How to solve the noise in the Dell notebook?

Dell notebook from the overall performance of it is slightly higher, but it is assembled by other companies OEM this kind of software, Dell correspondingly this notebook if there are some volume noise problems, the main reason is that the quality of the speaker he uses is relatively not very good, and there is also a problem that when you use the notebook, there are some electromagnetic magnetic fields around you that are easy to reduce, destroying the electromagnetic induction of this speaker speaker, The sound of it will change a little, so the best thing to do at this time is to replace it with a new speaker.

If there is noise in the external sound of the notebook, one situation may be that there is a problem with the external speaker and needs to be repaired, and there is another situation that his driver has a problem and can re-drive the sound card.

It is recommended that you go to the after-sales service of your local Dell computer to check what is the best problem, and then prescribe the right medicine to solve the problem.

I hope mine can help you, hope, thank you.

First of all, you need to confirm what is causing the noise, for example, it is the movement of the hard disk or the fan, or other current sounds, you need to confirm what is causing the sound to solve the problem, in fact, the best thing is to take it to the maintenance and sale to let others confirm it.

Laptop murmurs include many kinds:

Shanghai Notebook Repair Center 400-669-99651, the sound of hard disk head sliding may cause damage to the hard disk.

2. The current sound (which can be clearly heard by the power adapter) needs to go to the after-sales center to detect whether the power accessories and battery are faulty.

3. When the cooling fan rings, check whether the cooling device is faulty, so as to avoid damage to the motherboard caused by heat dissipation failure.

4. If you can't determine that it is the first sound, you need to go to the after-sales center for testing and processing.

It should be a problem with the optical drive, enter the BIOS settings, and the optical drive will not automatically start when it is turned on.

The sound of disk reading and writing, or the sound of electric current, is a phenomenon that is common in notebooks today, as long as it does not affect your normal use and there is no functional impairment.

Detailed steps to resolve the computer with noise, cracking, or no sound.

Is there a problem with the files you put in? Some songs have a bit rate that is not very high, and this kind of noise will occur, or it may be that the tone of the song is too high, exceeding the limit of the sound of the sound and causing a broken sound, or the bass is too heavy when the **file is recorded.

There are a number of things that can cause a computer speaker to be noisy

1. 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.

2. Mechanical noise is unique to active speakers. 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. 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 wear, 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**.

3. 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.

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!
