Dell XPS 13 making High-Pitched Noise (again)

Just letting you know that I sent you a message, Sujatha K.

Oh, I forgot to mention that I have the L322X version, and that link you gave me is for the L321X. So my issue is at the moment unresolved. Patiently waiting for another solution.

Status update: I have updated the BIOS to the very latest A08 revision. The noise is still there.

I am also experiencing this "high pitch noise"/electronic noise and think it may partially be related to the screen brightness.  Although this is not a "solution", I'm curious if it 'helps' others with this issue.  In order to test, I had to get "True" 100% brighness from the xps13.  In windows 8, I went to the Charms bar, hit settings, then "change pc settings".  Under "general", I disabled the "Adjust my Screen Brighness automatically".   With this option off, and with the computer under no load, and the fan not spinning, I would put my ear to the right-ish side of the XPS 13 so I could hear the high pitch noise, and played with the brightness (fn-f1 and fn-f2).  When the brightness was at 100%, the majority of the noise went away.   However, at any other brightness setting, the noise would be "loud" again.  Curious if others notice this as well.  

It is annoying though.  I am currently writing this using my macbook air, (because I wanted to see if my only other solid state laptop experiences this) and the Macbook Air is silent (at least from a normal distance.  I can hear a faint high pitch sound on it as well with my ear essentially next to the keyboard/screen, but nowhere near the loudness of the xps13, which I can hear from 1 meter away).

Hi GoonieG,

The screen brightness should not be causing any change in the fan functionality or there be any sound. Since you are experiencing this sound issue, I recommend you to flash BIOS from the link given in the previous post and also make sure the air vents are clean and the system is placed on a hard surface where there is good air circulation.  

If the issue persists send me a private message with the system service tag to check the system details. Click on my name and click Start Conversation to send me a private message.

Hi GoonieG,

You have mentioned the sound is audible only when the room is very silent. There may be some noise when the system is running. However I am not sure if it is the normal noise or something abnormal. I recommend run diagnostics to rule out any hard ware issues. Restart the system and at Dell logo tap F12 key every two seconds and choose diagnostics. Reply to this post if there is any error message.  Click on my name and click Start Conversation to send me a private message.

Also private message me the system service tag to check the system details and assist you further.

With that said, has only tried updating the firmware on their SAMSUNG SSD drives in these laptops? I have the option to return it for another 8 days so I am trying my best to resolve this issue and not have to do so.

I am in the same boat to. Got a new XPS13 and its has a very high pitched noise to it. So bad I can't stand using it because it gives me head aches. It came with the A08 bios on it already and Dell does not recommend flashing their bios with the same version. I see a lot of others complaining to, so I am probably going to try to stick it out for A09 and hopefully a fix to this issue. It's driving me insane.

@Askeptic...

you mentioned your SSD was a samsung?  Mine seems to indicate Lite-on.  Can you verify this?  I was hoping a different brand/model msata ssd would resolve this, but if your mSata SSD is a samsung, then perhaps not?

@GoonieG

Nice work to ensure it was the SSD. Yes, mine is listed as being a Samsung model PM830.

In my other computer I use a Crucial M4 and I do not have any of this noise issues, but the other computer isn't a Dell either.

Not sounding like an easy fix unfortunately. Was hoping something simple would fix it as it does get very annoying. I can return this laptop for a full refund if I do so in less than 8 days. I don't really want to do this as I do like the laptop a lot, but if its quiet in the room, this sounds drives me nuts.

This past weekend, I did some further investigation under the suspicion that it was the SSD (and not the LED screen like I originally thought...although sound is less when brightness is all the way up).  I created a bootable Linux Ubuntu USB drive to test out the theory that is could be the SSD making the noise.  There are several reports on ssd's with the symptons we have.  What i did to test this hypothesis:

1) Make sure noise is present when booting from Ubuntu Live USB.....it was...

2) remove xps bottom cover, and take out SSD (as described in the XPS 13 user guide downloaded from Dell's website)

3) Replace cover, and boot again from Ubuntu Live USB.  Sound was gone.

5) Install same SSD again.  Replace cover....sound is back.

So my theory is that it is either:

a) the SSD

b) current draw from the XPS causes some inductors, or capacitors or something else to generate noise (i.e. sound goes away with SSD out, because there is less current draw).

I'm leaning towards theory a), because I have seen reports of people experiencing these high pitch noises when they replace their regular hard drives (on their desktop, or laptop machines) with certain SSD's.

I would love to try a different brand, to validate this theory.  (My mSata is a liteon running a marvell controller.  My macbook air with no noise is running an SSD with a samsung controller.)

Oh, also if I try upgrade the SATA LITEON software, the installer tells me there is no LITEON product in my system, so I do believe the SAMSUNG PM830 is correct. (This is what the BIOS says it is at least)
