Is it normal for a laptop to make a buzzing sound?
Yes, it is normal for a laptop to make a buzzing sound. The sound originates from the components of the processor. When the processor is in a clock-stop state of power, the laptop goes into power-saving mode.
This generates a voltage in the components of the power circuit of the processor. This leads to the components resonating and producing a buzzing sound, which is considered normal.
Why does my laptop make a buzzing noise?
Your laptop makes a buzzing sound due to changes in processor activities, cooling fans heating up or dust accumulating in the fans.

Laptop making buzzing noise when plugged in
Your laptop may be making a buzzing noise when plugged in because of a faulty hard drive, malfunctioning speakers, cooling fans running at full speed, laptop motherboard facing internal damage, or fans clogged with dust.
You will need to fix each of these reasons to prevent your laptop from making a buzzing sound when plugged in.
- Check the hard drive.
- Check the cooling fan speed when the laptop is plugged in.
- Check the speakers.
- Check the motherboard for internal damage.
- Replace the adapter if needed.
When the laptop has mechanical hard drives, then the hard drives are often a source of buzzing noise. They have fast-rotating components that can get damaged especially when you carry your turned ON laptop around. The surface of the hard drive can get damaged because of the scratching of the components on its surface.
The hard drive may also produce buzzing noise if the power cable is unable to supply enough power. To check if this is the issue, you will need to try and test a new hard drive with the same power cable. You will need to replace the power cable if it is causing the issue.
Check if the cooling fans of your laptop are running at full speeds for a long period when the charger is plugged in. This is not good for the health of your fans. To check this, you can try placing your ear near the exhaust of your laptop and check if you can hear the sound.
You can shine a flashlight on the fans to watch out for physical damage, or dust accumulation on the fans. If there is dust, clean it using appropriate cleaning materials. If the fans are damaged or broken, you will need to replace them.
You can also change the cooling profile of your laptop while charging to help the laptop cool more efficiently.
To do this, type “edit power plan” in the search bar and click the “Change Advanced Power Settings” link.
Click the “Processor Power Management” option to expand it. Expand the “System Cooling Policy” option and set the “Plugged in” field to “Active”.
- To eliminate the issues because of speakers, uninstall the speaker drivers and try using a headphone to check the sound. If the noise still comes from the laptop, then the speakers are good.
- To check the motherboard of your laptop, you will need to take it to a repair center and test the laptop using a new motherboard.
- To check if your laptop’s adapter is causing a buzzing sound when it is plugged in, you will need to remove the adapter from the computer and connect it only with the main power supply. If the LED on your adapter doesn’t turn ON and it creates a buzzing sound, then the adapter needs replacement.
