php editor Yuzai: Can’t the system start normally after replacing the computer motherboard battery? It may be caused by the following reasons: 1. The battery is not installed correctly or does not fully contact the motherboard. 2. The battery is low or damaged. 3. The CMOS settings on the motherboard are reset, causing the system to be unable to recognize the boot device. 4. Other hardware failures, such as problems with memory, graphics card, hard disk, etc. It is recommended to check whether the battery is installed correctly and try to replace it with a new one. If the problem persists, please check whether other hardware is faulty, or send the motherboard to a professional repairman for inspection and repair.
# Can’t start the system normally after replacing the computer motherboard battery?
Generally, this situation is caused by oxidation or poor contact of the memory gold finger. When encountering this situation:
1. Unplug the computer power cord first and press the power button on the chassis 5-6 times. Release the residual charge on the motherboard.
2. Then open the side panel of the chassis and insert and remove the memory slots. 3. Remove the CMOS battery from the motherboard and reinstall it after 1 minute. 1. 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 battery is insufficient, the time will return to the factory date. It also records the hardware information used during startup, that is, to maintain the CMOS BIOS. information. The motherboard battery can be recharged when there is no power during use. Open the main case. Near the south bridge on the motherboard, there is a silver-white disc button battery with a plus sign on the back and a diameter of about two centimeters. 2. The batteries on the motherboard of our computers are all lithium batteries, which can be charged when connected to the power supply. A motherboard's lithium battery can be used for many years. If the motherboard BIOS is frequently lost, we need to buy a new battery to replace it. If the power still drops frequently after replacing a new battery, then the reason is that the motherboard cannot charge the battery.
Can the computer be turned on if the motherboard is broken?
"The motherboard is broken." Whether it can be booted depends on the degree of damage. If the computer can occasionally turn on, it means that the computer motherboard is not completely broken. It may also be that the motherboard is not damaged, causing the computer to fail to boot.
1. The questioner affirmed that "the motherboard is broken." If the repair shop owner reports that the motherboard is broken, you should ask clearly what parts of the motherboard are broken;
2. If many components of the motherboard, such as network cards, sound cards, and USB ports are broken, generally it will not affect the normal startup of the motherboard. , and displayed normally. Even if there is no display on the monitor, you can still determine the working status of the motherboard. It will be silent only if important parts are damaged. For example, on the motherboard: various components and equipment power supply modules, memory, bridge chips, graphics cards, startup circuits, BIOS, etc.;
3. If it can be turned on occasionally, it means that the motherboard is slightly injured. Sometimes the motherboard is not faulty, but there is a problem with the board device plugged into the motherboard, which can lead to people mistakenly blaming the motherboard. Such as poor contact between memory and independent graphics;
4. If possible, you can use hardware "minimization" to detect whether the motherboard is really bad. If the motherboard is removed from the chassis, only the motherboard, CPU, memory, power supply, keyboard and mouse, and monitor are used, and the power is turned on to verify whether the motherboard can light up the monitor, and you will know. At the same time, you can also find out whether there is a problem with a certain component.
The motherboard is powered on but cannot start?
There are many reasons why the motherboard cannot start after power on. It may be caused by the CMOS battery on the motherboard being out of power and the battery needs to be replaced.
It may be caused by poor contact between the gold fingers of the memory stick. You can Unplug the memory stick and then reinsert it for use;
It may be caused by poor contact with the graphics card and you need to reconnect the graphics card for use.
If the motherboard is broken, can it still be turned on and used normally?
This is not absolute.
1. If the motherboard is broken, there will be no power. In this case, the computer's power button and restart button will have no effect. If the problem occurs suddenly, check the switch wiring and if there is no problem, the motherboard is damaged.
2. If there is a problem that it cannot be started, check the wiring port and the motherboard wiring. Sometimes the motherboard is not powered by dust or loose wiring. Reseat the line interface on the motherboard.
3. This problem will also occur when the motherboard cannot read the memory card and the hard disk does not match. If the hardware has been replaced recently, check whether it matches the motherboard.
4. If the hardware has not been changed recently, you need to re-plug and unplug the wiring. Poor contact is the main cause of computer motherboard problems. Because the motherboard has many parts and interfaces.
Can’t start the computer after replacing it with a new motherboard?
Solution:
1. Plug in the power cord tightly, check the plug on the plug board, and confirm that the plug board is powered on.
2. Confirm that the wire from the host power supply to the plug-in board is good, then take the power supply and connect it to the 24P plug of the motherboard. Short-circuit the green and any black wires. If the power fan turns on, it means there is no problem with the power supply and the power fan does not work. It means the power supply is broken, replace it with a new one.
3. After confirming that there is no problem in the above 2 steps, unplug the switch wire connecting the motherboard and the front panel of the chassis, and use a screwdriver to short-circuit the two pins of the switch. If the fan rotates, it means there is no problem with the motherboard. If the fan If it doesn't turn on, it's probably a motherboard problem, so contact professional maintenance personnel to handle it.
4. Short-circuit the motherboard pins and the fan will rotate, but there is no response when pressing the switch button on the front panel. This means that the switch button is broken or stuck. Replace with a new switch button, or remove the stuck button.
Colorful motherboard boots directly into bios but does not start?
The reason for booting into bios is because the computer cannot find the boot file. The possible reasons are 1: The hard disk is not recognized. Check whether the hard disk power cable and data cable are connected properly. If the connection is OK, your hard disk may be broken.
2: If you can see the hard disk in b ios, your system boot may be broken and you need to redo the system.
3: If 2 hard drives are installed, check whether the first boot sequence is correct.
Can the computer still be turned on if the motherboard is broken?

The motherboard memory slot light is on but cannot be started?
The reasons are as follows
1. Power supply problem. Although the motherboard light is on but the computer does not turn on, there is a high possibility that there is a problem with the power supply, such as the power cord is not connected properly, the power supply is damaged, etc. The troubleshooting method is to unplug the power cord and plug it in again, then try to turn it on. If it doesn't work, replace it with another power supply. If it returns to normal, it means there is a problem with the power supply.
2. Memory problem. If there is a fault in the memory, such as oxidation or poor contact, the motherboard will light up but not turn on. You can first remove the memory module from the motherboard, then wipe its gold finger, and then put the memory module back on the motherboard. Try installing it in another card slot and see if you can boot it again.
3. Graphics card problem. When there is a problem with the graphics card, the computer cannot be turned on. The method is to remove the graphics card first, and then directly connect the monitor to see if it can be turned on. If there is a problem with the graphics card connection or the graphics card itself, the graphics card needs to be replaced in time or the graphics card must be reset. Plug it in.
4. Motherboard problem. If the motherboard light comes on after turning on the computer and the fan on the radiator runs normally, there may be a problem with the motherboard. You can use a screwdriver to short-circuit the two pins on the motherboard switch. If the fan does not spin, the motherboard is faulty and the motherboard needs to be replaced.
How to enter the bios settings if the ASUS motherboard cannot be turned on after the memory is increased?
1. Open the case to discharge the BIOS. Now there is a special BIOS discharge jumper on the motherboard (near the button battery). Jump to the other side and then jump over again.
2. Remove the battery, short-circuit the positive and negative electrodes of the battery holder for a few seconds, then reinstall the battery, and it will generally start.
In addition, in order to avoid being unable to boot after overclocking failure, many motherboards now also provide such a function, that is, after overclocking failure, you can enter the BIOS reset by holding down the Del key when booting. If your motherboard supports it, you can press and hold the Del key during boot to enter the BIOS reset. Expansion: The actual significance of memory overclocking is not very great, and the improvement effect is not too high. It mainly depends on the overall performance of the platform, and memory overclocking is harmful to the memory. There are two types of memory overclocking. One is to adjust the main frequency and voltage of the memory to achieve the overclocking effect if supported by the motherboard BIOS. The other is that the motherboard and memory themselves cannot support high frequencies, and the SPD information of the memory needs to be modified. This is achieved by forcing the low frequency to work at high frequency.
