Laptops do not sound completely silent. Different components produce various sounds when it’s working. But, generally speaking, a good laptop won’t produce a buzzing click or humming sound.
Your laptop shouldn’t sound as loud until you’re unable to use it comfortably. When you are doing CPU-intensive tasks like gaming or editing, you might hear the sound of the laptop’s fans. However, it’s not so loud that it makes you feel uncomfortable.
In this article, you’ll learn about some solutions to help you to Fix Laptop Makes Noise When Plugged In. If you find that your laptop is making an eerie whirring or grinding sound when you plug in the power adapter, this could signify a more serious issue.
However, it is important not to be too quick to conclude that you have damage to your hardware and don’t be a panicker immediately. Instead, try to debug the issue step-by-step and help to find a solution.
Fix Laptop Makes Noise When Plugged In
What causes laptops to make a sound when it is connected?
1. The sound generated by your laptop right after plugging in the charger suggests that it is an HDD or speaker issue. It could be the fan is running at full speed, too. In the worst scenario, the laptop’s motherboard could be damaged internally.
2. If the fan is rattling, then it could be because of the cooling profile of the device when it is it is plugged in. It is likely to be different. When the battery is powered, the fan can’t go fully speedy, but it does spin at maximum speed when connected to the battery.
3. It could be due to dust that has clogged your laptop’s fan, which prevents them from cooling. It could also be due to a defective charger or faulty internal hardware.
4. In general, if you hear a rumble when you plug in the power adapter is connected, it could mean that your charger is suffering some type of damage, or your laptop’s battery could not work properly. In the worst-case scenario, a portion of the laptop’s motherboard is failing, which is preventing it from providing sufficient power to the parts.
Because the reason for the issue is inconclusive, it’s suggested to thoroughly test your laptop (both on the software and physical level) and then try to pinpoint the root cause.
The next part of this blog post will explain how to handle a situation where your laptop is making noises when connected.

What do you do when your computer starts making noise when connected?
If you’re experiencing the sound immediately after connecting your power adapter, you can try the steps below to solve the issue.
- Unplug from the Laptop battery and test whether that helps
- Try using a different AC adapter (Voltage and Ampere should be inline)
- Removing/replacing Hard Drive
- Check your laptop fans
- Check your laptop speakers
- Try the new motherboard
Make sure you follow the steps below in detail:
Step 1: Disconnect the laptop battery and check how it performs
If your laptop is making noise when connected, you must first take out the battery or unplug it from the motherboard. Connect the power adapter to the motherboard and switch off your computer. Nevertheless, If the buzzing sound disappears after removing/disconnecting the battery, you should not be convinced that the battery is malfunctioning.
In addition to the laptop battery, the charging circuit may be faulty, which could cause a buzzing or grinding sound!
You’ll need to change the battery and check whether that can stop the sound. However, make sure you purchase an appropriate battery that matches the profile of your laptop. In reality, changing your battery can be the best method to determine if it’s creating the noise when it is on.
If replacing the battery doesn’t solve the problem, it’s time for you to test the charging circuit and then modify it if it’s not working (if it’s not a component that is part of your motherboard). An integrated charging circuit means it is possible to replace the laptop’s motherboard, which you can learn more about below.
In both instances, don’t forget to inform your dealer or the company when your product is within the warranty.
Step 2: Test an alternate AC adapter (Voltage and Ampere should correspond)
It’s possible that your AC adapter has suffered some kind of damage, and your laptop starts making noises when you plug into that cable. Laptop chargers are often damaged because of poor positioning, overstretching, broken, or tripped over by objects or people, which could cause the proper flow of current to your laptop and cause odd sounds to come out.
A small number of damages to the circuit board in the adapter can prevent the correct, current conversion of the home current, which is vital for the laptop. The uncontrolled ampere could damage your laptop’s internal components and cause odd noises when it is plugged in.
To debug your charger:
- Then, change it and then see if that resolves the noise issue.
- Then, connect the charger to the outlet after some time, and then examine the charger brick to determine if it’s getting hotter or not (it should become hotter in its current flow).
- Third, you can use a voltmeter to determine your charger’s output. If you notice any more fluctuating reading than the stated output on your laptop’s info, this could indicate a damaged charger cable.
If your laptop is under warranty, you must contact the company to inquire about an opportunity to replace it. If a warranty does not cover a laptop, owners can purchase a new adapter through online retailers or are listed on the manufacturer’s official page.
The majority of adapters are marked by watts that can be determined by multiplying amps and voltage. For instance, 21V and 5A provide the 105W power required for healthy working.
Step 3: Removing/replacing Hard Drive
If your laptop comes with mechanical hard drives, as many budget laptops nowadays, it could be the source of the noise coming from your laptop. HDDs, unlike SSDs, are composed of moving parts that spin at a rapid speed to read data on the drive.
If you are carrying your laptop even when it’s operating, you must be aware that it slows down the destruction of your hard drive’s lifespan. External forces to your HDD could result in it scratching the head of the HDD to scratch your platter’s magnetic surface. This is among the most frequent causes of a hummed mechanical hard disk drive.
It’s also possible there is a possibility that the power supply cable to the HDD is damaged, and with the insufficient flow of current, the HDD could make strange noises.
It’s difficult to tell if it’s the power supply cable of the HDD or the power supply cable for your HDD until you try an additional Hard drive using the identical cable. If the sound is still present on the new hard drive, you must change the cable for power and check the status.
Unfortunately, replacing the HDD/power supply cable can be the best way to verify if the cables are why your laptop is making noises when connected.
This is only applicable if you realize that you’re dealing with only the HDD area of your laptop producing the noise. You can inform the company regarding the HDD/power cable if your item is in warranty.
Step 4: Check your laptop fans
This “Laptop creates noise when it’s connected” the fan could cause issue. Fans can produce an eerie clicking or buzzing sound for various reasons. Laptops’ position and damaged fan blades could create these strange noises.
It’s possible that when you plug in an external power source into the model, the fan’s settings may be set to maximum speed, and operating at maximum speed isn’t optimal for the lifespan of the fan. An unreliable fan could cause this kind of noise, but it doesn’t need your laptop to be the one in charge. In general, noise from fans is expected from laptops so long that it’s not a click or grinding sound.
If your laptop is excessively hot due to external power, and fans can’t push the hot air from your laptop, you must make sure that your fans aren’t blocked by dust. Monitoring the status of your fan is within your reach, so you can ensure that your fans are operating properly.
Put your ear on the exhausts on your laptop and determine whether the noise is coming from the fan. Then, use a flashlight to illuminate the vents to see for vibrations in the blades or a broken part.
It’s more effective if you could determine your fan’s condition by looking inside. Look up ” How to open your laptop’s name and password“, and you’ll be able to find helpful instructions for opening your laptop. You can manually rotate the fan, and if the fans have been damaged, you may request the replacement they are under warranty or bring it into the centre for repair.
Tip Use coolers to aid the fans to cool the PC more effectively.
How do I change the laptop’s cooling profile when charging?
- Look up “edit power plan” and then open the window for power management.
- Simply click on ” Change advanced power settings”.
- The “Power option” window will pop up “power option” window will open and expand to show ” processor power management” settings.
- Expand your ” System cooling policy” and ensure that the “plugged to” profile is active.
If the device is connected technically, there is no way to cool passively. Since the processor will begin to heat up when the threshold for safety is reached, the fan will begin to run at full speed.
Step 5: Check your laptop speakers
When speakers age and components of the assembly may become damaged. Speakers are often the first to check if you detect an unsettling static sound on your computer. However, we tend to overlook it as the main cause of the issue.
Concerning speaker problems, noise is a factor. It is a possible software or hardware issue. However, if your laptop produces a noise when connected, it
Nearly eliminates the software issue here.
The most efficient method of testing the speakers is removing the driver and using an audio headphone as the source of audio output. If the sound comes out of the laptop, the speakers are in good condition.
In the reverse direction, bring your laptop to the repair centre to test it using new speakers when the external power adapter is connected.
Test the brand new motherboard
It’s costly. However, laptops often make sounds like a buzz if your motherboard has sustained damage. It is difficult to pinpoint what part of the motherboard is the cause, but you must take it to a repair facility for further examination.
Connect with your local tech support or a computer repair centre for additional assistance. The nearest centre is on Google map as well.
This is my personal experience of HP Pavilion 15 damaged motherboard that sustained damage following the 1st year in a good state. I checked all the components like HDD, SSD, power cable battery, RAM, and HP advised me to replace the motherboard. The problem is similar – it creates noise when you connect your power cable.
Luckily, I was covered by an extended warranty and had my board repaired at no additional cost, The issue was solved. It is possible to bring your laptop to an approved service centre and request a status check on your motherboard. They will test your laptop against a different board (of the identical model) and summarize what you’ll do in advance.
If the product is under warranty, don’t be afraid to request a replacement.
The issue will be solved following replacing your motherboard, and typically it is. If the problem persists, your laptop could require an entire hardware inspection by professionals. If you have more reasons, go to this page, and I’ll update it regularly with the latest solutions and possibilities.
