Why is the charger beeping? My smartphone charger makes a strange squeaking sound, is this normal? What to do with a beeping power supply

Power supplies are one of the most important and “capricious” components of modern technology, especially if it is a device such as a laptop, which is quite demanding on quality and cleanliness electric current and tension. In this article, we will consider those cases when it is worth paying closer attention to chargers in order to prevent failure of the entire device due to improper power supply.

There may be few breakdowns of the power supply. It either works normally, or charging begins to attract attention. This could be a power outage, which clearly indicates the need for repair or replacement, or an unnatural sound from the charger, audible to the naked ear.

Repairing modern chargers at home is a waste of time, and also completely voids the entire device’s warranty, since the units are often made in a monolithic case, which is impossible to open without leaving traces. Let's see why the squeaking occurs and whether it is possible and necessary to fight it.

Squeak from the power supply

Occurs due to action alternating current on parts of the block that are constantly under voltage with a frequency of 50 Hz. In a second, electricity manages to “run” along current-carrying parts 50 times and change their position, at least slightly. Accordingly, if the fastening of the parts is loosened, a squeaking sound will be heard, which, the more loose the part is, the louder it is.

Why is squeaking from charging dangerous?

Such sounds from the power supply do not always indicate its failure. The squeaking unit may well last for a long time, since essentially nothing is broken in it. Even service centers refuse to recognize the squeak as a breakdown, which is confirmed by legal standards. But you need to pay attention to this factor, especially when buying a new item that is still under warranty and which can be returned within 14 days. There are at least two reasons for this:

• It's just unpleasant. If you don’t pay attention to a slight squeak right away, then later it can become very annoying, especially since there is a possibility that it will intensify over time.
• There is a certain danger of failure of the charging itself. This is unlikely, but over time, if it is a manufacturing defect, then the vibrations of a loose part can loosen the soldering. In this place, resistance will arise, which, under the influence of electric current, will heat the entire area. At best, this will lead to deterioration in performance, and at worst, to short circuit and charging fire. Whether the laptop itself will survive in such an outcome is a matter of the reliability of the protection scheme and the attentiveness of the owner.

What to do with a beeping power supply

The conclusion is clear - tolerate this sound, or change the charge itself. Here pay attention to the operation of the device. If the power supply for the laptop beeps quietly, and the device itself is charging and functioning normally, then there is nothing dangerous. If there are power surges, then the only thing available at home is to try connecting the charger to another outlet, or in another building. If everything is the same, then get ready to lose a certain amount on a new device.

P.S. By the way, if, after repeatedly purchasing modern devices, you can almost always hear a squeak from the chargers, then there is a chance that your ears are capable of hearing a wider range of sounds than the average person.

The beeping sounds of the laptop charger indicate a number of malfunctions. The following article describes various reasons why your laptop charger may make beeping noises...

Charger- This is a mandatory device that comes with a laptop. The external power supply has a long cord that you can plug into your laptop to charge a dead battery. As you know, a laptop needs to be charged in order for it to work. Most laptop batteries are lithium ion batteries, so the powerful charge will have a negative effect on them and cause damage to the internal battery, also known as oxidation. Just like with other electronic devices, laptop chargers have also had problems. One of the most common problems is that the charger beeps and does not charge the laptop battery. This article identifies the causes of this problem and how to resolve them. So let's get started!

Why does my laptop charger beep?

Many laptop users complain that the charger does not work. They also say that instead of charging the laptop, the charger makes loud and prolonged beeping sounds that are simply annoying. The appearance of these sounds is caused by several reasons. Below are described possible reasons that can cause these beeping sounds:

Problems with the power supply

As we already know, the laptop charger runs on an external power supply. If there are problems with the external power supply, the charger starts beeping. This may be due to loose connections between the internal components of the laptop's external power supply. In this case, the charger may or may not make sounds.

Power problems

If there is a problem with the AC power you connect your laptop to, then it may cause problems with the charger and it will start making beeping sounds. The problem may be with the internal circuitry of the patch cord. Try plugging the charger into different outlets in your home to see if the charger is the problem or you are having an electrical problem.

Chain problems

If there is any problem with the electrical circuit, it may affect the operation of the laptop charger, causing it to start making beeping sounds. More often than not, if the battery terminals are connected together to an electrical conductor/wire with very low resistance, it will cause too much electrical current to be generated and the cell will supply too much electricity in a short time.

Problems with the production of the charger

Another reason why your laptop battery makes a squeaking sound is that you purchased a faulty charger. There is a possibility that you purchased a faulty charger with your laptop. This can happen to any brand and any manufacturer. Therefore, upon purchase, you must check the laptop battery and charger to identify any faults during the warranty period.

Solutions to the problem

Now that you know the possible reasons why your battery is not charging and your charger is making a beeping noise, you need to learn about ways to solve these problems. First of all, understand that when you are faced with such problems, there is only so much you can do. The only thing you can do is buy a new charger from the same manufacturer. If the problem is neither the electrical circuit nor the power supply, then all you can do is throw away the old charger and replace it with a new one. If the charger starts making beeping sounds during the warranty period, contact the retailer from whom you purchased the laptop. You can also contact the manufacturer's customer service department and request a replacement charger! These are the two best solutions.

A laptop charger is inexpensive compared to the laptop itself, and if your laptop's performance is at risk, then it's better to buy a new charger!

A normally operating charger should not make any sounds. Squeaking, noise and generally any sounds indicate a malfunction.

Why is my laptop charging beeping?

A squeaking sound when charging a laptop may be the result of exposure to alternating current on parts that are energized. A frequency of 50 Hz means that in one second the current manages to “bypass” the current-carrying parts 50 times and at least minimally change their position. Therefore, if the parts are not secured sufficiently, sound will be heard from the unit. The more loose the part is, the louder the sound will be.

Another reason why laptop charging is noisy could be problems with the electrical circuit. If the laptop battery terminals are connected to a conductor with low resistance, too much current may be generated and the cell will supply too much energy in a short period of time.

Finally, the charger may squeak due to a banal defect made by the manufacturer. No electronics buyer is immune from this, so even when purchasing a computer, you should check how well the laptop’s battery and charger are working in order to avoid problems in the future.

Is a beeping charger dangerous?

Sounds coming from a laptop charger do not mean that the unit is faulty. The beeping device can last for years, since, by and large, there are no violations in it. The best proof that squeaking is not the biggest problem is the refusal service centers Consider sounds from the charger as a breakdown. Thus, answering the question “why is the laptop charging beeping,” there can only be two significant problems with the laptop charger:

• it’s just not very pleasant, especially since there is a possibility of increased noise;
• albeit low, there is a possibility of charging failure with all that it entails, from deterioration in performance to fire of the device.

There is only one conclusion: a squeaking power supply is not the most serious problem, which, even if the owner does not act, does not promise big trouble. If the charging sound is not annoying or distracting, it can be tolerated. Otherwise, you will have to spend money on a new device. And there is certainly no point in trying to repair a laptop charger at home.

Owners of new or old tablet computers often encounter a problem when the used mobile device makes a quiet or loud, periodic or constant squeaking sound while performing various actions. You can find out why the tablet beeps after examining the device. Only a technician can give a final answer after diagnosing the “machine,” but experienced users can outline the preliminary cause of what is happening.

Why the tablet beeps: problems and solutions

Experts say that the characteristic quiet squeaking sound, almost imperceptible to humans, is always present. This is the norm. You can hear it in complete silence by placing your ear to the body of the device. If the sounds are persistent, occur constantly or periodically, under load, while working in safe mode, each individual case should be dealt with.

The methods below can help in cases where the device does not charge at all, the device charges every other time, does not charge at all, and also in cases where when connecting/disconnecting the charger the phone/tablet behaves incorrectly (reboots/turns off, signals that it continues to charge in similar cases). In addition to the above methods, you can try to carefully bend the contacts upward (towards the display), it is quite possible that the problem is due to poor contact of the charger with the connector.

If nothing helps, then most likely the problem may be in the battery, usb connector or controller, in which case you need to try replacing them one by one (links to relevant topics on this issue are under the spoiler...

Pipe L9, the original charger burned out after buying the phone due to a voltage drop. Euroset sold the original charger for L7, they said it would be suitable. Such a problem, you insert the charger into the socket - nothing beeps, connect the cable of the device to the phone - a beeping starts. Charging proceeds as usual, but with this squeak. This is problem? why this squeak?
I also noticed that with inactive use, without multimedia capabilities, only infrequent calls - charging lasts for 2 days maximum. When you start listening to the radio, the battery quickly drains. Is this the case for everyone or should we go to Euroset to figure it out?

I had this too, but after moving to a new apartment it all went away!!!

Re: [poll] is your phone charger beeping?

>Maybe I'm a loser, but not only does my Nokia charger beep, but my PC also squeaks when it's turned off and charging. The same squeak as from the charger. >The logitech lx5 wireless mouse also makes a similar sound.

Yeah, almost any electronic device beeps. By changing the tone and modulation, you can even guess without looking what it is doing at a particular moment. This background is present in almost any room, but if it is not highlighted, it is invisible.

PS Soviet ultrasonic devices are just p....ts - at a distance of 3 meters the ears already curl up into a tube and try to fall off.
