Coil whine is a high-pitched noise that is caused by electrical current flowing through the coils of a laptop's power supply. It is usually caused by components vibrating due to the current and can be heard when the laptop is in use. It is often caused by poor manufacturing and design, as components can be poorly soldered or not properly secured. It can also be caused by components running at higher frequencies than they were designed for. To reduce coil whine, it is important to ensure that components are properly secured and that the laptop is running at the manufacturer's recommended frequencies. It is also important to ensure that the power supply is of good quality and that the laptop is running at the correct voltage.

As a regular laptop-enjoyer, how exactly am I supposed to check that the components are properly secured?

There's really nothing you can do about it. It's based on build quality and the components the manufacturer chose. Some people have had luck by putting silicone sealant into the coils, this obviously voids your warranty.

Thanks for your explanation.

So we can mitigate coil whine with coating the coils? Someone mentioned hot glue and you mention silicone…

I’m going to see if I can find more info on this.
