Re: Brand New T440S makes annoying buzzing noise (apparently when fan starts)

2014-02-05, 11:02 AM

Glad this is documented here and thank you Mark for acknowledging this is a real, persistent issue.

I have the same on my T440p, with 4700mq and Nvidia graphics. While I had the "whine" on my T400, what I experience on my T440p is more of a scream. This is at lower intensive CPU use states (not sure the steps involved)

 

If I have even the slightest activity, I don't believe it's there.. but it's at one of the idle(r) power states.

Is there a way to identify and possibly eliminate/skip a certain state, without disabling the entire CPU power management functionality?

 

I am afraid to turn my machine is as well, as I've heard many techs don't accept this as an issue, or claim not to hear it. But when you're sensitive and sit next to what should be a quiet machine, it's brutal...

My T440s (new model with i5 and Nvidia graphics) makes a similar high-pitched noise whenever the fan is running. It is not too loud, but definitely louder than the "normal" fan noise.

I just got an email from the distributer saying the humming noise is found in all the T440s w/ Nvidia they received from Lenovo last week. They suggested waiting for the next shipment to see if the issue is resolved by then. Needless to say, I'm really annoyed since the T440s has been out for quite a while and there still seem to be plenty of issues left.

at211,

 

Could you contact me by PM?  I would like to get some information on that email and distributor so that we can contact them for details.

 

Yingslaptop,

 

My point was that "CPU  whine" can occur and has for a number of product generations, and across multiple vendors. Searching other forums, and I think you will find examples.   Not all systems exhibit the symptom, and not all to the same degree - there seems to be some level of tolerances at play.

 

There was a specific service solution for T510, please see my PM.  However if you don't have one of those (and it is probably out of warranty by now), that isn't particularly relevant.

 

The focus on this discussion is to understand the sound being described on the T440s, whether it is tied to the fan itself or something else.  The statements in this thread seem to tie it to fan, which is different than the "CPU whine" issue discussed in some other threads you linked to, and related to my reference to the T510.

 

Mark

I also have a t440s with nvidia gpu and also this issue! I've got my t440s one week ago from lenovo germany, so it could be the same carriage as your t440s. This noice does not occure if "CPU Power Management" is disabled in the bios! Moreover i have a dualboot system installed and the noise also doens't occur in linux (ubuntu 14.04).

So in my case it seems to be some lower power cpu state, which is not (until now) supported by linux, causing this noise. The noise is located somewhere below the trackpoint and unfortunatly very annoying in quite surroundings, because its very irregular.

Thanks for your help!

unfortunately not, but i think if we could change the frequency in which windows sets the cpu in low power states the noise would be gone. Sadly i believe this can just be done within the intel driver... so nothing we can do :(

Do all, who notice the buzzing noise in the area of the trackpoint (not the fan noise!), have a dedicated nvidia gpu? Because in similar posts in the german section of this forum and in an additional german thinkpad forum it looks like that all people how have this issue possess a t440s with additional gpu!

Hi yinslaptop,

Can you tell us if you got this issue resolved?
If so how?

I bought T520 Thinkpad in 2012 and it had a high pitch noise, from the fan, which drove me crazy.

Since there was no solution even after many complaints from users, I ended up selling it, and lost money.


http://forums.lenovo.com/t5/T400-T500-and-newer-T-series/T520-fan-plusing-noise-every-5-seconds/m-p/924199#M70059

Wondering if the new Lenovos still got the same (or even new) issues.

Or are the new ones problem free? (although it looks like a wishful thinking)

I wouldn't mind giving Lenovo another try ONLY if they guaranteed that I can get a refund within 2 months, no questions asked, to peg my risk. 

If not, I'll have to buy a MAC.

Anyway, sorry I ended up talking about my issues,

would appreciate an update.

Thank you

Hi, the fan noise was easily resolved - I took the machine back to the retail shop and they agreed to an exchange (after all, it was only 1-2 days after I bought it from them). It seemed that the noise was a result of the unstable fan blades touching the computer. So the new machine was fine, without the fan noise.

 

However, what I subsequently complained about in this thread (and in another one I started) was a different type of noise in this new T440S machine - commonly known as the CPU whine - unrelated to the fan. It apparently had to do with the cpu coils resonating at inappropriate times/frequencies. It bothered me a great deal. After much back and forth, they then exchanged the motherboard. The noise did not really go away (although it did initially seem that it did). But after the frustrations, I just became resigned to it - and now the CPU whine does not bother me as much ...

 

But considering everything that happened, I really think I should have bought a Macbook Air instead. This T440S is quite expensive.

I see, thanks for the info.

The main reason I liked Lenovo was the feel of the keyboard but I guess it's not worth the trouble.
