Thinkpad T530 coil whine and fan noise

Q: Thinkpad T530 coil whine and fan noise

I am considering buying a used T530 with Intel CORE i7-3520M 2,9 GHz and intel HD 4000 graphics I own a T510 and the coil whine is bad. is this a problem on the T530 with i7?I understand that there's been problems wiith fan noise, but a bios update fix that. I am using Thinkpad fancontrol on my t510 and it works fine I understand Thinkpad fancontrol works on T530, but what is the lowest fan speed.? My T510 runs around 2400-2500 rpm at lowest speed and the noise profile is kind of annoying, should be a bigger fan really which runs at around 2000 rpm I am buying with the 1600 display which in reviews says is good. Anyone can confirm this?

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. I thought only older models are affected and now I am quite disappointed that even the latest model has these issues. BestKilian Posts worth to check out: https://forums.lenovo.com/t5/T400-T500-and-newer-T-series/Coil-whine-issue-on-t440p-and-Windows-8-1/...https://forums.lenovo.com/t5/T400-T500-and-newer-T-series/T450s-cpu-whine-or-fan-noise/td-p/2070850/...   

A:T550 coil whine noise

I have got a similar problem with the 90W AC adapter...it whines a lot.Now that I have installed two HDDs in my T520 I can't hear it that much but still at night it surely is annoying. It's moreso the frequency of the noise, rather than the volume.

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. Yesterday I received the new one.....and the show goes on:- The coil whine noise is still there, but even louder and almost permanent at this one;- I don't have the guts to make the downgrade from windows 10 to 7 any more; - I also order an E-Port replicator docking station and tried to connect an LG ultra-wide monitor(2560x1080).

If you have the X1 Extreme I'm just curious as to how often or how audible can you hear the coil whine in laptop? Mine varies for several seconds when I boot it up, when I listen to music sometimes, to long stretches upwards to a minute or two when on idle. The level of sound ranges from time to time but it's generally on the low side. Noticealbe in a slient room but not so much when there's other sources of noise around. I've look around to finding various post where it's pointing to the speaker settings, to undervolting, to just being a common issue in most laptops. Just curious as if do all Thinkpads X1E have this, does yours, and is there a way to reduce or remove it completely?

Hello everybody,

my new Portege Z30-b-138 produce an annoying level of electric noise (also known as "coil whine").

It is not a cooling fan or hard disk noise (the HD is SSD) but is coming from the motherboard and the pitch change as the workload increase or decrease.

Except for this problem, everything else is working fine.

Anybody know if this particular problem is covered by the warranty?
Can I RMA it asking to fix it for free?

Thank you

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

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.

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...

A:Psu coil whine is there a way to stop it?

If you desktop power supply is making noise and its not the fan Replace it. Do not try to fix it. A power supply can hold voltages for a long time that can kill you.
From you post #1.

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.

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).

My 20LD model of the X1 Yoga 3rd Gen (Intel Core i7-8650U) has a terrible coil whine. This noise comes from around the CPU in the upper right corner of the keyboard, around the F11 key. The noise is a high pitched scratchy noise that seems to occur when the CPU throttles up or down. The noise lessens when running on battery only. The coil whine seems to get louder and more frequent when the laptop is plugged into AC power. The only way I can completely eliminate the noise is by disabling Intel SpeedStep within the BIOS. However, this locks the CPU to the base speed. This leads me to believe that the coil whine within the X1 Yoga 3 is due to the fluctuations in CPU voltage as workload changes. I contacted Lenovo, and they immediately sent me a new X1 Yoga with the same specs. Unfortunately, the replacement unit exhibits the same behavior. Has anyone else found this to be a problem? Or did I get two bad units in a row? Anyone know of a fix besides disabling SpeedStep?

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).

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.

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?

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 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!

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.

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.

First of all, round of applause to marketing genius behind the new lenovo P1. He knows how to say all the right things to get customers to open their wallets and spend hard earned money, you had me at smaller charger, etc, etc, and the Aston Martin bit was classic.  However, I am no longer excited about using this machine after recieveing it because its so freaking loud. I work in an open environment and this machine gets so loud that it disctracts EVERYONE working around me. Just opening visual studio and loading a solution causes this machine to whine like blow dryer. What a joke. Lenovo, if you gonna have to throttle the cpu speed and spin up the fans like a generator why even bother putting these processors in here? I get it, it's thin, its fast and it needs to cool, but I don't recall my W520 disturbing the entire office. I've had to go back to my desktop while at work. When I am at home and I have no choice but to use this laptop,  even to me alone its disturbing. I bought a laptop cooler for the bottom that has no effect. I am not going to bother with a replacement because they all do this. I've tried disabling the integrated graphics, updating the bios to no avail. I've tried installing speedfan to control the fans, but lenovo's proprietory fans don't show up. I hope this is a software fix, lenovo please fix your **bleep**!

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?)

Hi, My x1 yoga was good except that the screen was flashing when dimming the screen. I sent to repair twice and the screen was finally fixed. They changed the motherboard and the screen. However now the laptop has two problems: 1. When I am closing the lid, there is a sound which sounds like mechanical cracking. 2. 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... But when I ship it to Lenovo's repairing depot and they just post "No fault found"... Is that what should I expect from such an expensive laptop? What's your suggestion?

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.

I bought a Lenovo V510 when it was on sale in Turkey about 4 months ago. Since I already had a laptop I did not setup that new laptop immediately till 1.5 months ago. When I started to use it especially at nights I noticed there is a very loud coil whine coming from the laptop when I leave it plugged in. I tried it with different outlet, bought a new adapter the coil whine did not go. Then I decided to send it to the Lenovo service. I was very disappointed with the quality of the Lenovo support. They are very unserious about the problem and very rude in the way they treat the customer. They are doing all kinds of tricks to prevent me from returning the laptop and ignoring the problem. In Turkey in the first 6 months if there is a factory problem I should be able to return the laptop and get a refund. My laptop is in the service for about 1 month. I have to travel for about 1.5 hours to go to the service (I did not want to use the shipping option since I did not want to deal with shipping problem like breaking the laptop). They are making me go there for the 3rd time in one month. Since coil whine is a factory problem I want to get a refund or get a new laptop. Can a Lenovo represantative help me with that?

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).

Recently I bought the Dell XPS 15 9560 and has given me a lot of issues with the wifi and coil whine. The issue with the wifi is that, when I connect with my network, all the machines on that network are disconnected, en the machine itself can not connect to internet. The coil whine, the sound is so loud that it is not possible to enjoy the machine, the machine starts making a lot of sound when I fire up a simple process. 
After encountering these issues I contacted Dell Service, and I could return the laptop and get a refund. Thanks for the great service Dell, seriously! But I really want this laptop, so when I get my refund I want to order the laptop again. But my question is, what are the chances that I get a laptop with the same issues again? 
Thanks in advance!

Hello, Just received a new X1 Yoga 3rd Gen with the i7-8650U. I received the machine with BIOS 1.21. With this BIOS, the fan was relatively aggressive when plugged into AC. This meant that I could easily start multi-core loads with ease. However, it seems that as of BIOS 1.24, the CPU fan isn't nearly as aggressive. Multi-core loads, when plugged into AC, enter very fast thermal throttling, and the fan waits a LONG time before kicking on. This causes heat to soak into the system chassis, worsening the issue. I also have a 1st-gen X1 Yoga, and while that was a dual-core setup (6600U), its fan is much more aggressive in cooling. The second problem that is caused by the fan not running as well is that SpeedStep has to constantly adjust clockspeed as it enters thermal management. The result? Guinea pigs. My computer sounds like it has guinea pigs in it, on some occasions. It's coil whine from varying loads and voltages applied to the CPU via onboard coils. In extreme load ramp-up cases, it sounds like guinea pigs. Otherwise, it's scritchy/scratchy/staticky noises. When the CPU fan comes in, and the frequency stabilizes, it goes away. Thankfully, the sounds are not constant, and like I said, when the fan kicks in, all is mostly okay. However, it's a bit surprising at first, to say the last. I've set BIOS fan policy to maximum performance, and disabled smart cooling; everything is set to performance. Still, the fan is highly reluctant to engage - I'd love if it did! ... Read more

Hi everybody,
Five days ago I got a Dell XPS 15 9560 (via Dell Netherlands) with the following configuration: i7-7700HQ, 256GB NVMe Toshiba, 8GB RAM, FHD.
In a few months I will be relocating to another country well Dell does not provide service support therefore, I am trying to make sure this device is suitable for the long run (i.e., 3-4 years, no gaming use).
I think I was unlucky and got a defective unit:

the left fan makes a scratchy noise that becomes more prominent whenever I change the angle of the laptop
coil whine
some back light bleeding

I contacted DellCares via Twitter and they are sending in an engineer to:

change the power supply
change the left fan
eventually change the mother board if the engineer deems fit

Here are two pictures and a recording of the sounds it makes: drive.google.com/open
I would like to get your opinion on three things:

Would you say the coil whine and back light bleeding on this unit are in normal limits?
Is it advisable to agree to a motherboard change on a brand new laptop?
The engineer is coming equipped with the following parts---do you how can I find what they all represent:

V363H - ADPT,AC,130W,CHNY,4.5,L6,V2,E5
VJ2HC - ASSY,FAN,LEFT,9560/5520
YH90J - ASSY,PWA,NBK,T,D,I7-7700,9560
0M5DH - SVC,ALSOSHIP,06335,N6370

I am really looking forward to hear your opinions on this and I highly appreciate any input!

A:Dell XPS 15 9560 coil whine - is a motherboard change worth the risk?

You may want to give serious consideration to returning the system for replacement -- tearing apart a brand-new system makes no sense.  it's as if you bought a brand new car and immediately needed the engine and transmission replaced.
Further, I'd think twice about keeping the system if you're taking it to a place where there is no warranty support -- either purchase a system that IS supported where you're going, or at minimum DO NOT have the parts replaced - have the system replaced with a new one that works to your satisfaction.
Notebooks are not designed for easy repairabilty and the potential for something going wrong with such major surgery on a brand new system isn't trivial.
