. Now you can check the manufacturer’s manual on how to enter the bios plan of the car, it is different for each model, then for each manufacturer.2:

    Step. enable the “Load settings” option in the BIOS menu is required. In the vast majority of cases, you’ll find a “Restore Settings” button at the bottom of the screen. Ezah=”250″

    Several steps: when prompted to confirm, say “Load BIOS default settings”, click “Yes”, otherwise click “OK”. The confirmation signal may vary system from system to system.

    Step 4: Save your changes and exit the BIOS screen. This will reset the main BIOS to correct BIOS settings.

    Now restart your normal computer and check if your shoes are working.

    7. Attach The CMOS Clips

    If the CMOS battery is not properly connected to the system Removable board, a CMOS error may occur. Do you need to check the connections of the negative and positive poles of the battery correctly and that there are no other loose connections?< /p>

    You may need to access the motherboard from your PC. Again, with the help of an expert, you can enable the key field to access the component.

    8. Replace The CMOS Battery.

    Replace the CMOS battery

    Even after checking for a slack connection to the cover, if the checksum error cannot be resolved and you are still getting failed reboots, you may have a CMOS battery problem. It can detect a battery drain issue. Anyone can replace the CMOS battery on their own with a new one, if you have a deep knowledge of computer hardware. Eza=”250″

    In many cases, the CMOS battery will need to be replaced after five years. So if it’s been 8 years since you changed your battery, replace it now to find workarounds for common ones. errors.
