You can find the cause of the noise your laptop is making.

A few weeks ago, one of my friends came to me with a problem, his phone charger was buzzing after the phone was fully charged.My main concern was that the charge may not be safe.I started digging because I had no experience with this kind of issue.You might be surprised to know that most phone and laptop charging points can make strange noises.

I would expect my laptop to make noise.I have a good idea of what I can do to stop it.If you are like me, you can't imagine which component is capable of making noise.We are about to figure that out.

I have never heard a charger make noise, so I wanted to know what it was like.The old cell phone chargers can make humming noises.You can hear those sounds in different videos.If you want to understand how I describe sounds, you can read up on onomatopoeia.

In the case of my friend's charger, the noise could be described as a buzzing or crackling sound.It was only after his phone reached full charge that it happened.That made me think of the problem of when the charge is making noise.It could be.

I think you should have the answers to several important questions if you end up taking your charger for repairs.You need to be able to describe the kind of noise the charger is making.You should know when the noise is occurring.It could be something I have not mentioned.

The laptop charger is slightly different.You would think that there are more things that can go wrong with them.Let's see how laptop and phone chargers are different.

The AC power adapter is where the two charging parts meet.Most of the components that could be making noise are inside the AC/DC power converter, which is the part that goes into the wall outlet.There are several parts to the laptop chargers.

A phone charger usually consists of a power source with a port and a cable.The component that goes into the power outlet is the one that transfers electricity to your phone.There are all the potential noisemakers further down the line.The two parts make noise because they serve the same function.

Some laptop chargers make sounds that are slightly different from the ones on the phone.The noise you hear at the beginning of the video can be described as groaning.I would say that the adapter is malfunctioning.A mix of electricity and crackling sounds is usually pretty good.

All electronics have the ability to make noise.You could say that most chargers make some kind of sound.They usually produce frequencies in a range above humans detection.I explained in my articles that our register is between 20 and 20,000 Herz.

The noise of electricity rushing through a power adaptor can be as high as 30,000 Hz.Can we hold the component inside the adaptor responsible for this offense?

There are several parts that convert AC power to DC power.The process begins with an inductor, rather than a transformer.The lower voltage power is converted to DC in a bridge rectifier.After a switch rapidly turns the power on and off, power goes through aCapacitor which evens the flow out before it leaves the house.

Most of these components can make noise.If the transformer is making a high-pitched sound, you can blame it.The component can start to vibrate when the electricity passes through it.You may have seen that sound on your old TV.

The other parts can make noise.Most switch circuits only produce high-frequency noises.When they are low enough to hear, you would notice a sound.What can you do about that?

We should answer some final questions before I dive into what you can do.Who would say you need to do anything?If the charger is still doing its job, why should you try to fix it?Should you be concerned about the buzzing sound?

Many people claim that their chargers have always been noisy.They work as you would expect them to.The excess noise is just one part of a bigger problem.You might have a fire hazard on your hands if your adapter is noisy and prone to overheating.

This isn't simply a problem with a simple solution.Most of the time, I would recommend that you use sound deadening material and be done with it.I can't recommend that you wrap your charger in vinyl if it's overheating.The heat will have a negative effect on the power adapter.

It may already be too late to fix the issue if your charger starts making noise.There is a way to find the cause of the noise and fix it.

First thing you need to do is make sure your charger isn't damaged.The most likely explanation is that it started making noise suddenly.People tend to let their chargers drag on the floor where they can get pulled and stepped on by anyone who happens upon them.

The full length of the cable should be checked.It will look different on phone and laptop chargers.You will only be looking for cracks and dents in the plastic, cut cords, and broken connectors.

If you notice one of those signs, you should skip to the last tip.

Some people have found a way to fix their noisy chargers by plugging them into another outlet.It wouldn't hurt if you tried it.If it turns out that the only issue was with an over or under powered outlet, so much the better.

Diagnostic tools can help you determine if a component is malfunctioning.HP has an AC Adapter Test that you can perform.

The laptop needs to be turned off and plugged in to work.Run the computer and press the Esc key until a menu appears.The HP PC Hardware Diagnostics main menu has component tests, power, and AC Adapter.Wait for the results when you press the Run once button in the following window.

Your options will depend on whether your device is still under warranty or not.If it is, you can take it to the company for repairs or replacements.If it isn't, you should still get a new one, but it will have to be on your own.

If you want to rule out all possible causes, you should check for fluctuations in the cord output.If there are any, it means that theCapacitor isn't doing a good job.You can check the voltage output with a voltmeter.If you get any of the measurements, they should be steady.

It is possible to do a wattage calculation to make sure that your charger suits your device.To run your laptop on the underside of the device, you will have to see the number of Volts and Amps.When you add those numbers up, you should get the power you need.

If you have a laptop that needs at least 2 Amps, you would need a 39 watt charger.You can go higher, but not lower.If you find a discrepancy, your best bet is to get another charge.

It is possible to get a completely new charge without needing a new one.If you don't know what you're doing, hand it over to professionals.A few things can be done by an amateur, such as replacing a part of the charger.

Most electronics stores have a good selection of cables and accessories.You should take care to get one that is compatible with your device, as they are easy to find online.

If you have to do more intricate work, give it to a more experienced person.It might be covered by your warranty.If it is, I would recommend buying a new one.Depending on the cost of repair services where you live, getting a new charger may be the most cost-effective option.

I only have one piece of advice for you if you decide to buy a new charger.Make sure you buy one from a reliable supplier.You can find the official storefront of the company you are looking at on Amazon.You don't want to be sidetracked by off-brand products.

An overwhelming majority of people experienced that issue with an off-brand charger while I was looking for resources.The products that overheated the most are those.

Hopefully, this article sheds some light on the different reasons why a charger might make noise.I think it comes down to age.When they are brand new, the kind of chargers we have don't usually make audible sounds.If your charger starts buzzing, you will know why.

You will also know how to stop it.You will probably have to pay for a replacement part or a new charge.I would sleep better if I knew that my phone charge wouldn't burn down my house.
