The main component is the motherboard, and many parts are attached to it, including a small battery. It is needed to save some settings and keep the system clock running.

For stable operation of the system date display, it is recommended to change the battery, moreover, the battery partially affects the stable operation of the entire computer.
Step 2
Before you start replacing the old battery with a new one, disconnect all wires from the mains. To avoid causing static electricity, use a screwdriver to touch any metal object.

Press down on the side bar of the battery holder, it should jump out of the connector by itself.
Step 4
