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:
- 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.
- Check for hardware issues: Check the motherboard for any visible physical damage or loose connections that may be causing the issue.
- 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.
- 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.
