The notebook emits a short squeak at random times.

All sounds for devices muted, including speakers. Short squeaking sounds appear to come from within the laptop (under the keyboard) and not through the speakers.The sounds apppear to occur randomly. What could be the source of the squeaking sounds and how to stop them?

How long did it take from the first use of the laptop before the sound appeared. At my opinion the reason can be one of the following:

1. The laptop is new one and this is just the noise of the hard disk. Some hard disk make such kind of a sounds.

2. The laptop is old one and the hard disk is going to die and sounds are from the hard disk too.

3. What you hear is just the sound of the buil-in speakers on the motherboard and the sound appear when you press multiple keys or repeatedly press shift key.

I am not sure, so wait for another opinion.

My new laptop is doing this same random squeak/chirp thing, too.

The weird sound seems to be emitting from the left-rear area. 

It may be from a fan, as a vent is located in that vicinity, but I don't hear a fan running or powering down.

Strange...

Just found this possible fix, and have applied it to both the "Integrated Microphone Array" and the one labeled "External Mic."

I also right clicked on the speaker icon, and went to "Open Volume Mixer," and muted them both there.

I'll let y'all know if I hear (or don't hear) that sound again.

The checking of  "Listen to this Device" and muting the microphone fix (as seen in the above link) has worked!

The extra step of muting under "Open Volume Mixer" does nothing, as it gets un-muted after a restart.

Folks,

My Laptop is an HP Pavilion V2Z45AV with a 2TB harddisk from Seagate - Samsung, ST2000LM003 HN-M201RAD (Win10 Home 64bit).

I solved the problem of the HDD that was making such a clicking, creaking, squeak noise randomly every few minutes.
