XPS 13 Kaby Lake: coil whine

Q: XPS 13 Kaby Lake: coil whine

Hi everybody,
Last week I had to return the brand new 9350 QHD+ because of the coil whine noise. It was a real pity because I was in love with the rest, but it was simply too loud.
Now I am thinking again what to buy.
Is the design of the new XPS 13 Kaby Lake (9360) solving the coil whine problem?
If yes, I would prefer to wait and buy the new version.
I hope that someone from Dell can give me an asnwer here. Thank you very much in advance!

Preferred Solution: XPS 13 Kaby Lake: coil whine

I recommend downloading and running Reimage. It's a computer repair tool that has been proven to identify and fix many Windows problems with a high level of success.

I've used it in the past to identify and fix everything from blue screens (BSOD's), ActiveX errors, corrupt files and processes, dll/exe/sys errors, recover lost memory, Windows update problems, defragging, malware removal etc.

You can download it direct from this link http://downloadreimage.com/download.php. (This link will automatically start a download of Reimage that you can save to your computer.)

This system is so new few if any users will have one in their hands.
Other thing to consider if it's an issue -- Kaby Lake will not run anything earlier than Windows 10, period - no work arounds, etc. It's Windows 10 or nothing (Windows-wise) -- if that's an issue.

I recently purchased the XPS 13 9360 (Kaby Lake) and have been using for a couple days.
I've noticed coil whine in the form of static sounds coming from the left side of the laptop, near the power connector.
There is very minimal noise when the laptop is on battery, where the noise is audible when your ear is next to the keyboard.
However, when connected to the power outlet the static becomes quite audible at a normal viewing distance. The static occurs frequently (especially when scrolling).
I tend to work in quite spaces with little ambient room noise, as I am easily distracted.
Is there a solution to resolving this coil whine issue? I feel like at this price point this should not be an issue (especially since is was well known in the earlier models).

Is there a way I could reduce coil whine on my HP Omen Laptop? What causes it?

Read other answers

Hey everyone,
recently there has been coming some strange noise from my computer. I haven't been able to pinpoint it exactly, but I think it might be coil whine from my PSU. I managed to take a recording of it uploaded it here:
(you will need to raise the volume quite a bit, the sound starts at about 10 seconds in) As you can hear, it's not constantly there. It lasts for 6-7 seconds and then its fine for about 25 seconds. Any help would be greatly appreciated.

A:Is this PSU coil whine or something else?

I don't think it is a PSU coil whine, otherwise it would be constant. I think I remember someone stating, coil whines are audible even after PC shut down. Audible after PC shut down because the coil still has power, which is what causes the whine.

Sounded more of a cooling fan squall, but with less volume. It could be a mechanical drive squalling. Drive casings will dampen a squall, so it's not as loud.

(I made http://en.community.dell.com/support-forums/laptop/f/3517/t/20022525 as well, but I tested it and the issue affects windows as well)
I purchased a Dell XPS 13 9360 (the new model). Overall, while clearly audible, I can live with the coil whine from the laptop. However, when I plug in my headphones, I can very clearly hear the coil whine over music while it is playing.
This issue affects both windows 10 and Linux, and so I think it might be a hardware issue. I really do love the laptop otherwise, so before I send the laptop back, I was wondering if there was any way I could get a USB headphone adapter (or a discount to purchase one).

I received my laptop yesterday and there is a buzzing sound coming from the laptop whenever I scroll or open a program.

I was hoping this wouldn't be an issue with the newer generation models, as it was my understanding this was fixed towards the end of the previous generation. Unfortunately, I have audible coil whine on my new XPS 15 9550 when plugged in to the power adapter. When disconnected from the adapter, the whine is much less noticeable. It is most noticeable for me when scrolling in Chrome, as an example. KB backlight makes no difference. It does get slightly better when the battery is fully charged, but is still quite audible to me.
Is anybody else experiencing this with the Skylake models? I am extremely disappointed at this point, I like everything else about this laptop other than the coil whine and the webcam being at the bottom of the display (which I can live with, unlike the coil whine).

Welcome to the windows 7 forums UdAkDev

Looking on google for coil whine shows a lot of hits and suggestions. One being that your PSU is not as powerful as it should be and another about some option in your graphics driver that you have to enable.

Hello, So my desktop computer is from 2009 its now 4 years old, lately i started investigating why this super high pitched noise keeps whining in my ear, so i opened my computer and started listening on some of the parts, i found out that it was the psu, The coil whine only comes up when the computer is in windows and while gaming, But when its starting up or shutting doen its quiet, I think this is becouse im almost overloading it or something but i really shouldnt, its using an 90W amd cpu and a engt 430 gpu, it draw's like 150-200 watts at its max and i bearly pushes it that much, even with gpu and cpu at max the computer is running fine,
the psu is 300W so im almost maxing it but still, it should not whine like this. Can i fix the whine in some way? i heard you could put nail polish on the capasitors to stop the vibrations and the whine came from vibrations or something...

I've received my new XPS 13 on 15h January, and there's a major Coil Whine problem with it, there's a high pitch noise coming out under the top left area of the keyboard, the sound is just like a dead HDD running.

Does anyone has encountered this issue? With their new XPS 13? Very annoying sound and now I need to wear a headphone to play music in order to filter out that sound.

TLDR * Has my new PSU caused coil whine in my GPU?

My 8 month old computer developed a strange clicking noise coming from the PSU, dell insured me that my PSU was faulty and so they replaced it with a new one.
With the replacement PSU, the initial noise disappeared. However, I am now getting a loud high pitched screech when playing games, it sounds to me like "coil whine".
I have been trying to determine whether the coil whine is coming from the PSU or GPU, as they are positioned very close together. I never had this coil whine BEFORE my PSU was replaced. Only afterwards.
Could it be that the new PSU is effecting and potentially damaging my GPU with this coil whine, or is the new PSU the culprit.
I specifically experience this noise only when playing overwatch, i have tested with BF1 and it runs silently, which to me seems more graphically demanding. I have not tested with other games.
I will post my spec below for further clarification. Thanks for reading, any help or response is greatly appreciated.

I recently had my motherboard switched by Dell on my new XPS 15 9560 due to a malfunctioning headphone jack. With the new motherboard with a working headphone jack I now suffer from coil whine. It is a low, buzzing irritating sound at all times. While gaming it sometimes becomes this high-pitched noise that is very irritating.
I had no coil whine issues on the old motherboard regardless of what I did. So this is not something I am imagining.
Is there anything I could try with drivers or the like to perhaps fix the problem? Or is a new motherboard the only option?

Replacement hardware is the only option -- while you can disable the low power states to lessen the problem, that will come at the cost of reduced battery runtime.

Hi Just received my new lenovo Thinkpad T550 with a Samsung 512 GB SSD and in a silent environment it makes a strange noise (fans are off - so this is not the problem): https://dl.dropboxusercontent.com/u/46679366/Lenovo%20sound.m4a This becomes quite annoying when you work e.g. at night. After doing some research in this forum I found that this is the "coil whine bug".  I just tried this registry change mentioned in a different post and it seems to work (however power consumption will go up) after rebooting the machine: reg add HKLM\System\CurrentControlSet\Control\Processor /v Capabilities /t REG_DWORD /d 0x0007e066 Undo:reg delete HKLM\System\CurrentControlSet\Control\Processor /v Capabilities /f However this cannot be the solution.

hello, in January this year I built a completely new pc to last me a few more years and I have been having some issues with sound. I think my problem is coil whine or related to coil whine. Whenever I have an excessive amount of fps like ~400 I get this medium-high pitch tone that sounds like coil whine only slightly lower pitch which varies with FPS. I can hear it through my speakers only. I can't see a way that high fps even soundless high fps can cause sound interference. Any ideas? Thank you

I've got an annoying high pitched sound that comes from my graphics card (I think) whenever I play a game with mid-high graphics requirements. Now, I've read a bit about the subject, and have come to understand that the noise is caused by vibrations. Also, based on what I've read, it is unfixable.

My question is this. If coil whine is NOT heat related, when why does opening the side of my pc up and putting a fan on it stop the noise? Understand, this is a powerful commercial grade fan, but if there is bad coil whine coming out and I put the fan on it, it takes about a minute to stop.

I'm really just trying to understand this issue properly, so I can begin to work out a solution.
Right now the best one is: keep a big *** fan blowing on it.

Any thoughts?

Greetings, I have recently brought an Acer Aspire E 15 E5-575G-53VG from Amazon. I have noticed a fairly high pitch coil whine from the upper part of the trackpad. The whine is especialy noticble when the charger is unpluged or when the trackpad is touched. The coil whine is loudest the laptop is unpluged AND touchpad is touched. I believe that I have the Synaptics touchpad but cannot comfirm, as device manager lists the touch pad as HID-compliant mouse. As for Windows, I have fresh install windows 10 and applied the anniversary update.

My Dell XPS 15 has an annoying "electrical buzzing" (coil whine).
The sound is only noticeable in a quiet environment but like most people that is the environment I do most my work in. Touching the touchpad (i.e. using the mouse) causes coil whine, holding down backspace causes coil whine, ANY user interaction with the notebook causes coil whine.
When left untouched I can hear subtle coil whine that peaks every second, but I consider that an acceptable level of sound as.
HERE -  This post suggests the cause is a faulty charger. I have had my XPS 9550 for near six months! Six months on a faulty power adapter due to the quality control on Dell's top of the line notebook.
What kind of damage could this have caused to the battery & other components?
Other Issues I've experienced with the DELL XPS 15 9550
- Speakers had terrible buzzing (software patch to fix this appears to be just lowering the maximum volume)
- Bluetooth Devices fail to connect but work fine with other PC's (Razer Orochi)
- Heavy Battery usage & overheat while it should be sleeping or off during transport (appears to be fixed)
- Display was replaced due to dead pixels in center of the screen. (CENTER - QC missed that on a 3K machine?)

I have a 3 month old XPS 13 9530 i7 512gb 16GB Windows 10 Model.
Over the last few weeks I have noticed a pretty loud (audible at over 10 feet away) electrical buzzing noise coming from the machine. The noise is worse if I scroll with the touchscreen or trackpad.
After speaking to Dell customer service, I have been informed by DELL that this is known issue (yep lots of issues documented on the web) but apparently this is completely software related (don't believe that either) and now they are refusing to help me unless I pay a fee for support technical support (I only have a standard warranty)
Firstly, I don't think this is just down to software. But am I the only person who thinks this is just unacceptable? I paid £1400 for this machine recently and now I have to use a pair of headphones to block out the loud noise.
I understand that software support is not included in the standard warranty but surely as this is a known problem I should not be subject to a further charge?
I'm starting to feel like I have been cheated...
Any help or advice would me much appreciated.

A couple of weeks ago I purchased a Latitude E5570(the best I could find from this series) and the very next day I found the following problems:- A coil whine noise was there almost all the time(very annoying, especially for a laptop produced in 2016);- I tired to downgrade from windows 10 to windows 7( I have a software from Siemens that requires Windows 7); even though Dell is saying that this computer should work also on windows 7 and they have drivers on DVD that came with the computer and also on their website I wasn't able to install all hardware components; I was not able to find drivers for everything inside the computer, and during the installation of certain drivers Windows crashed a few times; after a couple of days spent of trying to make windows 7 work I just gave up and installed windows 10 back;- Finally I realized the battery was damaged; Dell's battery test showed that everything is fine, but unfortunately I wasn't able to get more that 90 minutes of autonomy without having to recharge the battery;
So, I sent the laptop back and asked Dell for a replacement.

When the laptop is turned off and when the power adapter is plugged in, there is a significant noise (probabily the coil whine). You can hear it even in the recording that I took for the cracking sound! And I was just using my mobile phone without any other stuffs...

Skylake users given 18 months to upgrade to Windows 10 | Ars Technica

Help me understand how this works? I have a 6700k with w7 and w10. How does Microsoft know which CPU one uses with Windows?

Would, for example, a W7 computer with a 2600k get updates that mine would not?

If I were to get a Kaby Lake CPU and try to install w7 with it, what would happen?

Would only some useless power saving features not work? Would Windows 7 not install at all? What new features are coming in new processors other than power saving shenanigans? I have no idea what that author is talking about. I have installed multiple different Windows OSs via USB with NO "difficulty".

Furthermore, is this just fearmongering? It certainly seems like it may not affect consumers/enthusaists as much as the author implies.

Also, before anyone says "go to 7 forums", one will ALWAYS be comparing older OSs to the newest ones in regards to performance and compatibility thus I feel it's appropriate.

A:Windows 10 and Kaby Lake+

Newer processor may have some new instructions that older OSs don't know about. Similar things were happening in the past. Seems like MS is not going to bother with updates to older windows to be compatible with newer CPUs but Intel may come up with some patch.

I am an online chessplayer using a chessserver (playchess). Since switching to the XPS 13 I have lag times not experienced before. I have been online multiple times and the result is very much the same. Funny with my 'old ASUS UX31'  I have no such issues. At home I am connected to the same network, and my internet connection is via coax cable.
Since I thought this could not be true I did another test and set the Dell and the ASUS to do a ping test.
Firstly I pinged simultaneous (2 finger system) the chess server which is a long distance from my location (Australia to Germany) and then I pinged google. 
Out of 10 tries the ASUS got 8 times the better ping times then the DELL for both the chess server and google. The ping times for google were of course shorter then the chess server.
Beats me, any idea anyone.

HelloNow I know that Dell might not want to give any information about this topic, but I wanted to ask anyway. I will without any doubt buy a new laptop before the end of this year as my current laptop is so unstable that it is a complete no go at any exam.Kaby Lake quad core CPU's will not be hitting the market before 2017. However the nvidia 1050/1050ti will, to my knowledge, be released in October. Also there has just been a significant(around 100USD) discount on XPS 15(and the old 13) on the Dell website. At least on the danish site.This leads me to think that a XPS 15 refresh with a 1050/1050ti might come before the end of the year? Is this possible or are there no doubt that a XPS 15 refresh wont happen before Kaby Lake in 2017?Best RegardsEmil

E5-575G-728Q | Laptops - Tech Specs & Reviews - Acer

Reading on the internet, I cannot find a reliable source confirming if Windows 7 can be installed on Intel Kaby lake processors. Found sources telling me that you can and sources telling me you cannot.

I needed to try, so I booted an USB with a WIN7 iso using RUFUS and tried to install, however after starting the install I get this:

I tried to use both 3.0 and 2.0 USB ports, same error. I cannot load drivers from same usb or other USB as I cannot access them from there, so I am guessing that's not the issue. I also enabled legacy.
I don't even know what driver I would need.

Am I forced to install Win10? I would very much appreciate any kind of guidance as I do not like WIN10 interface.

Hello all,
Owner of a Dell XPS13 9350 which had coil whine audibly apparent from the top left corner of the keyboard/base and was at its worst when connected to AC.
After living with this issue for several months I finally decided to contact Dell Support.
To their credit, a week later a technician came to me to replace my motherboard.
This is unfortunately where my new problems started.
Immediately following the replacement, the keyboard was displaying an obvious pronounced lag between key strokes and anything registering on screen. The tech suggested it would improve with time, or that he could come out another appointment to reinstall windows.
Since this work, my laptop has been, for all intents and purposes, useless.
I have created a usb live boot of ubuntu which has displayed the same fault.
Windows 10 was also re-installed to rule out that possibility.
So, currently, I am left midway through study of the most difficult subject I will be studying, with a laptop that is completely useless for taking notes. As the laptop was purchased purely for studies, this i understandably frustrating.
Also, during this repair, the speakers on the laptop have stopped working!

Attempts have been made to contact Dell Support Australia, but they do not seem to appreciate the urgency of the situation.

Would any members here know of any further steps I could take to try and resolve this issue as quickly as possible?

(Don't know what happened to the first one I posted... Posting it again.) Hey group, While testing the performance of the SSD in my X1Y3 with CrystalDiskMark, I noticed a drastic performance drop in 4KiB Q(ueue)8T(hread)8 when connected to the Thunderbolt 3 Dock as compared to connected to AC power:  Dock: Random Read 4KiB (Q=  8,T= 8) :   318.764 MB/s [  77823.2 IOPS]Random Write 4KiB (Q=  8,T= 8) :   256.349 MB/s [  62585.2 IOPS] AC Power:Random Read 4KiB (Q= 8,T= 8) : 943.671 MB/s [ 230388.4 IOPS]Random Write 4KiB (Q= 8,T= 8) : 1024.264 MB/s [ 250064.5 IOPS] I noticed that with the Dock, the CPU usage during the test was only about 50%, whereas on AC power it was about 100%. (See the attached pictures). With the performance drop, I also heard very audible "coil whine". I can't quite tell if it was only coming from the dock or both the dock and the laptop. All connected devices were unplugged from the dock. The only two cables connected to the dock were the AC cord and the Thunderbolt 3 cable. The noise is NOT heard while using AC power. I thought the noise was just annoying before, but now with this performance drop, I'm a bit more concerned... Based on my experience with Lenovo Tech Support, I don't think I'd get any real advice from them. I was wondering if anyone else noticed the same issue and what do you think is causing it?  Thank so much for your help! ... Read more
