What is CMOS checksum error defaults loaded?

CMOS checksum error – Defaults loaded Checksum of CMOS is incorrect, so the system loads the default equipment configuration. A checksum error may indicate that CMOS has become corrupt. This error may have been caused by a weak battery. Check the battery and replace if necessary.

How do I fix checksum error on my computer?

Bad or old CMOS battery Reboot the computer. If the error still occurs after rebooting the computer, enter CMOS setup and check all values. Also, verify the date and time are correct. Once everything is verified and changed, make sure you save settings and then exit the CMOS setup.

What is a bad checksum error?

A bad checksum error results when the file fails this check, meaning that some part of the data no longer corresponds to the original. If your data fails a checksum verification, it usually means that you need to replace it from a backup or otherwise reconstruct the affected file.

If the error no longer appears, wait until Windows opens and set the date and time to current settings. If the error still appears, the default BIOS information has become corrupted.

What happens if CMOS battery failed?
