Right @Shaswati.

It makes hard disk failure.

@Mani.

You need to remove the CMOS battery for 10 seconds and then attach it.

Why COMS use in the computer?

@Tonny.

Mixed Metal Oxide Semiconductor(MMOS).

What is the full form of MMOS?

Simply remove the CMOS battery for a second then insert the CMOS battery again after this password and time are ready to reset again that is all.

When does cmos password appear?

I think we can remove the bios password by removing the jumper that is located on the motherboard.

How to remove the bios password?

Short for complementary metal oxide semiconductor. Pronounced see-moss, CMOS is a widely used type of semiconductor. CMOS semiconductors use both NMOS (negative polarity) and PMOS (positive polarity) circuits.

Since only one of the circuit types is on at any given time, CMOS chips require less power than chips using just one type of transistor.

This makes them particularly attractive for use in battery-powered devices, such as portable computers. Personal computers also contain a small amount of battery-powered CMOS memory to hold the date, time, and system setup parameters.
