Do you password protect your Bios?

[MrD.]

So, would removing the battery and putting it back in be fine, or would you need to replace the battery with a different one? Or, can you remove the battery and start your PC that way? Or does it need the battery to start?

Yes, no, yes, no.

You would probably want to replace the battery if it was dead.

No, your PC doesn't need one, but it would mean that you would have to reset all your BIOS information to the correct details every time you used your PC after disconnecting it from the mains.
