21 Nov Is coil whine bad?
The term "coil whine" refers to a type of sound that can be heard coming from a computer while it is running. It is very possible that the laptop is not the source of this noise, but rather a peripheral plugged into it. However, if the noise sounds like a high-pitched whine, and varies in volume depending on how much power the machine utilizes, then the culprit may be the laptop itself.
