Can a laptop boot without CMOS?

I was under the impression that they couldn't. I tried resetting a BIOS password by removing and placing back the CMOS battery. Unfortunately, the piece of crap broke off at the tiniest touch. I was worried that I had broken the laptop, but then I turned it on and it booted up to the BIOS password anyway. So did that change or was I mistaken?

The way I understand it, the only thing the CMOS stores is changes to the BIOS. Without a CMOS battery the BIOS will go back to default settings every time the laptop is turned off.

Oh. Well that's not a big deal if it's the case (I also know it won't keep track of time). I was worried maybe I had broken it.

What exactly broke off? The thing that holds the motherboard battery?

Generally to reset a laptop BIOS you have to remove the BIOS battery (if it's accessible), remove the laptop's main battery, and unplug it from the wall.

Yup. It was literally held on by a little plastic piece and a drop of solder. I gently pushed on the battery a bit and it snapped off.

Ah yeah, then your BIOS is just going to be reset every time you reboot.
