php editor Xiaoxin will answer for you: The computer motherboard cannot be turned on after replacing the battery. It may be because the battery is not installed correctly, the battery contact is poor, or the motherboard is damaged. Solutions include reinstalling the battery, cleaning the battery contacts, checking the motherboard connection lines, etc. If the problem is still not solved, it is recommended to contact professional technicians for repair.
The motherboard battery is used to record the computer system time and motherboard hardware configuration information, that is, to maintain the accuracy of the system clock and configuration information. When the battery is insufficient, the time and configuration information will return to the factory date, and the startup will be recorded. The hardware information to be used is to maintain the bios information. I haven't done much research on it myself, but there are still situations where the button battery is out of power. It can only be said that it generally lasts for three or four years without any big problems. Also, if the computer cannot be turned on after being idle for a long time, you can try discharging it
Steps to replace the computer motherboard battery:
The first step is, near the south bridge of the motherboard, there is a silver-white disc button battery with a plus sign on the back and about two centimeters in diameter.
The second step is to use a flat tool to press the latch on the CMOS battery holder.
The third step is to pop up the battery on the motherboard automatically and then take it out by hand.
Installing the battery: Place the side without the buckle first, then place the battery flat on the slot, press it with the side, and there will be a click. The battery replacement is completed.
Before disassembling the battery, please note:
1. Remove your own static electricity by touching iron objects with your hands.
2. Unplug the CPU, graphics card, hard disk and other devices on the motherboard.
3. Pay attention to the battery model. Now it is generally CR2032.
1. Can be swapped 2. Because the startup and restart buttons of the motherboard battery are connected to the motherboard through a connecting cable, you only need to unplug the connecting cable and swap the two buttons. 3. Before swapping, you need to turn off the computer and unplug the power cord to avoid accidents such as electric shock. At the same time, when swapping buttons, you need to pay attention to the direction of the connecting cable to ensure that the connection is correct.
How to remove the battery cable:
The first method is to use a hidden buckle cable. This kind of cable arrangement is usually distributed on the keyboard and the touch panel of the notebook. If we remove the computer casing, we will find that the color of the interface is very different from the color of the base. And the cables are also wider. In this case, we usually use a sharp object (such as a paper clip or the like) to push out the keychain of the interface.
The second type is the socket interface. This kind of cable is installed in fans, batteries and other devices adjacent to the computer motherboard. After also removing the outer pit, you can find several red and white combination wires inside. Some are wrapped, some are not. These wires are usually connected to the motherboard, speakers, and fans. Their interfaces are designed to be relatively wide, so you don't need to use tools to remove the cables. Use your fingernails to grab the protruding object, and slowly shake it out slowly. If the handle cannot be taken out, we need to use tools to push the wider part outward, which can also be removed.
The third locking cable arrangement. This cable is also located within the keyboard and touchpad. This kind of cable arrangement is usually found in ultrabooks. In order to cater to market demand, manufacturers make notebooks as thin as possible, so that the electronic components will not overlap and will only be roughly parallel. When removing this type of cable, you will find a lock that is very different in color from the surrounding interfaces. After finding the lock, use a flat-blade screwdriver to gently pry upward to open the lock.
The fourth step is to lock the handle. This lock is located at the connection axis between the keyboard and the screen, and it is also a key part for guiding keyboard commands. Because its interface is similar to a door handle, we call it this. When we need to dismantle it, we only need to hold something similar to the handle device and lift it hard, then insert a flat-blade screwdriver into the lower interface and gently pry it up, then gently pry it up at both ends, and you're done.
