Do desktops use batteries?
All personal computers have a small battery on the motherboard that provides power to the Complementary Metal Oxide Semiconductor (CMOS) chip, hence the name CMOS battery. The chip has the information about all the system’s configuration, such as the hard disk, date and time, etc.
Where is the battery in a desktop PC?
PCs have a battery on the motherboard that provides the Complementary Metal-Oxide Semiconductor with a minimal amount of power, even when unplugged. This CMOS battery lets the system clock keep running even when the computer doesn’t have power, and allows the motherboard to store small amounts of data in active memory.
What kind of battery is in a desktop computer?
A coin-cell battery (CR2032) powers the real-time clock and CMOS memory. When the computer is not plugged into a wall socket, the battery has an estimated life of three years. When the computer is plugged in, the standby current from the power supply extends the life of the battery.
