HP Pavilion laptop hiss/buzzing noise

I've got a HP Pavilion laptop that is about 3 months old. When I listen closely, I can hear from it what sounds like a low hiss/buzzing sound.

I don't think the sound is coming from the speakers because when I press the mute button to turn off the speakers, I can still hear the sound.

Is this sound normal or does it indicate there is an issue?

    Assuming it’s not the cooling fan, it’s probably some form of coil whine. Some people are sensitive to it. Others can’t hear it. It’s not really anything to worry about.

    Could be the WiFi module, try turning off WiFi and see if it disappears. Or, install "Soectroid" on Android and record near the laptop, if you get a constant noise at 50Hz it's probably something on the power supply side.
