MSI K8N NEO4-F motherboard, CMOS battery, and recharge...

    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.

    Sounds like the battery. They can fail on their own, or can be drained
    by a short such as a misaligned mounting stud or the back of the case.
