What should I do if my ASUS laptop is noisy?

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 that it is 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 to have an engineer to test it on site.

First of all, I analyze the causes of the noise: the mobile phone is placed next to the computer, and there is information for a few days, and the wireless connection for the laptop has always had signal interference, and the computer will make a squeaky sound, which will interfere for a few days. The computer starts to have noise, and if you put on headphones, there will be noise in the headphones.

Ask the master, how to solve this kind of problem, the computer has been bought for two years, the warranty is estimated to have passed, and the place where I bought it is a little far. Can you solve it yourself?

Concern. There are many situations that will cause noise in the computer audio, such as the speaker is interfered with, the interface or connection line is not in good contact, and the sound itself is of poor quality.

Generally speaking, computer audio is mostly active speakers, and there will be amplifiers inside, so noise is inevitable, and the noise of active speakers can be roughly divided into electromagnetic interference, mechanical noise and thermal noise.

Electromagnetic interference can be mainly divided into power transformer interference and stray electromagnetic wave interference. Generally speaking, the power transformer interference is caused by the power flux leakage of the multi-speaker speaker, and the effect of installing a shielding cover for the transformer is very obvious when conditions permit, which can block the magnetic leakage to the greatest extent, and the shielding cover can only be made of iron materials. We should try to choose products with big brands and solid materials, and in addition, using external transformers is also a good solution.

Stray electromagnetic interference is common, and speaker wires, crossovers, wireless devices, or computer hosts can all become sources of interference. Keep the main speaker as far away from the computer as possible and reduce the number of peripheral wireless devices.

Mechanical noise is specific to active loudspeakers. During the operation of the power transformer, the core vibration caused by the alternating magnetic field will produce a mechanical noise, which is very similar to the humming sound emitted by the ballast of a fluorescent lamp. Choosing the best product is still the best way to prevent this noise.

In addition, we can add a rubber shock absorber between the transformer and the fixing plate.

It should also be noted that if the potentiometer is used for a long time, the contact between the metal brush and the diaphragm will be poor due to dust accumulation and abrasion, and noise will be generated when it rotates. If the screws of the speaker are not tightened, and the inverter is not handled properly, mechanical noise will also be generated when the **big dynamic**.

This thermal noise can be dealt with by replacing low-noise components or reducing the working load of the components, and reducing the operating temperature is also one of the most effective methods.

In addition, some computer speakers, when the volume is turned up too much, there will also be noise. This situation is caused by the fact that the output power of the power amplifier may be small, and it cannot avoid the large dynamic peak signal at the moment, or because of the overload distortion of the horn.

Most of the murmurs come from:

1.The quality of the power supply is not good, resulting in AC interference in series;

2.Some laptop fans with CPU fans are faulty;

3.hard disk operating noise;

4.Poor motherboard filtering performance (poor manufacturing process);

5.Poor heat dissipation leads to deterioration of hardware device performance;

6.The laptop's built-in sound card integration performance is poor.

Resolved:1Don't put **, turn the volume to the maximum sound, the speaker has a "buzzing sound", indicating that the AC interference is serious, unplug the power supply, and the interference also indicates that the performance of the motherboard hardware equipment is declining; If the interference disappears, it is a power failure;

2.Replace the CPU fan and remove the dust;

3.Hard disk noise cannot be eliminated, only replaced;

4.Repair or replacement of motherboard failure;

5.To solve the heat dissipation, you can install a base fan to try it;

6.The integrated sound card fails only by replacing the motherboard or repairing.

What should I do if my laptop has noise? The sound quality of the computer is an important reference for many users when choosing a computer, and the sound quality is particularly important when watching videos or listening to songs. However, recently, many netizens have mentioned the problem of noise in the notebook, what is the reason?

What should I do? Let me tell you about it.

Daquan One:

1. Check whether the speaker is disturbed

If there is a mobile phone near the computer speaker, or other high-power transmitters, it may cause the computer to have noise, such as when the mobile phone calls, the speaker has a "whoosh" sound, at this time, just take away the interference source.

Second, check the dust accumulation of the speaker

Check whether the speaker has been used for a long time, and whether there is a lot of dust around the sounder, which may also cause the core inside the speaker to vibrate and make a "buzzing" sound. Therefore, it is recommended that you can clean up the speaker and tighten the screws that fix the iron core in the speaker, which can solve this problem.

3. The computer temperature is too high

In high temperatures, it may also make noise if you use the computer for too long. At this time, you can lower the working temperature of the speaker or laptop, or let the computer take a break at the right time.

Many times, when it comes to sound quality problems, everyone will think that the speaker is disturbed, not really broken, so there is no need to replace the speaker directly. According to the method I mentioned above, check step by step, and I believe that it can be solved in the end.

Daquan II:

1.Start Control Panel Sound & Audio Devices Advanced, then open the dialog box and click on "Options" and then click on Properties. In the selection"conexant hd audio output"For this item, except for the microphone input volume", all others are checked.

2.Before disassembling the notebook, be sure to wash your hands and discharge your own static electricity to avoid harming the internal electronic components, then cut off the power supply of the notebook, take off the battery, find a suitable screwdriver to prepare for disassembly, and remove the cleaned part of the shell. There is a lot of dust gathered on the air outlet, and it is best to remove the heat dissipation components to clean up, but it is more troublesome to apply silicone to the CPU and chip set from the new, and some machines have not yet passed the warranty period, so the removal will lose the warranty, so we can use a brush to gently stick away the large dust, and repeatedly blow off the dust on the surface with an air blower.

3.If this is not possible, refill the system or go to the maintenance station for repair.

Summary

The above is my recommended introduction to the treatment of noise on the laptop, I hope it will help you!

Why does a laptop have a murmur

A noise on your laptop may be caused by a broken speaker or a change in speaker settings, or it may be due to excessive dust gathering inside the body. So you can solve this problem very well with the method I recommended above, go and try it without spending your money!
