What is the reason for the sound of a laptop?

It is mostly the noise caused by the operation of the fan, the failure caused by more dust and more shaft mud, generally do a deep cleaning and maintenance, there are three steps to disassemble and clean the fan, one is to clean the ash, the second is to add lubricating oil to the fan, and the third is to replace the heat dissipation grease. Notebook hardware questions answered.

There are several possibilities for loud sounds:

1.After using it for too long, the coil of the fan is aging and lacks oil.

2.The bottom bracket is bent due to improper use, impact or vibration.

3.Excessive fan dust accumulation or loose set screws cause the position to shift.

4.Power supply issues.

What should I do if my laptop fan is loud? Loud solution:

Disassemble it yourself,I can tell you simply,First pry open the place with the interface on the top of the keyboard,Then disassemble all the screws underneath,Take down the keyboard first,Then take off the optical drive from the rear,Take off the hard disk,You can disassemble it to see the cooling fan,You will know what the problem is。 At present, in order to consider the cost, HP's machines do not pay attention to consumer customers at all. The fan is loud, if the machine is on for two years it is the fan has dust.

If the new machine can't be heated, the fan is turning with the temperature of the machine, and the sound should be the sound of the hard disk.

There is a small problem, the fan is short of oil. Go to after-sales within the warranty, and buy sewing machine oil outside the warranty. A bottle for a dollar.

Go to the Internet and search for how to open a notebook. I've been on it several times, and it's good to finish it, and occasionally I use peanut oil, mainly for lubrication. Oil the fan shaft with the groove attached to the coil, and then install the small bubble after oiling.

After-sales at least 150 or more, but I'm not sure I'd better find someone to fix it.

Another possibility is that the fan is dirty or damaged, mostly dirty, send it for repair and dismantling to clean it up, and it will be fine, if it doesn't work, you need to replace the fan, and you can repair it on the same day. It is recommended that you find a reputable and skilled repairer to help you with the repair. Don't panic if the laptop fan is loud, the above method believes that it can solve the problem of what to do if the laptop fan is loud.

One of the reasons that could be the fan, and the other reason is the sound of the hard drive, and it's best to clean up the dust, so that at least the fan doesn't spin wildly.

It has to do with the power supply and voltage, see if it's a fan problem.

Wouldn't it be good for me to turn the volume down or turn it off?

The noise becomes louder during the operation of the notebook, because there are hard disks and cooling fans and other devices inside the notebook, due to its mechanical structure, it will produce a certain amount of noise during high-speed rotation, so it is normal to have a certain amount of noise. If the laptop is too noisy, it is recommended to do the following:

1. Raise the bottom of the notebook or add a heat dissipation base to keep ventilation smooth;

2. Upgrade the anti-virus software of the machine for overall anti-virus.

3. Turn off the startup items that are not commonly used.

4. Check whether there are foreign objects at the fan that cause the fan sound to increase;

5. If the battery can be taken off, then it is recommended to shut down, remove the external power supply and battery, as well as all external equipment, stand for half an hour, release the static electricity, and connect the adapter after half an hour to boot the test;

6. If it is not easy to use, it is recommended to back up the data and reinstall the system. If the problem persists, or if you confirm that there is no problem with the system, it is recommended to contact your local service center to investigate the specific cause, such as whether you need to clean up the dust and detect where the sound is coming from, and then deal with it.

The reasons for the loud buzzing of your laptop are as follows:

1. Power supply fan. If the computer will have a buzzing sound when it is turned on, you may wish to turn off the computer first, and then use a screwdriver or pencil to insert it into the vent of the power supply fan in the shutdown state, and then turn it on after holding the fan, if the hum still exists, it proves that there is no problem with the power supply fan, and if the hum disappears, it proves that it is caused by the problem of the power supply fan (it should be noted that when shutting down or booting up the test, the time should not be too long, and after testing the fan sound, you should immediately pull out the screwdriver or pencil-shaped object).

In this case, it is best to find a computer company to help replace it, because you need to disassemble the power supply, and then cut the fan line, and connect the external power supply additionally.

2. Motherboard fan. There are two kinds of motherboard (CPU) fans, one is AMD's, AMD's can be held down with your fingers, but if it is an Intel fan, you must use a screwdriver or pencil-like object to pin the fan in the shutdown state, and then turn it on, if the sound is still there, the problem of the motherboard fan is ruled out, if the sound disappears, it proves that it is a problem with the motherboard (CPU) fan, you can directly buy a universal fan to replace it, if the user will not replace it, you can go directly to the computer company to replace it. 3. Graphics card fan.

The three most common fans in a computer case are the power supply fan, the motherboard (CPU) fan, and the graphics card fan.

Laptop.

Possible reasons for the high boot sound:

1) The vibration of the fan generally needs to be disassembled and cleaned by the fan shaft for cleaning.

2) There is a lot of computer dust, 3) due to the lack of oil and dryness, the fan starts with a large torque, and the noise is large, and the torque is small after the speed is normal, and the noise is reduced.

The laptop fan is the most important accessory part of the cooling system of the laptop, because it also has a chip, which is different from the desktop fan. The problem of heat dissipation has always been a problem in notebook design, and with the continuous improvement of the configuration of this notebook, it is undoubtedly a huge test for the thermal system of this notebook.

If the heat is not evacuated in time, the notebook will work at high temperatures for a long time, which will cause the notebook to crash, system crash, and sudden power failure, and accelerate the aging and scrapping of the notebook or even burn the hardware. Therefore, it is a big problem that users of this notebook cannot ignore to let the notebook generate as little heat as possible or let the heat generated by the notebook dissipate and conduct it in a timely and effective manner.

When the fan is working, it will produce a certain sound due to the rotation of the fan and the flow of air, which is a normal phenomenon. The rotation of the fan is related to the temperature of the CPU, such as the use of high ambient temperature, too many running programs or large software will cause the CPU temperature to rise, when the CPU temperature increases, the fan will rotate more frequently, and the sound will be louder. If the sound is particularly loud or you feel that it is abnormal, it is recommended to go to the nearest official service center to test and confirm, and it is better for the engineer to test it on site.
