How i change its cmos - Computers & Internet

Error code 87 typically indicates an invalid parameter or incorrect command-line argument in the context of Windows API calls. However, the context you have provided is related to changing the CMOS settings, which is related to the BIOS (Basic Input/Output System) and not to the Windows API.
If you are unable to change the CMOS settings, it may be due to several reasons such as the CMOS battery being low or dead, a hardware issue with the motherboard, or the settings being locked by the manufacturer or system administrator.
To troubleshoot this issue, you can try the following steps:

1. Replace the CMOS battery: A low or dead CMOS battery can cause issues with changing the CMOS settings. Try replacing the battery with a new one.
2. Check for hardware issues: Check the motherboard for any visible physical damage or loose connections that may be causing the issue.
3. Clear the CMOS memory: Try clearing the CMOS memory by removing the battery and leaving it out for a few minutes, then replacing it and restarting the system.
4. Contact the manufacturer or system administrator: If none of the above steps work, it may be that the settings are locked by the manufacturer or system administrator. In this case, you will need to contact them for assistance.

It's important to note that changing the CMOS settings can be risky and may cause stability issues with your system. So, make sure you know what you're doing and have a good reason for changing the settings before attempting to do so.

Hi there,

When starting your PC, the following error message is displayed:

CMOS wrong
CMOS MEMORY size WRONG
CMOS Checksum Bad
CMOS checksum error defaults loaded
Warning! CPU has been changed please re-enter cpu settings in the cmos setup and remember to save before quit!
You are prompted to:

Press F1 to resume
Press F2 to load default values and continue


This is due to the fact that the CMOS, which contain data related to the BIOS, has been reinitialized and that your PC has been reset to factory settings.

Solutions:

Reinitializing the BIOS

• • Before making any costly maintenance try to reinitialized the BIOS.
• Change BIOS battery
  • If the problem persist this may be due to the fact that the battery powering the CMOS (when the computer is shut down allows the CMOS to store information), is depleted.
  • The CMOS battery is a small pin found on the mother board, you can refer to the manual provided with your motherboard to change it or have the nearby computer technician change it for you if you don't want to risk any damage.
  • More information with: Replacing the battery of your motherboard (CMOS battery)

Please change Your CMOS battery into new because I think that is the problem and after you change
your CMOS battery it will be fine and your computer will work it well.

Just change your CMOS battery with a new one and after that goto the bios settings and update the time and dare.
After that just save the settings and then check that the warning message is coming or not.

If its coming then it means you need to change the CMOS jumper settings.
