Possible causes of automatic power outages:
First, after automatic shutdown If it can be turned on normally, then this situation belongs to the self-protection function of the system.
When the computer is overloaded or encounters other conditions that damage the CPU or system, poisoning, CPU usage is often 100 and so on. In order to protect the CPU from damage, the system automatically loses power. It is recommended to optimize the system.
Second, poor heat dissipation, which generally occurs when the CPU is overheated or the CPU is overloaded due to the long-term operation of the computer. Excessive dust and improper fan operation will lead to poor heat dissipation and overheating of the CPU, which will trigger the automatic power-off protection function. If this is the case, you need to clean the laptop fan, radiator.
3. Automatic power failure caused by external devices, removal of newly installed hardware devices, such as external cameras, printers, including upgraded memory, etc.;
Fourth, the notebook itself is faulty and needs to be specifically detected.

The causes tend to focus on incompatible hardware and drivers, problematic software, viruses, etc. Workaround:
1. The cause of the virus. Use PC Manager to disinfect the virus.
2. Reasons for memory. Use an eraser to wipe the gold finger of the memory module and wipe off the oxide layer to ensure that the memory module is installed and running normally.
3. The chassis is not clean. The CPU fan has too much dust to run normally, causing the CPU temperature to be too high, so use a brush or hair dryer to clean up the dust on the inner wall of the case, the CPU fan, the graphics card fan, and the motherboard.

The laptop automatically shuts down, generally due to the following reasons:
Shanghai Notebook Repair Center 400-669-9965
1 The computer system is poisoned or infected with malware.
2 CPU Fan Bad CPU Temperature Too High, Overheating Protection.
3 The power supply is bad, or new hardware has been added, and the power supply is insufficient.
4 The graphics card or graphics card fan is broken.
5 The motherboard is broken, and the motherboard core is overheating.
Solution: 1 Check whether the antivirus software has killed the virus, you can determine whether it is caused by the computer system poisoning or malware, if there is a virus, it is recommended to use a combination of antivirus software to kill the virus, or if it doesn't work, go to the maintenance center to solve it.
2 Test the temperature of each hardware on the computer, open the case, see if the CPU fan and graphics card fan rotate normally, find out the problem, and go to the maintenance center to replace the CPU fan. Different computer models have different CPUs**, which need to be detected to know**.
3 If the computer has a discrete graphics card and the power supply is not enough, you can only go to the repair center to change to a higher power power supply.
4 Shut down, touch the south bridge, north bridge chip, graphics card chip of the motherboard with your hands, if it is very hot, it is likely that the motherboard is damaged and needs to be repaired immediately.

The automatic shutdown of the computer is mainly caused by the following reasons: >>>More
Generally, the automatic shutdown may be caused by the high temperature caused by too much dust in the CPU fan, if so, clean the CPU fan and heat sink. >>>More
After booting up, press F8 to enter safe mode, and then exit, select Restart or Shut Down to boot on, you can enter normal mode (repair registry). If the fault persists, please use the system restore that comes with the system to restore the repair to the time when you did not have this fault (if the normal mode recovery fails, please boot the computer and press F8 to enter the safe mode and use the system restore).
Basically, it's a software problem, enter the PE system to try, if it's still like this, it means that there is a problem with the hardware. Software problems only need to reinstall the system, it is recommended to install it with the original image.
