Beeps on the phone charger and does not charge. The smartphone charger makes a strange squeak, is this normal? ... while charging

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

There may be little damage to the power supply. It either works fine, or charging begins to draw attention to itself. It can be either 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, as well as one hundred percent removal of the entire device from the warranty, since the blocks are often made in a monolithic case, which cannot be opened without traces. Let's see why there is a squeak and whether there is a possibility and a need to fight it.

Squeak from the power supply

It occurs due to the action of alternating current on the parts of the unit, which are constantly under voltage at a frequency of 50 Hz. For a second, electricity has time to "run" 50 times over the current-carrying parts and, at least a little, but change their position. Accordingly, if the fastening of the parts is loosened, then a squeaking sound will be heard, which, the more the part is loosened, the louder it is.

What is the danger of squeaking from charging

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

It's just unpleasant. If you do not pay attention to a slight squeak right away, then later it can start to annoy very much, especially since there is a possibility of its intensification over time.
There is a certain risk of failure of the charging itself. This is unlikely, but over time, if it is a factory defect, then the vibrations of the loose part can loosen the soldering. At this point, resistance will arise, which, under the action of an electric current, will heat the entire area. In the best case, this will lead to a deterioration in performance, and in the worst case, to a short circuit and a fire in the charging. Whether the laptop itself will survive with such an ending is a matter of the reliability of the protection scheme and the attentiveness of the owner.

What to do with the beeping power supply

The conclusion is unambiguous - to endure this sound, or to change the charging 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 that is 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 repeated purchases of modern devices, you can almost always hear a squeak from charging, then there is a possibility that your ears are able to hear a wider range of sounds than that of an ordinary person.

First of all, think about this: imagine that your father / son / brother has an appendicitis pain and you know from the symptoms that it is just appendicitis, but there is no experience of cutting it out, as well as the tool. And you turn on your computer, access the Internet on a medical site with the question: "Help cut out appendicitis." Do you understand the absurdity of the whole situation? Even if they answer you, it is worth considering factors such as the presence of diabetes in the patient, allergies to anesthesia and other medical nuances. I think no one does this in real life and will risk trusting the life of their loved ones with advice from the Internet.

Owners new or old tablet computers often encounter a problem when the used mobile device makes a soft or loud, intermittent or constant squeaking sound in the process of performing various actions. You can find out why the tablet beeps after reviewing the device. The final answer can only be given by the wizard after diagnosing the "machine", while experienced users can give an outline of the preliminary reason for what is happening.

Why the tablet beeps: problems and solutions

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

Why is the laptop power supply beeping

Pipe L9, native charging burned out after buying a phone from a voltage drop. In Euroset, they sold the original charger for the L7, they said it would do. Such a troubleshooter, you plug the charger into the socket - nothing beeps, you connect the device cable to the phone - a squeak starts. Charging goes on as usual, but with this squeak. This is problem? why is this squeak?
I also noticed that with inactive use, without multimedia capabilities, some infrequent calls - charging is enough for a maximum of 2 days. You start listening to the radio - the battery very quickly sits down. Is it all for everyone or is it still to go to understand the Euroset?

I also had this, but after moving to a new apartment everything went away !!!

Re: [poll] and your phone charger beeps?

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. In almost any room, this background is present, but if it is not highlighted, it is invisible.

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

The charger is a must-have device that comes with your laptop. The external power supply has a long cord that can be plugged into a laptop to charge a depleted 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 high charge acts negatively on them and causes damage to the internal battery, also known as oxidation. As with other electronic devices, laptop chargers also had problems. One of the most common problems is the charger beeps and won't charge the laptop battery. This article lists the causes of this problem and how to fix them. So let's get started!

Why is my laptop charger beeping?

Many laptop users complain that the charger is not working. They also say that instead of charging the laptop, the charger makes loud and lingering squeaking sounds that are just annoying. There are several reasons for these sounds. Described below possible reasons that can lead to these squeaking sounds:

Power supply problems

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

Power problems

If there are problems with the AC power source you are connecting your laptop to, they can 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 problem is with the charger or if you're having electrical problems.

Chain problems

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

Problems with the manufacture of the charger

Another reason the laptop battery makes beeping sounds is because you purchased a faulty charger. It is possible that you purchased a faulty charger with your laptop. This can happen with any brand and any manufacturer. Therefore, it is necessary to check the laptop battery and charger at the time of purchase in order to identify any faults during the warranty period.

Solutions to the problem

Now that you know the possible reasons why the battery will not charge and the charger makes beeping sounds, you need to learn about ways to solve these problems. First and foremost, understand that when you face these kinds of problems, there is not much you can do. The only thing you can do is buy a new charger from the same manufacturer. If the problem is not the electrical circuit or 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, please contact the dealer from whom you purchased the laptop. Alternatively, you can 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 stake, it's best to buy a new charger!

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

Why is laptop charging peaking?

Squeaking squeaks in laptop charging may be the result of AC power on live parts. The frequency of 50 Hz means that the current in one second manages to "bypass" the current-carrying parts 50 times and at least change their position at least minimally. Therefore, if the parts are not secured enough, sound will be heard from the unit. The more the part is loosened, the stronger the sound will be.

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

Finally, the charging can beep due to a banal marriage admitted by the manufacturer. Not a single buyer of electronics is insured against this, so even when buying a computer, you should check how well the laptop battery and charger are working in order to avoid problems in the future.

Is squeaking charging dangerous?

Sounds coming from the laptop charger do not mean that the unit is out of order. A beaker can last for years, as it is largely free of any irregularities. The best proof that the squeak is not the best a big problem, can be considered a refusal service centers Consider sounds from charging a breakdown. Thus, answering the question "why the laptop charging beeps", there can be only two significant problems with the laptop charger:

it is simply not very pleasant, especially since there is a possibility of noise amplification;
albeit low, but there is a possibility of charging failure with all the consequences, starting with deterioration in performance and ending with the fire of the device.

There is only one conclusion: the squeaking power supply is not the most serious problem, which, even if the owner is inactive, does not bode well. As long as 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.
