Question replacing CMOS battery on motherboard

[Turbonium]

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.

That's all there is to it. You will be fine.

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.

ground yourself before touching components

Can you swap the cells w/o completely removing power? As in PC in off state, but connected to AC.
