CMOS Checksum Invalid Error /CMOS Reset 502

Operating System: Microsoft Windows 10 (64-bit)

For a couple of months I have been having problems with my laptop's battery. It would suddenly discharge completely and my system would shut down. This got progressively worse until my battery would no longer charge. So I decided to remove the battery and everything runs like a dream now. Unfortunately, every time I reboot my laptop (cold reboot, not restart) I get the following error message: CMOS Checksum Invalid and CMOS Reset 502. My laptop then reboots again and it's fine.
Is this because I removed the battery since it was fine before? I've performed all diagnostics possible and everything is fine. My BIOS is up to date (had been prior to this problem) and my date and time are showing up correctly. This issue is very annoying and would like to know what's causing it. Also, I highly doubt it's my CMOS battery because my laptop is only a few months old. Thanks

Maybe you can try to replace a new CMOS battery.
