Is it normal for a newly bought laptop to have a buzzing sound

If there is a noise in the laptop, it may be that the internal hard drive or fan is running.

When the hard disk is working, it will emit a certain sound due to the high-speed rotation of the motor and the movement of the magnetic head. When your hard disk reads and writes frequently (power on, boot program, defragmentation, antivirus, etc.) or when you are in a relatively quiet environment, the sound of the hard disk will be slightly more obvious, and it should be more convenient to observe that the noise and the hard disk indicator are synchronized, which is a normal performance.

It is normal for the laptop's fan to produce a certain sound when it is working because of the rotation of the fan and the flow of air. 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 abnormal, it is recommended that you go to the nearest official service center to test and confirm, because ** can not confirm the specific sound, it is better for the engineer to test it on site.

This sound is common.

Hard disk, the sound of the fan, the specific reason needs to go to the local after-sales service to confirm.

First, if the sound is continuous and regular, it is generally more likely to be the sound of the fan.

You can take a look. Whether the fan is at high speed when abnormal noise, if the fan is at low speed, it is generally due to the failure of the fan itself and the fan needs to be replaced.

If the fan is always running at high speed caused by abnormal noise, if the CPU temperature.

Normal, that means that the fan temperature control is faulty, and this situation needs to be repaired.

If the CPU temperature is always high, this situation is mostly because there is too much dust on the fan radiator, which affects the heat dissipation.

Second, if the sound is intermittent and irregular, it is generally a mechanical hard disk.

The sound that is made.

The mechanical hard disk will emit a certain sound in response to the high-speed rotation of the motor and the movement of the magnetic head, and the noise performance of different models will be different due to the difference in the specifications of the hard disk used and the difference in the installation position of the hard disk, in the same environment.

When your hard disk reads and writes frequently (power on, boot program, defragmentation, antivirus, etc.) or when you are in a relatively quiet environment, the sound of the hard disk will be slightly more obvious, and it should be more convenient to observe that the noise and the hard disk indicator are synchronized, which is a normal performance.

If the sound is too loud, it is recommended to go to the after-sales test.

It's not normal to be loud.

The hard drive will vibrate slightly.

The fan will turn sharply when it starts.

There is a sound. It's best to go to the merchant and compare it with the new machine.

1. The sound of the fan is buzzing all the time, and the sound volume is stable, because the noise generated by the dust or the fan bearing has no oil after long-term work, it needs to be disassembled (cleaning the ash or replacing the fan).

The latter two are generally normal.

Second, there is a buzzing sound, and the sound volume is always the same, which is the sound of the hard disk (generally not loud).

3. If the fan is from small to large, and from large to small, it is the sound of the CPU fan (if such a sound becomes abnormally loud, it is also caused by dust, etc.).

If the high temperature continues, then it may be that there are a large number of programs running in the background of the computer, resulting in the CPU running at high speed, and the fan must be maintained at a large wind speed to achieve the purpose of heat dissipation2If the cooling fan is damaged, the fan will gradually wear out after a long period of use, or due to the lack of oil in the bearings, the fan will make a loud noise when it rotates. Moreover, due to the low degree of fineness of workmanship, the center of gravity of the fan blades deviates from the fan blades, which will cause the fan to be abnormal.3

After the computer is used for a long time, a large amount of dust will accumulate on the fan blades, which will increase the load of the fan and reduce the speed.

Hope it helps.

Here's how to fix laptop buzzing:

1. CPU and graphics card are the key accessories of the computer, their heat dissipation is very important, the best way is to strengthen the heat dissipation capacity of the heat sink, so that the fan is always in a low speed state. Regularly scraping off the aged silicone grease and reapplying it with a new one, or replacing it with a silent cooler with better heat dissipation performance can help reduce hum noise.

2. When the mobile hard disk or optical drive is working, it vibrates and emits sound, and no special treatment is required.

3. Sometimes the hard disk data cable or power cable will touch the fan of the CPU or graphics card, so comb the internal cables of the host to make it neatly placed, and try not to touch the fan.
