Terrifying sound on Samsung

by VistaVictim / February 13, 2013 11:22 AM PST

As I writing, I have a terrifying sound like a sharp pebble being scratched on a piece of slate, coming out of my beautiful brand new Samsung 900X notebook, running on Windows 7. The sound is coming out of the top-left area of the keyboard near the power socket, around the "2" and "W" keys, which I assume is the hard disk.

Is this some awful trojan attacking my PC, or has a piece of grit entered an air vent to interfere with the internal workings? Or something else?

Well inside warranty.

I'd either return it for another one without the issue or call Samsung to arrange for repair or explanation.

However I ran into a consumer that had their ear on the keyboard and were complaining about the noise. Since they could not hear it a few inches away there was not much else to do but tell them to return it for a more suitable model that passed their ear to keyboard sound test.

Ha. I could live with the noise if only I knew what it was - the sound doesn't bother me but am worried it indicates trouble.

My laptops still make some noise.

In reply to: maybe

But as the laptops got quieter I started hearing other noises in the laptops. As an electronics designer some made sense to me but let's say I get a new laptop with SSD. The noise we hear is dependent on the other ambient noises. So the unsettling noise could have been there all along.

Hope that helps, but do call them.

i like the SSD explanation. It's the first time I have one so maybe as you say without any whirring of disks and fans other noise is more audible.

And the SSD wiki says: "SSDs have no moving parts and therefore are basically silent, although electric noise from the circuits may occur."

So maybe it is electric noise, indeed it does sound vaguely reminiscent of the crackle of a copper wire with a loose connection, when the current jumps an air gap
