CMOS time / Battery Fail RESOLVED for me.

Specs: Windows 10
I had a similar issue with an ASUS board from a system I built nearly 4 years ago. I performed all the checks mentioned but still the same issue where the clock was resetting when the PC was powered off at the wall.

I removed the motherboard and voltage checked the CMOS battery contacts at the BACK of the board with the battery in. I found that I had to press really hard on the solder to get a reading. Upon closer inspection there was a dry solder joint on the positive connection.

I then removed the battery plus RAM and resoldered both joints. I then retested the volage with the battery in and I got a steady reading of 3V. Perfect.

I rebuilt the system and tested it. Working fine now.
