Computer shutdown fan non stop? Why is the fan still running after the computer is turned off?

Causes of the fan after the computer is shut down.

1. There is no advanced power management support for the computer.

If this is the case, then click on "Start" "Settings" "Control Panel" in that order.

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 BIOS.

Go to the BIOS and select the Advanced Power Management option. Try to modify the power management options in the BIOS, if you are not familiar with the BIOS at all, go to the BIOS and select the "Load Default Setup" option, which is to restore the BIOS to the default settings at the factory.

3. APM NT Legacy Node is not enabled.

In general, if the APM NT Legacy Node is not turned on, it may cause the power to shut down, but it cannot automatically cut off the power supply. Go to Device Manager.

Click "View Show Hidden Devices" in the menu bar to show all hidden devices in the system. In the Device List box, check whether the APM NT Legacy Node option is available. If your computer supports this feature, you will have this option, double-click it, and in the pop-up properties dialog box, click the "Enable Device" button.

4. Shutdown group policy.

Click "Start" "Run" and then type in ", an interface will come up, and then select the computer management management template system on the left, "Windows system will not turn off the system power after shutdown" If this item is not configured or enabled, then change it to disable OK.

5. The problem of driving.

Click on My Computer, right-click and select "Manage" "Device Manager" Click on the computer to see if there is an exclamation mark or something, and if it is an MPD Uniproccer PC, or a standard PC, it is best to redo the system, or an advanced power management driver from the Internet, and then reinstall it.

6. Hardware problems.

You can try to change the power supply, if this problem still occurs after changing the power supply, it is a problem with the motherboard, this power management module is broken, change the board, or take it to the place where the board is repaired to repair it.

If this situation occurs on the computer, it is generally caused by the computer not being able to shut down normally, and you can try the following methods to solve it:

1. In BIOS, go to Energy Management, turn on ACPI, and set it to S3.

2. Control Panel Power Options, enable hibernation or advanced power management.

3. Modify the registry: open the registry (start running and enter regedit), find the "hkey local machine software microsoft windows nt currentversion winlogon" branch, find or create a reg sz registry key in the right pane, the name is "powerdownaftershoutdown", Double-click to set its value to 0, exit the registry when you're done, and restart your computer.

The fan will stop because after your computer is turned off, the computer will still have heat, and then the fan will run to dissipate heat. If it is said that the fan keeps spinning, then there is a problem with the fan. You need to go to the computer store to disassemble it and fix it.

Stop, but it will be delayed, and the fan will not stop working until the heat in the computer dissipates.

There is a problem with the computer. Turning off the power is equivalent to powering off, why does the fan rotate? Is this the case with all other people's computers?

Just turn the power off and you're good to go.

Then you're amazing, I'm afraid it's a fake shutdown!

Taking Windows 10 as an example, the fan is still running when the computer is turned off, it may be because the fan is faulty, or there is a problem with the computer settings, resulting in the power supply not being turned off normally after the computer is turned off. Repairs can be made by changing the computer settings or by contacting a service person.

The solution to the fan is still running after the computer is turned off is divided into seven steps, and the specific operation steps are as follows:

2. After entering the power and sleep settings page, click "Other Power Settings" to enter the "Power Options" page.

3. Then select "High Performance".

4. After that, press and hold the "win+r" key at the same time, enter " in the running window that appears, and click on the suiding.

5. After entering the "Local Group Policyr" interface, find "System" in "Management Template" and double-click to open it.

6. In the "System" page, find and double-click "Win10 does not turn off the system power after the shutdown occurs".

7. Finally, select "To Disable" and click "OK".

First of all, check the memory module for dust, if not, skip it, if there is, remove it and wipe it back and forth with the eraser 2 times at least 6 times.

If not, then look at whether the hard disk indicator next to the button flashes when you turn it on. If it doesn't flash, it may be that there is a problem with the power supply of the motherboard, check whether the capacitor on the motherboard is bulging or cracked, I estimate that it is generally caused by this problem, and you have to go to the repair station to replace it. If it is not found, it may also be a problem with the chip.

Step 1: If you encounter the problem of stopping and turning the fan down, you should check the memory module and unplug them one by one to test the boot status. If it can be turned on and won't restart, it's a memory problem, if not, it's not memory.

Step 2: If the memory detection is okay, it still can't be turned on, and the CPU fan still stops and spins, check whether the host power supply is good, and the detection method is to replace the finger stool method and test it with other new power supplies. If it can be turned on and will automatically restart, it is basically a problem with the power supply.

Step 3: If the problem cannot be solved, consider detecting the motherboard, which may be the motherboard's protection.

Note: If you can open the only sales travel plane and it will automatically restart, it is likely to be a system problem. However, this problem is generally rare, and it usually appears on old computers, so you can try to see if reinstalling the system can solve it.

After the computer is turned off, is the fan completely turned off?

Hello dear! Answering for you: Yes, in general <>

When your computer is turned off, your computer's fan will usually stop running. However, there may be exceptions due to differences in the number of computers of different brands, models, or configurations. Take laptops as an example, many computers will continue to run after shutting down, the reason is that the design of the cooling system of laptops is more complex, in order to ensure the effect of the cooling system, it is often necessary to design multiple fans, some fans may be directly connected to the battery, not the motherboard, so even if the computer is turned off, these fans will continue to run for a period of time until the battery is exhausted.

For desktop computers, most of the time, the computer's fan will also stop running after the shutdown. Only in exceptional circumstances, such as poor heat dissipation or overclocking, which causes the computer to be hot, is it possible for the fan to continue to run after the shutdown. At this time, it is necessary to solve the problem by replacing the radiator and cleaning the fan on the computer.

In general, although the fan will stop running in most cases after the computer is turned off, it still needs to be judged and dealt with according to the specific situation! Dear, I hope I can help you! ^_

After the computer is turned off, is the fan completely turned off?

Dear, yes, after the computer is turned off, the fan stops even if the cavity is completely closed. But that doesn't mean the computer is completely turned off. The details are as follows:

1.If the computer is shut down in the operating system: After the computer is shut down, the operating system will send a shutdown command, the computer will enter the shutdown state, and the fan will stop rotating.

However, hardware devices such as power supplies, motherboards, and memory are still powered on, and the power supply needs to be cut off by means such as a wide source switch or unplugging the power cord. 2.If it is a direct power off shutdown:

After the computer is shut down, you can cut off the power supply by directly unplugging the power cord or turning off the power switch, at which point the fan will stop and the computer will be completely turned off. Therefore, if you need to turn off the computer completely, it is recommended to use a power switch or unplug the power cord to cut off the power. At the same time, it is recommended to save the data and close the assigned program before shutting down the computer to avoid data loss or program abnormalities.

The computer boot fan will pause and then can't turn on Hello dear, analyze the reasons, from the most common to the rare reasons, in order: memory - motherboard - power supply. Here's how to solve the problem:

1. Memory. This is the most common and most common cause. The vast majority of them are caused by poor contact, you can remove the memory module, wipe the gold finger on both sides with an eraser or alcohol, wipe the oxidized metal surface clean, clean the memory slot with a dry brush, or insert the memory module into another memory slot, if there are more than two memory, you can run the test on a single strip to eliminate the fault memory module.

If it doesn't work at once, you can wipe it several times, so that most people's problems can be solved. (If you have a discrete graphics card, you can also clean it up, and the operation method is the same as the memory module). If you still can't start the computer normally, you can change a memory module of the same model for testing, if you change the memory module can be solved, that is, the original memory module is damaged, just buy a new one.

2. Motherboard BIOS error. Motherboard BIOS errors can also cause this problem, you can discharge the motherboard, that is, reset the BIOS, remove the coin cell battery from the motherboard, leave it for a few minutes, and then install it back. If there is a jumper, it is also possible to use the jumper short.

3. Internal dust or static electricity. After a long period of use, the computer will inevitably accumulate a lot of dust, and sometimes dust will cause some parts to be in poor contact. It is recommended to use a high-power hair dryer or air pump for dust removal operations.

4. Power failure. If none of the above methods can be restored to normal, then it may be a power failure, which will be caused by a burned power supply or too low power. The solution is to change a power supply test, the general family does not have the conditions, you can go to a professional repair shop to find him to help you test, if you change the power supply, just buy a new one.

Bridge age 5, motherboard. If you still can't start the computer normally after changing the power supply, then you have to consider that the motherboard chip is faulty. The same is to let a professional repair shop test for you, if you can repair the motherboard, if it is not easy to repair or too expensive, it is better to directly change a motherboard.

Summary. Hello, this situation may be a power failure or not enough supply voltage. Inspection Method:

If you encounter the problem that the fan stops and turns down, you should check the way the memory module is detected, unplug them one by one, and test the boot status. If it can be turned on and won't restart, it's a memory problem, if not, it's not memory. If the memory detection is okay, or can't turn on the CPU fan or still stop and turn down, check whether the host power supply is good, the detection method is the replacement method, test with other new power supplies, if it can be turned on, it will automatically restart, it is basically a power supply problem.

If it still can't be solved, consider detecting the motherboard problem, which may be the motherboard's protection. If it can be turned on, it will automatically restart,It's likely to be a system problem.,But generally this problem is relatively rare.,Generally appear on old computers.。 You can try to see if reinstalling the system can solve it.

The laptop suddenly turned off instantly, the fan stopped instantly, and it couldn't be turned on.

Hello, this situation may be a power failure or not enough supply voltage. Inspection method: If you encounter the problem of stopping the fan and turning it down, you should check the memory module to check the way of wax test and unplug it one by one to test the boot status.

If it still can't be solved, consider testing the motherboard problem, which may be the motherboard's slippery protective effect.

If it can be turned on, it will automatically restart,It's likely to be a system problem.,But generally this problem is relatively rare.,Generally appear on old computers.。 You can try to see if reinstalling the system can solve it.

It's not that I'm a laptop.

Moreover, it is an instant shutdown and an instant stop of the fan, the battery is full, and it can't be turned on directly.

The power button was pressed.

Will it be bright. There is no sound of starting.
