Sorry if this is the wrong place to post this, redirects welcome.

I've got an old MSI Z97 mobo. Not surprised the CMOS battery died, but I replaced it and it doesn't seem to have fixed anything. Any time the board loses power the startup settings still reset and I have to use the physical keyboard to reconfigure it; not conducive to controlling it remotely as I'd prefer. Any ideas?

welp, replacing the replacement seems to have done the trick!
the og battery i replaced is long gone, but this is the replacement i put in like a month ago

the empty slot

and now a NEW replacement, i never would have thought to do it again.

i put the sony battery into a different mobo and it seems to work... i swear i had it pushed all the way in, idk why it wasn't working. thanks for the help though!

That motherboard has a CMOS reset jumper next to the CMOS battery--two metal pins sticking up labelled "JBAT1". Connecting the pins with a jumper cover tells the system to clear the CMOS memory on boot. In normal operation the pins should not be connected.
