I figure it's as straightforward as:
  • disconnect computer from power source (turning off the power via the PSU switch should suffice, right?)
  • swap out the CMOS battery
  • boot up computer and reconfigure BIOS settings
Seems silly to ask this, but I'm just making sure.

Being the renegade I am, I swap batteries before they die, leave computer running, do not reconfig bios settings. Helps to be really careful, often I have to use needle nose pliers or forceps to get access to the battery release tab without moving other things out of the way... don't want to short anything out, a strong flashlight helps.

Recently I happened upon a rarity, a CR2032 that LEAKED. Fortunately it only made a mess on itself, very small leak but is still the first I've seen of these leaking, was a major brand Sony cell too.
