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?
