FUNDAMENTALS OF COMPUTER

Detailed explanation-1: -When your computer gets unplugged, BIOS relies on the CMOS battery for power. You’ll find CMOS batteries in both laptops and desktop PCs, but it’s used more frequently in a laptop. That’s because laptops are usually unplugged for a longer amount of time than desktop PCs.

Detailed explanation-2: -CMOS battery The memory battery (aka motherboard, CMOS, real-time clock (RTC), clock battery) is generally a CR2032 lithium coin cell. This cell battery has an estimated life of 3 years when power supply unit (PSU) is unplugged or when the PSU power switch is turned off.

Detailed explanation-3: -The CMOS battery is also responsible for keeping track of the computer’s time and date systems. If you have a dying CMOS battery your computer will have problems booting up. You might also notice other changes like disappearing drivers and incorrect date and time.

Detailed explanation-4: -One of the key components in your computer is the CMOS battery. This little battery helps keep your computer running by providing power to the CMOS (complementary metal-oxide-semiconductor) chip.

Detailed explanation-5: -CMOS battery The CMOS battery is a small round battery found on the motherboard of every computer. It provides power to the complementary metal oxide semiconductor (CMOS) chip. The CMOS chip stores BIOS information and computer settings, even when powered down.
