This article mainly introduces the use of the battery on the motherboard in the PC. It is very detailed and has a certain reference value. Interested friends must finish reading it.

There is a battery on the motherboard of the PC, and its function is to power the CMOS chip after the computer is powered off, so as to keep the information in the chip from being lost. The motherboard battery is used to record the time of the computer system and the hardware information to be used at startup, that is, to maintain the BIOS information of the CMOS.

The operating environment of this tutorial: windows7 system, Dell G3 computer.

The motherboard battery is used to record the time of the computer system, that is, to maintain the accuracy of the system clock, when the power is not enough, the time will return to the factory date, and record the hardware information to be used at startup, that is, to maintain the BIOS information of the CMOS.

Ordinary microcomputer motherboard batteries are generally CR2032, which can not be recharged in the process of using them. It is a misunderstanding to think that the motherboard battery is rechargeable. CR2032 packaging or battery body marked lithium battery or LITHIUM, refers to the lithium compound battery, not lithium-ion battery, can be charged by the latter.

Position

Open the main chassis, near the south bridge on the motherboard, there is a silver-white round button battery with a plus sign on the back and about two centimeters in diameter.

Replace

A button battery on the motherboard can last for many years, but if the motherboard BIOS often falls off, then we need to buy a new battery to replace it. The specific steps to replace the motherboard battery are as follows:

1. First buy a new button battery, pay attention to the lithium manganese button battery model CR2032. If your machine is a brand machine and is under warranty, you can contact customer service for replacement, please do not open the chassis by yourself, otherwise the warranty will be cancelled. If it is a compatible machine (assembly machine), you can take it apart and do the above operation.

2. Turn off the power of the computer. Open the lid of the chassis and you will see a round battery. The diameter is about 1.5-2.0CM, take out the battery, the battery holder of each motherboard is different, so the method of battery selection is also different. It is generally divided into three types: outer button type, upper pressure type and upper button type. Carefully remove the battery, then press the clip on the battery slot, and the battery pops up. Because the battery holder on each motherboard is different, there are many ways to remove the battery. There are three more common types-"outer button": to remove the battery, just press the button next to the battery holder down, and then push the battery out; "top button": the button of this battery holder is made on top of the battery. When you want to remove the battery, just pull the button out, and the battery will pop up automatically; "up press": it's easy to remove the battery, just push the battery out.

At this time, take out the new battery and install it. Pay attention to the positive and negative direction of the button battery, and then install the battery back according to the reverse action of just removing the battery. Then close the cover of the chassis. Then restart the computer to set up the CMOS.
