What is the purpose of the motherboard battery?

Question

Hello, this is what the motherboard battery is for because I am being asked to remove it in order to enter my PC without a password? Is that true?? thank you

Hi there!
On the motherboard is the ROM. A read-only memory that cannot be changed. For quite some time now, we've also been using CMOS: a volatile memory that contains basic and essential information.

If the CMOS is no longer powered, it empties. The battery allows it to be powered when the PC is off.

If you want to get rid of your password… are you talking about the BIOS password? Or the Vista password?

I don't know, but I know that the battery is used to save the time on your PC. For example, when you turn off your computer so that the time continues to pass and doesn't reset to 0:00 when you turn it back on.

Well, I'm not an expert, but as soon as I turn on my PC, I'm asked for a password before Windows.

So you're advising me not to remove it?? That if we remove it, I'll still have my password?

Hello,

back in the day, the name "cmos" used to be called "EPROM" with a rectangular shape.
the battery keeps the time, date, and other little info from the motherboard.
if you want to reset the BIOS, make a backup of the settings first, either using software or by utilizing the utility available in the BIOS found on most motherboards.

see you!
