The laptop cooling fan does not rotate, and the CPU uses Green 100

This kind of fault is mostly because the fan is dirty or damaged, and it is mostly dirty, and it will be okay to send it for repair and dismantling, and if it doesn't work, you need to replace the fan.

I'll help you in Beijing.

If you are not in Beijing, it is recommended that you find a reputable and skilled repairer to help you overhaul.

When the CPU is used at 100%, the wind dissipation should have been spinning!!

High CPU usage will cause high temperatures, but high temperatures will not affect CPU usage.

The usage rate reaches 100%, which is caused by running large software or viruses.

For example, when I play King of the Battlefield, the CPU usage reaches 100%, the wind dissipates and the CPU temperature swings back and forth around 53 degrees.

If the CUP temperature is high, there is a risk in your computer, the computer performance will deteriorate, the CUP usage has a lot to do with your memory usage, but under normal circumstances, the CPU usage will not rise to 100%, if it rises to 100%, it means that your computer is not running normally, if it changes up and down in between, there is a great possibility of being infected with the virus, you can't dissipate heat, the temperature is too high, of course your computer is not working properly, and the CPU is not running normally.

Obviously there is a relationship, the CPU is definitely high at full load.

Of course.. If the CPU is used at 100%, it is operating at the limit. Of course the temperature is high!

Don't bother with it, redo the system.

Probably the fan is normal.

Cards are other reasons like loading too much stuff.

When you turn it on, you have to call a lot of things. You want to look at the status of the process. alt+del+ctrl.

Notebooks are different from desktops, the internal accessories of the notebook are more precise, it is recommended that you use software to optimize the system, check and kill viruses, if you can't solve the problem, it's best to contact Dell customer service, don't disassemble the machine yourself.

There are a few reasons why your laptop's fan won't turn:

1. The fan is broken.

2. The fan shaft is rusty.

3. Motherboard reasons.

4. Too much dust accumulates inside the fan.

The laptop's fan is a dual heatpipe system, with a keyboard convection cooling fan. The rotation of the laptop fan is related to the CPU temperature, and the fan will only rotate when the CPU reaches the warning temperature, which means that the fan will rotate during CPU use. If the laptop's fan doesn't rotate, it is likely to cause the computer to restart, crash, and in severe cases, burn the CPU and some components.

Most laptops have achieved BIOS-level hardware power management, taking the CPU cooling fan as an example, unlike the fan on the desktop computer that rotates as soon as it is turned on, the laptop fan is only installed in the CPU position, and the fan is only started when the BIOS detects that the CPU temperature exceeds the manufacturer's preset value, so there is often a phenomenon of rotation and stopping, which is very normal, and some manufacturers' fans can even adjust the speed according to different temperatures, so as to reduce power consumption to a minimum. So if you have friends who encounter this situation, don't worry, it's normal.

1. If the laptop does not turn, you should first consider whether the fan is broken, and if it is broken, you can only take it for repair or replace one.

2. If the fan is normal and does not rotate, there may be three situations:

a.There is too much dust accumulating inside the fan. When cleaning, remove the fan from the heat sink, open the bottom oil seal, wipe them off with a cotton swab or paper, or use a wooden toothpick to slowly wipe off the dust.

b.The fan shaft is rusty. Take the fan apart and apply some pomade to the top of the hinge. Generally, dip a straw or tweezer into the lubricating oil, and drop a drop of lubricating oil in the shaft, not too much, and be sure not to use edible oil.

c.Motherboard reason. The less minor is only the damage to the power supply transistor, and the complex involves many components, such as the temperature control circuit.

If there is a fault in the relevant circuit during IBM notebook repair, for example, there is a problem with the temperature monitoring circuit of H8, a fan error error will be reported. At this time, it can only be sent to a professional repair shop.

Let's first understand the principle of laptop fans.

The laptop's fan is a dual heatpipe system and keyboard convection heat dissipation. Laptop fan. The rotation of the laptop fan is related to the CPU temperature, and the fan will rotate only when the CPU reaches the warning temperature, that is to say, the fan will rotate during the CPU use process.

If the laptop's fan doesn't rotate, it is likely to cause the computer to restart, freeze, and in severe cases, burn the CPU.

The workaround for laptop fans not turning.

1. If the laptop does not turn, first consider whether the fan has been broken, and if it is broken, it can only be repaired or replaced.

2. If the fan is normal, but the fan does not rotate, it may be that there is too much dust inside, and the user should clean it up in time. When cleaning, the heat sink and fan should be disassembled, and the heat sink and fan should be disassembled when cleaning.

3. The laptop fan hinge is rusty, and the solution is to disassemble the fan and apply some pomade oil to the hinge. Generally, dip a straw or tweezer into the lubricating oil, and drop a drop of lubricating oil in the shaft, not too much, do not use edible oil.

The fan is temperature controlled, and if the temperature is low, it will rotate very slowly. If it's abnormal and doesn't rotate, it is estimated that the fan is broken, so replace it with a new one.

CPU over-temperature protection, you can disassemble the machine, turn it to observe whether the fan blades are stuck, clean up the dust, the carbon brush of the motor is dirty, and the oil dripping can basically be solved, if it really doesn't work, then it can only be a worse fan.

If the ash is not sent for cleaning for a year, it may be that too much dust is deposited and the heat dissipation is poor. The fan overheated and went on strike. Remove the ash and add some oil. Small caseBecause my little y used to be the same. Hehe.

1. The fan usually turns on and turns, and after a while it will not rotate, if the machine temperature reaches a certain temperature due to a long period of use, or the CPU usage rate reaches more than 50%, the fan will rotate to dissipate heat.

2. The notebook has been used for more than 1 year, and there must be dust in the exhaust outlet of the fan, which will seriously affect the heat dissipation and cause the computer to overheat;

3. If the warranty period has passed, you can disassemble it yourself to see if the fan is broken, or send it for repair.

Normal, very normal, because Toshiba's fans are temperature-controlled, and when the temperature reaches it, it does not rotate when the temperature is not high. Previously, this technology was only used on laptops, but now it is also used on desktops. Notebook with this.

It is estimated that there is too much dust inside, so the fan can't rotate, so it is recommended to send it for repair.

Take it to after-sales maintenance, it should still be in the warranty period.

The fan is aging and broken, so send it for repair.

Can the laptop fan still work without turning? It's a cow.

It is possible that the laptop fan is not working because it is set.

There are two ways to do this:

Install some self-test software or configure system software for testing and setting, such as superpi, Master Lu, etc.

If it doesn't work, then you have to change the fan, since yours is a laptop, I don't guarantee that there are accessories to change, otherwise you will have to change the computer.

Hello! How many lines are your fans?

Maybe it can help you.

- Hurry up and get a fan! A CPU without a fan is absolutely a no-no! Now a good machine, as long as the fan does not turn, it can't be turned on directly!

If you do that, the CPU will be slower and slower, and it will get more and more stuck, how can there be a reason not to turn There are many reasons for not turning, find someone to take a special look.

Your computer has been used for a few years, if it is, then it is normal, you can take it apart yourself, look at the wiring, or give it to the Super Rabbit test to see.

Cause: The CPU usage rate is 100%, and the worm is generally infected. The high-speed operation of the fan means that the CPU usage is too high, and the heat generated is large, and the fan is running at high speed to dissipate heat.

The worm has remnants in other disks, so it still flares up after reinstalling the system. It is recommended to install the entire antivirus and reboot the system.

CPU100% It's obvious that the system you use Ghost is right.,This is caused by serious incompatibility.,For older computers,The data of the current Ghost system is relatively new.,The hardware data contained in the early shot is now more general.,The Ghost system has compatibility problems.,So the problem is more serious.,It is recommended to use the system disk of the Judgment Orthodox installation version to install the system。

QQ and QQ pets are meant to eat memory because of the product placement of Tengxunyu's virtual cover. Check which process in the task manager accounts for the CPU utilization, search the Internet for information related to the process, and solve the reputation.

What brand of machine configuration to say.
