When you change the BIOS battery, it may be worth doing a BIOS reset,
and then customise the settings you want. For settings you're sure
aren't doing what they should be, sometimes toggling them off and on
again kicks them into submission. BIOSs (I'm including UEFI in that)
often go haywire with flat batteries. I've found that sometimes the
settings don't reflect what the BIOS says they're set to.
On any PC I have, the /what to do after the power comes back on/ option
is purely down to the BIOS settings.
I remember one ancient PC with a firmware error, toggling some BIOS
settings corrupted other ones.
A common memory failure mode is a value being set at one memory cell (bit)
location also changes the value set previously at an adjacent location. Resetting
the BIOS may fix such errors.
