Hello,
A few days ago, I noticed powering on my computer showed MSI splash
screen (had this disabled) and then it went to BIOS screen to say "CMOS
Checksum error. Defaults loaded."
I was hoping it was a hiccup. I powered off the machine off and on to
see if it remembers my settings, nope. I had to reconfigure it
(annoying). The next day, it happened again. I usually turn off my
machine (including its SeaSonic 650 watts PSU) when I go out to work
(11-12 hours long) or gone for a long time when the machine is unused.
I did try turning off my machine without turning off the PSU for about
five minutes. Turning on did not show resetted CMOS. I have NOT tried
leaving my PSU on when the computer is off. I am not sure if that is
going to keep my CMOS settings intact or charge the battery. I usually
like to turn everything off completely (no lights and stuff) to avoid
those small energy usages.
Is the motherboard's battery is totally dead or is it just bad luck? I
only had this MSI K8N NEO4-F (MS-7125; PCB v3.0) motherboard (NVIDIA
nForce4) motherboard before Christmas 2006! Aren't CMOS batteries
supposed to last for years?
Thank you in advance.

Yes, batteroes should last for years, but wouldn't it make sense at this
point to simply take out the battery and test it with a VOM to see what its
got left before arguing that it's the battery in the first place? It should
read 3V if it's in good shape.

Is there a way to check via the computer like those hardware sensors? Or
do I need to verify it via a physical battery reader device (need to get
one)?

Also, I forgot to mention that I am already using the latest BIOS from MSI
since I ever got this motherboard.

Regardless of what the software is reporting it would be conclusive to
follow earlier advice. The software is reporting the battery voltage while
the computer is on and there is some charging going on of the battery in the
first place. Being resistant to following some very simple recommendations
will not solve your problem and eliminate knowing if the battery is your
problem.

There is no charging going on, on the battery. Batteries have a diode in
the path, which allows only discharging, no recharging. This 440BX reference
schematic from Intel, shows an example of the diode ORing used in the circuit.
Try PDF page 18 here, lower left corner. The BAR43 Schottky is selected for a
low forward voltage drop, which gets the best usage from the available battery
voltage. Current flows only one way through the BAR43..
