HP Laptop in a boot loop - https://www.hp.com/go/500bioserror

Hi, My HP Laptop is in a endless boot loop. All the of scanning for hardware, software, memory, etc, errors have all come back as good. Here is the error I receive: "The CMOS checksum is invalid. The CMOS will reset to the default configuration, and the computer will restart. Afterwards, please check the BIOS setup options to see if they change. CMOS Reset (502); Enter - Restart the computer. For more information, please visit: http://www.hp.com/go/500bioserror"

When I press enter, my laptop just gets stuck with the HP icon displaying and spinning. When I try going to the link for more information. The link is invalid and does not work.

Please help. Thanks

I have done some further troubleshooting. I'm thinking it may be the CMOS battery. Does anyone have any steps that can help me locate and replace the CMOS battery? Thanks
