    Problem with my T410s. Makes this high frequensy noise that drives me crazy

    It becomes mega massive when the turbo kickes in. This was supposed to be a super computer, but I am not happy. Am I the only one who has this problem?

    They took it (the sevice) once and said they replaced the Hard drive, the fan and the motherboard. Said if that didnt do it I will have to live with it.

    I didnt talk to lenovo, but to Nýherji which has the rights to Lenovo in Iceland and is like a dealer for the whole Iceland.

    What are my options here. Should I want a replacement?

    The computer is still under warranty untill september.

    Intel CPU whine.... Well documented throughout the net.
    No real solution, some workarounds (ThrottleStop, RMClock, Turn off C4).
    Either return it or live with it.

    Can I return it?
    How about replacing it?

    You could do either, but neither will help. If you're describing what I think you are, it's a property of the CPU, not the laptop.

    Yea, but wasn't that replaced on the motherboard swap?

    If you can return it, I would.

    This is so frustrating that I was even unpleasant to the people working there, but I know I should not.
    I would be happy with a same spec t420s with no noise. Thats what I want.
    I bought the computer and am mailny in the livrary reading. This sounds isnt helping. The answer I got from Nyherja that is the dealer of lenovo in Iceland that I should just have headphones!!!
    **bleep**??

    Oh yes the T420s can have the same whining noise.
    Even more worse is the fan noise issue, which I heard that when throttled up to high rpm's, won't return back down to idle.

    To quote some other people:

    The whine is caused by capacitors oscillating during CPU sleep states.
    It's due to electrical charge being not used by your PC (less than the maximum output) so the capacitors will literally vibrate at such a high frequency you can hear it.

    By the way, the T4_0s series CPU's are BGA soldered, there is no upgrading besides swapping out the motherboard.

    I will go with my laptop "AGAIN" tomorrow and leave it at the service. This will be the third time I leave it there. If the noise will be still there I will be wanting a new computer.


    I bought this laptop and it was the most expensive one in the shop just to be problemfree. It went the other way around.

    Here are some troubleshooting steps that may or may not help. Turning off CPU PowerSaving helped, but it's unrealistic to use it daily.

    I wouldn't bother returning it. It's a property of pretty much all Intel CPUs for many, many years now. Ever single x86 notebook for many, many years has exhibited this in varying amounts.

    Unless you're describing something different than the well-known CPU whine, I hate to say it, but it's not a flaw. It's just a property of the CPU.

    So far I have not heard it. Maybe all the rock concerts were a good thing after all.

    Well, thats not my problem that the CPU is faulty. I wont let them tell me to live with the thought I bought a faulty product not knowing of the problem and just going to live with it

    Don't give up. Harass them until they exchange it, swap it for another model, or take the laptop back and reimburse you.

    It's not faulty. It performs as specified; as far as I know, none of the spec sheets specify which sound frequencies it can and cannot produce during normal operation.

    Badgering them for a replacement won't get you anywhere, and personally I wouldn't bother. To each their own, I guess...

    It's varied from machine to machine for me. My first-gen MacBook produced a very audible whine when it was clocked down, but my T60 from the same era produced a far-less-audible sound. The T61 that I'm using now whines very slightly, but my T420 is definitely audible at close range in a quite room. The audibility of the whine probably also depends on case design, manufacturing variances, and a whole slew of other things that I'd never guess since I'm not an EE/ME.

    This also seems common with the T420s. At least I'm affected by it. Here are my recordings: T420s Coil Whine by discostrings on SoundCloud - Create, record and share your sounds for free

    I think this is incorrect. It's not Intel's problem; it's that some manufacturers use cheap coils and capacitors. Manufacturers who pair Intel CPUs with cheap coils and capacitors end up with audible whine, while those who buy good components do not.

    It's pretty clear how this played out. Intel introduced the Core Duo, which used power in a more dynamic way than previous processors, and suddenly it was clear that many manufacturers were using coils and capacitors that weren't appropriate for those power states. In the subsequent 6 years, some have chosen to use better quality components, and others have chosen to build machines that kill your ears when you use them. But for some reason the perception that Intel CPUs are directly responsible for this noise persists. Instead, we need to hold manufacturers to account for using bargain-basement components.

    It's a variable problem in any particular model because they don't all end up with coils and capacitors from the same manufacturers. I say: absolutely return it until you get an acceptable model. At some point the manufacturers will realize it's not worth the few dollars or cents the cheap components save in comparison to the returns and replacements.

    typing "cpu whine" in the google then I found that all the major brands are mentioned ... mac pro book, hp envy, thinkpads, dell, but I have not noticed it on my three thinkpads, my two Dell do have them though.

    It is described to some extent in this Dell Tech Support article. Journal ID: 10019BMDJ8, Article ID: 295216

    "In certain situations, an intermittent, high-frequency buzzing noise may be heard from the system. It appears to change with processor activity and can increase in frequency if USB devices are attached.

    This buzzing noise is apparent to some degree on all laptops but is perceived as abnormal because it is different from the other more familiar noises the computer makes.

    The noise has been isolated to the processor’s power circuit and is only audible when the processor is in C3 (clock-stopped) power state. In this state, the computer is in a low-power mode designed to reduce chassis heat and extend the battery life. The changes to the components in the processor's power circuit are caused by a phenomenon referred to as the Piezoelectric Effect. When a specific voltage is applied to these components, they begin to resonate producing sounds that fall within the range of human hearing (15 – 20 KHz).

    The noise is normal and within the acoustic specifications of the computer"

    This would imply that Dell, HP, Apple, Lenovo, IBM, and Sony have all used "cheap coils and capacitors" in all of the machines that I've observed this with. Amazing that they've all gotten away with it for nearly a decade across dozens of machines.



    ... or maybe there's another explanation.
