The CMOS settings on my motherboard are going away, while the date and time stays. I have attached an image that show the relevant message at the bottom:
Press enter Setup to recover BIOS Setting
Press F1 to run Setup
Press F2 to load default values and continue


This happens after I disconnected all power to the computer including UPS turned off. then turning the UPS back on and starting the system.

What I've tried:
1. Disconnected all peripherals except KB & mouse with monitor.
2. Used a battery I had recently purchased for another motherboard ( as good as new)
3. Disconnected the Hard Drive and tried booting - same result.
4. Since Hard Drive disconnection has no effect, windows isn't interfering.

You can try to press F2 (load default values) and save them once. The only other reason for an automatic beside the battery is a non-working setup (overclocking for example). Loading the defaults and starting from there would correct that.

@NEmpire95 - Its the latest version, I wonder If downgrading might help.

@weberdarren97 - Its about 6 years old. Whats a CMOS RAM, is it something like the NVRAM ?

I can see the date/time intact in the BIOS though the settings are lost. I usually disable the floppy but after the reset the BIOS enables the device.

I've ordered a battery from Ebay, and it'll take some time to arrive. Is there any other fix I could try out in the interim ?

I will do that until the new battery arrives, though I guess I will have to do that everytime I boot the PC from a complete power-down ( including UPS off)
