Strange things can happen to your computer. The date and time are lost every time the computer is turned off; when the computer boots, "strange" messages appear that there have been changes in the BIOS, although you have not changed anything in it. These symptoms indicate that your computer is low on battery. This battery is located in a special slot on the motherboard and is easy to replace.

Instructions
Step 1
Before changing the battery, you should buy it. You need to purchase a CR2032 battery. It looks like a flat tablet and is sold in many computer stores.
Step 2
Unscrew the screws securing the side housing cover and remove it. Access to the motherboard will open. Find a battery. This is not difficult, it is usually installed in the socket with the marking upwards, and there are no other parts similar to it on the motherboard.
Step 3
Remove the old battery. To do this, gently bend the latch on the socket, and the battery rises above its edge. Grasp the battery with your fingers and pull it lightly. During these procedures, be very careful not to damage the surface of the motherboard and the parts adjacent to the battery socket.
Step 4
Install a new battery to the motherboard. The battery should be positioned on a smooth surface with the markings facing up. In this case, the latch must securely fix it in the socket.
Step 5
Close the lid of your computer and turn it on. Set the parameters in the BIOS, if necessary, and adjust the date and time. Check if the computer settings are no longer reset at shutdown.
