Miniature battery similar to those used in desktop computers.
One of the desktop computer's system-boot functions is to check the voltage of its internal battery. The ominous message "system battery voltage is low" can occur during this system-boot phase if the internal battery voltage is low.
Battery Purpose
The internal battery in your desktop computer provides power to the CMOS memory chip, which stores the time, date and configuration of your computer, including the peripherals. Without this information, the computer will not function properly.
Type and Location
Most desktop internal batteries are 3-volt lithium devices and are widely available. The battery is located on the motherboard. Always use the correct replacement part number when replacing the battery.
Installation
Installation is straightforward, but care should be taken because the battery sockets are often fragile; a broken battery socket becomes an expensive problem. Do not remove the old battery until you are ready to insert the new one. Minimize the time the computer is without a battery; your computer is at risk for loss of setup data when there is no battery.
