The laptop suddenly shuts down when it turns on???

Laptop automatically shuts down and powers off; The common reasons are: first, caused by poor heat dissipation, it is enough to disassemble the machine to clean the fan or replace the fan; Second, the BGA (north-south bridge, graphics card) packaging chip on the motherboard is damaged by virtual soldering, which needs to be repaired and solved. It is recommended that you send it for repair and testing.

It is recommended that you find a reputable and skilled repairer to help you with the repair.

If you have any questions, you can consult me, and I will help you in Beijing.

Upstairs is right, sudden shutdown will first suspect heat dissipation problems, boot for a period of time to touch the heat dissipation port and other parts are not very hot, if it is very hot, it is simple to clean up the dust around the fan, in addition, the CPU thermal grease is dry, silicone grease is used to improve heat dissipation capacity, if there is no silicone grease may cause heat to be difficult to dissipate, automatic shutdown, can not be dealt with can find after-sales. There is also a high indoor temperature, you can buy a cooling pad.

If it doesn't get hot, it could be a software problem, but most software problems result in a failure to restart.

There may also be hardware problems such as power supply and memory, you can preliminarily judge that if it is often shut down, it is recommended to go for maintenance.

The next temperature measurement software looks at the specific temperature, if the temperature is high, it is a problem of heat dissipation, it is overheating and shutdown, you need to disassemble and clean the fan, the fan shaft is cleaned and refueled, and the temperature is normal, it will not be shut down. If the temperature is normal, it is a problem with the motherboard, and the graphics card or power chip is faulty.

Help solve computer-related problems, and ask directly if you have any questions, you don't have to be polite. You can ask questions directly or hi, and I can also have buckles and ** consultations in my profile. Beijing can find me, and other provinces can also guide relevant precautions.

The machine is too hot.

Downstairs The power supply problem will show the voltage without a blue screen, and the irregular restart of the memory and hard disk will be restarted after the blue screen, depending on how you set it up, the CPU overheating is slow, the card crashes, and the graphics card overheats up, and this direct power failure will occur.

1.The reason for the sudden shutdown of the computer is because the system overheats due to high weather temperature or insufficient program maintenance, which causes the computer to shut down automatically. It is recommended to check whether the fan is working properly and check whether the system temperature is normal with software.

2.Computer memory. When the memory is in contact with the motherboard socket is loose, it may cause the computer to shut down automatically.

It is recommended to check whether there is a power supply that is plugged into the motherboard, or you can unplug the change slot. 3.Computer power supply.

Computer software reasons. Viruses or Trojans invade your computer and cause it to shut down automatically, which is the experience of many netizens. It is recommended to use antivirus software to completely disinfect the virus and then restart the computer.

5.The computer hits the dispenser too hot. The PC fan tray is unstable, resulting in insufficient heat dissipation capacity of the PC fan, and the courage is too high, and the motherboard's automatic protection function will automatically shut down.

6.The motherboard is prone to deformation, probably because the host voltage is unstable. Replacement.

7.When the host power supply fails, or the host voltage fluctuates greatly, you can add an AC regulated power supply. 8. If it is not in safe mode, it is recommended to kill the virus in safe mode, or reinstall the system after disconnecting the network to eliminate system problems.

It is recommended that you go to a professional computer repair station for repair. Please do not split it at will, otherwise even the computer hardware device may be damaged. Then check if your computer has been infected with malicious viruses.

Feature you to use Kingsoft Guardian to kill the virus Trojan. Because Kingsoft Guardian is different from traditional killing software, it can not only kill Trojans, but also repair the damage caused by viruses to the system. Finally, check whether it is the setting of some application software, such as **application software, anti-virus software, etc.), and then check whether there is an option to check the sudden automatic shutdown in the scheduled task.
