As soon as the laptop is turned on, the fan spins wildly and then turns off

It could be that there is a problem with the CPU heatsink.

After turning on the computer, the CPU heats up rapidly, so the speed of the cooling fan increases rapidly, but the heat sink is damaged, causing the fan to fail to cool the CPU, causing the CPU to shut down after reaching a certain temperature.

If it is a desktop, it is recommended to disassemble the case, remove the CPU cooler, and apply some heat dissipation silicone to try it. But the notebook is recommended to go to the after-sales service.

Hello! First of all, the following answers are not network replication, but are the essence of my practice and communication!

Blue screen: Don't panic! Take a closer look and give it a try. (0 0) Don't go into the question of what ** means, you'll never figure it out!

Solving the problem is the key!! The reasons for the blue screen tend to focus on incompatible hardware and drivers, problematic software, viruses, etc. (The above ** is usually caused by a faulty driver or system service.)

Suggestion: Please rule out the problem as follows: 1. Touch the temperature of the CPU. Whether it is too high. Look at heat dissipation. 2. Whether the hard disk connection is loose; After there is no abnormality, check the hard disk for error;

3. If there is any virus in the system, it is recommended to scan and disinfect the virus in safe mode;

4. Try to restore the BIOS to its factory state;

5. Is the driver of the hardware installed successfully after installing the system?

6. It is best to reinstall the operating system first; 7. If there is still a problem after reinstalling the system, it is very likely that the hardware is incompatible; 8. Consult with the merchant or friends who are familiar with the computer, maybe they will help;

9. Good luck! I hope I can help you!

It's a bit like low voltage, isn't the voltage unstable.

After dismantling, did you throw away the silicone? You're really capable, people are repainting, you just don't want it. It's strange that it's not hot.

Silicone replaced? Or not? Has the CPU graphics card been recoated with silicone?

It may be a power supply problem My desktop also encountered such a problem because the power supply fan does not rotate What is the specific problem of the landlord depends on the specific situation!

Summary. The laptop starts and the fan turns off.

Hello dear, For this problem, we must look at the essence through the phenomenon.

It seems that it is because the fan turns that it causes a forced shutdown, in fact, the real reason is not in the fan, of course, no one will do this test, if you do this test, you will remove the fan and it will also be forced to shut down.

How to determine the real cause:

1. Try using the battery alone to start the computer.

2. Remove the battery and use the charger alone to start the computer.

If you can't find the cause, then the motherboard is broken.

The computer won't turn on.

The laptop starts the fan and turns it off, and the computer can't be turned on, hello dear, 1Have you changed a power supply, it should be a problem with the power supply, no power supply, loss of lead If there is no problem with the power supply, it is a problem with the motherboard, see if the motherboard capacitor is bulging, there is a direct purchase of the same model of capacitor welded, the capacitor is not a problem is the chip. 2.

There should be no problem with your power supply, it's the switch on your motherboard that has a problem, you take off your motherboard switch, turn it on with the key, and plug it back in! 3.The line is a short circuit fault, caused by the automatic protection phenomenon, see the discussion of early delivery to the professional point maintenance!

4.A short circuit in the motherboard power supply caused by overclocking. The power supply is automatically protected so you can't turn it on.

If you know someone, you can sell the direct warranty. If you don't know it, you can only change it. 5.

Sometimes in the process of using the computer, I suddenly find that the fan is still turning after the computer is turned off, and the power light is not extinguished, how to fix this problem? Below I will teach you the solution that the fan is still spinning after the computer is turned off, for your reference.

In most cases, it is due to the storage of power on the motherboard, which causes the computer to not be able to shut down.

So first open the case cover.

Then locate the motherboard battery.

After taking the motherboard battery off, listen to it for a while (a few minutes).

After booting up, you may be asked to reset the time, and you can enter the system after resetting.

Speaking of which, although there may be many reasons, but based on personal experience, it is more likely that there is a problem with the power supply or motherboard or CPU fan pins and plugs. Generally not a big problem, Let's talk about it in detail, after the computer is softly shut down, if the CPU fan and power supply fan are still running, the solution to the problem should be considered from the following aspects:

1. Your computer does not have advanced power management support turned on.

If this is the case, then you need to click "Start" "Settings" "Control Panel" "Power Options" "High Energy Power Management" and then check "Enable advanced power management support".

2. There is an error in the advanced power management settings in the motherboard BIOS.

It is also possible that you have mistakenly modified the advanced power management options in the BIOS (Advanced Power Management in the BIOS), enter the BIOS, and press the delete key when your computer is turned on. Once there, select the Advanced Power Management option. Try modifying the options in the BIOS regarding power management.

If the first item is enable, then you change it to disableBut if you are not familiar with the BIOS at all, then follow the method I told you, go into the BIOS, and simply select the "Load Default Setup" option, that is, restore the BIOS to the default settings at the factory.

3. APM NT Legacy Node is not enabled.

If the laptop won't turn on and the fan turns off, it may be because the hardware inside the computer is malfunctioning. In this case, it is recommended that you take your computer to a professional repair shop for repair as soon as possible.

Here are some possible reasons:

The CPU inside your computer may have overheated, causing the fan to not work properly.

The fan itself may be faulty and not working properly.

The internal cooling system of the computer may be damaged, causing the fan to not work properly.

The power management module inside the computer may malfunction, causing the fan to not work properly.

Therefore, it is recommended that you accompany Bu to send the computer to a professional repair shop for overhaul to ensure that the computer is working properly.

If there is a problem with the power supply system, send it for repair.
