CMOS / Battery - Quick Questions

Recommended Posts

Posted · Original PosterOP

So I want to reset my CMOS and possibly replace the CMOS battery. My motherboard manual is a bit vague.

How do I safely remove the battery without damaging the motherboard? The manual doesn't say. And where would be a good place to buy a new one? Also, it says to use a metal screwdriver to touch the two pins for a few seconds. I assume I do this with the computer turned off, though I've heard people say you should be touching while you boot which I'd think that's something you shouldn't do. I think I touch the two pins indicated by the green arrows?

Push this pin back and the battery should pop out on its own.

Ok, thanks, I assumed it had something to do with that. What about clearing the CMOS?

"Clearing the CMOS" happens when the battery is removed and put back again after 10 seconds ;)

Yeah, I was wondering about that. It sounded like that may be the case from reading the manual, but it also sounded like you needed to put in a new battery to clear. The way It's worded in my manual is atrocious. But technically, you're also supposed to be able to touch 2 pins to clear the CMOS as well.  Or you put a cap/jumpers over the two pins. So I was wondering where the two pins were.

On some motherboards you can touch 2 pins and that'll clear CMOS. But that's mostly high-end motherboards that has that feature.

Yeah, well it says in my mobo manual that I can touch 2 pins. Do I need to wear an anti-static wrist wrap when I do this or touching my metal case good enough?

Yeah, never ever mess with CMOS-battery or its pins when the PC is turned on. Someone here on the forums did just that and their mobo was broken afterwards.

It's always recommended to wear a strap, but I never do it :D Im living on the edge.
