Thinkpad Yoga 12 20CD extreme fan noise

Hi,
Last week, I had my Thinkpad Yoga 12 serviced, as it didn't boot anymore. The whole interior got replaced. Since then, the fan noise is really unbearable. It was the same when I initially bought the machine, but then, a BIOS update (don't know which anymore) fixed it. It's a loud high-pitch noise, like a whissle.
I need urgent help, my collegues are complaining of the noise.
Best regards,
Jeroen

Well here I am on the new thread as well - and like heck the issue was resolved on the old thread. As mentioned before by myself and others on the other thread, I would update the BIOS, the fan would work for a while, then it would stop again until I updated the BIOS yet again.HOWEVER, thinking on this, and a variety of other problems I've been having with the TP Yoga (a whole lot - such buggy software), I remembered from my T61 days that the Lenovo System Update software is pretty hit and miss with finding updates. So I went to the Lenovo downloads page for the TP Yoga and indeed found a lot of software not passed onto me by the System Update.Amongst these was (TA-DA !) a utility "Lenovo Fan Test for Windows". I thought it would be useful to install in any case to test if the fan was operating properly (it was not part of the standard suite of diagnostic tools provided on my computer).Anyway since I installed it my fan has worked !!! - but only when my computer is plugged in, though this I believe is because I am using Lenovo Power Optimized (Lenovo Power Manager was another software on the site not provided to me via System Update) which I believe relies on passive cooling (throttling back processor) when only battery power is available. But now TpFan works all the time, though only in smart mode, and when I plug in the power to stream a video the computer doesn't reach boiling point and then shut down.Interesting. My fan diagnostic comes up as unavailable...

Yoga Pro 2 Fan noise tweak fix?

The MBA (at least my old 2010 model (which was a total lemon)) definitely has a substantial fan which kicks in under load (gaming etc.). You don't see vents because they just use the crack along the hinge line to get the air in and out. Yes, this means there's less exposed vent area but you still have to worry about blocking it say you were using it on top of a blanket or something.
Also if your MBA ingests, say, enough cat hair to block the fan intake, then good luck getting at it to clean it out. I had an old Dell gaming laptop that became unusable until I opened it up and pulled the 1/8" mat of cat fur off the face of the heat sinks.
Over time the inside of your laptop can start to look like that furnace filter you haven't goten around to changing in a year or two, depending on how the airflow goes. Usually the air gets pulled through a heat sink and the outer face of the fins can collect stuff.
Someday the power dissipation may be such that we can have completely sealed dust-proof machines, but until then environmental concerns over time are still a big pain.

Extreme fan noise on Retina Macbook Pro "15 2012

My Macbook runs very loud without intensive apps open when I connect it to a Thunderbolt Display for over an hour. I have tested this to great length, it doesn't matter whether it's photoshop, microsoft word or google chrome that's running, it's the fact that it has to power an external display.
I have taken it to Apple Support, however they perform their cooling system tests in 18 degree airconditioning so it's impossible to demonstrate how loud it gets at normal room temperature.
I presented this problem twice within my warranty period, but Apple will simply do their test and deny any problem as the fans barely start up in the cold test environment. They did say that if my laptop overheats and becomes damaged, they will cover the damages because I made the complaint within the warranty period. Now my warranty has expried (I simply didn't have time to waste taking the computer to Apple again within the last two months).
Is there anything I can do to get my laptop fixed? I'm pretty sure the graphics card was faulty to begin with as it cannot take the load of a Thunderbolt Display over an extended period. There are so many documented cases of issues concerning fan noise and overheating with the 2012 rMBP, is Apple not going to do anything about it?!

High CPU usage will make the fans run faster (luder) you can try a SMC reset:

Follow directions for a battery that should not remove yourself. Also have the Apple tech make sure you do not have a bad temp sensor.

Thinkpad Yoga (TPY) Cooling Fan Failing Already

The cooling fan in my TPY (20CD0033US) has already nearly failed. The fan makes loud grinding noises at all times while spinning, and starts making a much louder noise (which won't cease until the fan is stopped and restarted) if the TPY is tilted past a certain point during operation.
I bought my TPY for doing work, but I've also been using it for some gaming while in bed, due to my bad back. My guess is that due to the fan working hard on a regular basis, its bearings are prematurely failing. So now I keep the power profile set to limit my clock speed to 800mhz to prevent the fan from spinning most of the time. Naturally, 3-D gaming is out of the question at this point.
Even with my usage pattern, I'm very surprised that the cooling fan is already failing. I want to believe that my cooling fan came with defective bearings. Is anyone else's cooling fan grinding to a halt already?
I probably should have gotten the T440s, it appears to have a superior cooling system afforded by its thicker chassis.

During the second repair session they were able to fix the problem. But I am really unsatisfied with the repair service. I opened my Lenovo to switch hard drives, they "forgot" 3 screws, one was lost unscrewed somewhere inside the laptop and none of the two harddrive screws remained.
In essence, I would suggest to send in the TPY and stress the problem, telling them that the fans start to physically scratch against the laptap case when the CPU has an elevated work load. I think they have replaced the fans in my case, but you can never be sure and have to test your hardware again.

Thinkpad YOGA touchpad loud clicking noise.

I am quite happy with my Yoga and sensitivity of my touchpad, however the clicking sound is ridiculous, it is very loud and can be heard in the next room Someone already uploded a video showing it: http://youtu.be/XPJ7D96EAY8
I have tried new T440p, it has the same type of touchpad, but it is much much smoother and quiter.

Yep, just want to throw in my agreement that the touchpad physical clicks are unusably loud. Both the upper buttons for the trackpoint and the lower buttons for the trackpad itself. Lenovo, PLEASE fix this in future versions. Or in this version.

Macbook Pro 15 Late 11 extreme fans noise when using external monitor

Dear Apple, recently I bought Macbook Pro 15 Late 11. I really love it's speed and new OS X Lion, BUT this Macbook really noisy when I use external monitor and keyboard. I work on external monitor all the time. I don't care about how hot my Macbook is when I'm on external monitor. Let it just be hot and quiet.
P.S. Example. I run Ableton Live and have 6200 RPM working on external monitor (awfully loud!). CPU 90% idle. When I switch off external monitor and use internal one, RPM drops down to 4500 with the same Ableton work session. By the way, I don't need cool graphic card. Apple, let our work days be quiet.

I did that and it didn't help. It's common problem with an external monitor. Here are some links:

Thinkpad Yoga, not waking up after sleep

I have an issue with my Thinkpad Yoga (20CD).
Sometimes after I have left my Yoga unattended. I come back and find that it's on (red light on) but screen is black, but nothing happends when moving mouse or pressing keys.
I believe this is happens with regards to sleep mode.
I still have some analysis to do wether it happens when power is connected or not, external monitor is connected or not.
I have installed all the latest drivers from lenovos website.

Hi Henrikh,
Welcome to Lenovo Community Forums!
I’m sorry to hear that your ThinkPad Yoga goes to sleep and doesn’t resume normally.
To disable the system from going automatically to sleep mode, go to control panel -> Power options -> on the left hand side, Change when the computer sleeps -> Change “Put the computer to sleep” to never.
To enable a device to wake up the system from sleep, Go to control panel -> Device manager -> Go to "Mice and other pointing devices" and double click on the mouse which you are using and check "Allow this device to wake the computer". Press OK.
Do the same for keyboard as well.
Do let me know if it helped!
Best regards,
Mithun.

Yoga Fan Noise

I have a new Thinkpad Yoga model 20CD-0038UK
Anytime I use any software/app which has sound capability the fan then goes to full blast and is very noisy.
for windows 8 apps the only way to stop the fan is to kill the app in task manager.
Playing an mp3 file the cpu is at less than 5% and the fan still goes flat out.
Stopping "windows audio device graph isolation" audiodg.exe also stops the fan noise (but then no sound from the laptop.
I have now tried a factory restore on the device but this has made no difference.
I understand this is not normal for the TPY which should manage to play music/video without fan cutting in.
Any advice?

That isn't my experience at all. I have the i7-4600U processsor and my fan rarely turns on. Those instances are usually processor intensive like Miracast (projecting to a HDTV) or hardware scans. Can you hit the CTRL-ALT-DEL to open task manager and find what application is using resources (e.g. memory and processor) to require the fan? Usually, that will help guide you down the right path to getting a solution.

Thinkpad T60 fan noise

Hello
I own a Lenovo Thinkpad T60 laptop. Lately fan of my laptop started making a whirling sound. Its been only 2 years since i have purchased the laptop and now i am running with this horrible fan noise.
I want to replace the fan with a new one. So i have checked the hardware manual of Lenovo and found out that at some point i have to apply thermal great at a location of fan assembly at the time of installation.
What thermal grease i have to use for this. If i buy the fan assembly at Lenovo, will they send me the thermal grease also.
Also do i need to buy the same fan model as the existing one... If it so, where can i find the fan model in my system..
Your responses are greatly appreciated.....

Hello,
the simpliest method is to use your 3years warranty and send it to depot.
The other way is to do a parts look-up on Lenovo support page, see link on top of this page.
Then your get the FRU number, search for it at Google, also for thermal grease like Arctic Silver.
The fan isn´t very expensive may be 30$ and it´s not difficult to deploy it. But you will loose warranty!!
Regards
Andreas

Thinkpad Yoga - fan sounds like a plane

In tablet mode (and mostly when the tablet is horizontal) then the fan (I suppose it is the fan) makes some horrible noise. I can't work with it at work in this mode as my colleagues look at me weirdly. When I lift up the screen a bit, then the fan stops in a struggling sound.
I did a video of the issue:
https://www.youtube.com/watch?v=e0Y0hEr3qKc
It's a shame because in latpop mode it doesn't make any sound, even thought the work I do in laptop mode is much more intensive. Would not be for the sound, this is the best laptop I ever had. The keyboard is great, the edges are not sharp, the screen is beautiful, the wacom pen works perfectly. An awesome computer.
Anyone one had this fan noise issue?

Hi,
Welcome to Lenovo Community Forums!
I’m sorry to hear that fan in your Lenovo ThinkPad Yoga is making noise.
If your laptop feels hot and shows any of the problems below, chances are its overheating or getting there:
Fan constantly running and making loud whirring noises
Computer struggling to perform basic tasks like opening a new browser window
Mysterious error messages popping up in random programs
Lines on your laptop screen (a sign your video card is overheating)
System freezing or the dreaded BSOD (blue screen of death)
The laptop abruptly shuts down on its own
First of all, update BIOS to the latest version.
Use dust remover spray to clean out of the laptop's vents. Dust can accumulate in and block the laptop's fan vents. Start using compatible cooling pads which will help in the flow of cool air into the underside vents of the laptop. Keep your working environment or computer room as comfortably cool as possible. Check if the fan is touching some wires during spinning to cause the noise.
Best Regards,
Mithun.

Problems with new Yoga 2 Pro (battery, fan noise, yellow, screen orientation, on-screen keyboard)

I purchased the Yoga Pro 2 on Thursday October 17. I love the computer for so many reasons, (especially since it replaces my 4 year old Compaq that was 6.5lbs!) however, I am also having a few issues with it.
It is the i7/8GB/256GB model from BestBuy. I am experiencing the same yellow issue as is mentioned by many on here. I didn't realize it, though, until reading these forums and then comparing to my old computer and my ipad and iPhone. A little disappointed, though it looks like Lenovo may be working on a solution.
But the real reason I originally came to look at this forum is because of 2 things: my fan and battery.
The fan (on the right side of the keyboard) is always on! I didn't expect this, and am wondering if mine is a lemon or if others are noticing the same thing. It's pretty noticeable, especially in a quiet room. I was showing off my new computer to a friend and the very first thing she said was that it was loud! She was using a MacBook pro, which wasn't making any noise at all.
The second thing is the battery... I am attaching 4 photos all taken within a few minutes of each other. If you cant see them, they are all of the battery meter on my screen. I am listing the time of day (to show how much time passed), percent remaining, and time remaining:
10:04 (88%) 306 hr 15 min
10:05 (88%) 8 hr 48 min
10:09 (86%) 4 hr 54 min
10:29 (81%) 5 hr 12 min
I feel like my computer just cant make up its mind!!
Another issue I had... I turned on my computer to show it to a friend (same friend who said it was noisy) and the screen image wouldn't flip when in any of the modes. This means I showed her the stand mode with an upside down image. Even in tablet mode I couldn't get it to flip. I turned the computer off and then on again, and luckily it decided to work, but it was frustrating, and I hope it's not something that becomes an issue.
Also, when I have the computer in tablet mode, the keyboard automatically pops up when I click somewhere to type... but this doesn't happen in stand mode or tent mode. Is this normal? I would have thought that the keyboard would appear in any of those modes, since the real keyboard is not accessible in any of them. And of course now that I am testing it out while writing this, none of the modes (including tablet) is having the keyboard come on screen. Of course, I know I can always choose the icon on the task bar to bring up the keyboard, but it would be nice if the computer did it automatically since it knows there is no other keyboard accessible in those modes. Is this an issue anybody else has had?
I really do enjoy using this computer, but some of these issues really need to get worked out if I am going to keep it. I'd love to hear if anyone is experiencing anything similar, and if there are any good fixes!

I just got a Lemontine Yoga 2 Pro i5/8GB/256GB from lenovo.com and the silver one from BestBuy in the same configuraiton. The silver one has no issues except for the crazy number of hours remaining on the battery which is fine, doesn't bother me. The fan noise is very quiet, and you can only hear it if you put your ear up to the vents in a quiet room.
Now the Clementine one...It was heating up pretty good. I put my ear to it on many occasions and can hear nothing at all, the fan is either missing LOL or doesn't work. I had an issue where I left the thing on for 4 hours, but sleep is configured after 5 hours. When I tried to use it, it showed me the screen brielfy, then blank. Tried hard reset, called Support, nothing. Support says its dead. Ok, an hour later, it turned on. I'm guessing it was too hot and was in some mode to protect itself, like a smartphone that is left out in the sun for some time, it won't power on till its cooled down.
I'm still in process of trying to get a hold of Lenovo to swap it, but since they no longer sell this configuration, I doubt they'll be able to get me a new one.
The silver one from BestBuy us solid though, love it, best in class in my opinion...actually got it from Future Shop sorry...from Canada, but they're essentially the same store.

Fan racing intermittently, no CPU load, Thinkpad Yoga 15

I just purchased a Thinkpad Yoga 15. I was trying to fix its disabled discrete graphics card. One thing i did was update the BIOS. I think it's after this that the fan started to intermittently race. It's silence, then runs loudly and annoyingly for a second or two, slilent again, then randomly continues. Before the upgrade it was silent all the time.
This is terrible. Anyone has any ideas?

Fan Noise Thinkpad 420 418062G

Dear all,
I bought Thinkpad 420 418062G notebook 3 weeks ago. The notebook is good one. However, I have a feeling that the fan noise is lauder than usual. When I run Thinkadvantage tool box, it says my system is running healthy.I google for possible solution, and tried to update bios from support page(it shows I have 1.37 version Bios). Still, the problem persists. other than that, the notebook is running fine , there is no overheating issue. Do I have to worry about fan?
Please suggest me.
Thanking you in advance,
Vidur

vidur123,
Try going to Power Manager check if Intel Turbo Boost+ is enabled. If it is then its normal that the fan is running at high speed.
Also in Power Manager, switch the view to Advance then change the fan to balance all parameters.
See if it helps.
*Non Lenovo employee*
I have a Y2P (i5) ... Feel free to ping me if you want me to test some applications with your Y2P if you have the same model. I don't mind keep doing recovery on it if needed .... =)

Thinkpad Yoga: Strange honking sounds and audio/video glitches

WARNING: LOUD VIDEO EXAMPLES
I have a Thinkpad Yoga, type 20CD with Windows 8.1, and when I'm running some white noise to help me concentrate, I get these strange honking noises that are quite disruptive. Even worse is that when I'm trying to watch a video on youtube, the honking noise occurs and this seems to lead to quick stalls in the video as well (note: the major stall in the middle of this video may just have been a bit of lag, I meant to highlight the minor stalls like the one that occurs at around 2 seconds). Actually, it seems that the honking causes the entire system's video to stall (e.g. cursor stalls, clock stalls, etc)
I've found only one other thread dealing with this issue and it wasn't resolved.
Addressing the suggestions brought up in the linked thread:
1) The problem occurs regardless of if I'm using the laptop's built-in speakers or my headphones. I don't see any reason to hook it up to my TV and check HDMI out.
2) Yes, problem persists with headphones.
3) The problem occurs whether I'm using the lowest quality or the highest quality audio.
4) It's the whole system, not just one application.
5) The microphone has nothing to do with it. Enabled or disabled, the problem still persists.
I've updated my audio drivers but this hasn't done anything to mitigate the problem.
Strangely enough, what does help is turning off my WiFi (i.e. Fn + F8). When the honking is occuring, I can switch the wireless card to airplane mode and the problem immediately goes away. I've read somewhere that this may be because of poor grounding on the audio card, meaning that the antenna is possibly picking up radio signals.
Are there any possible solutions to this problem?

Audigy shares IRQ with IDE controller and firewire controller. This is not good.
NOTE: I suppose you're running your PC on "Standard PC" -mode (since IRQ's >5 not showing). If so, you can try to assign IRQ for the PCI slot, Audigy is installed, manually from BIOS. See your motherboard manual page 4-26.
Can you check if your PC is running as "Standard PC" and not as "ACPI Uniprocessor PC" (Device Manager --> Computer). Make it "ACPI Uniprocessor PC" --> you get more IRQs (virtual) in use.
NOTE: You may need to reinstall OS to get this done.
Also you may need to enable APIC mode on BIOS.
How To:
A) Go to 'Device Manager' a short cut to get there is "Right Click" on the My computer Icon on your desktop (Control Panel --> System --> Hardware),
B) Next click on 'Computer', then double click on 'Standard PC'. Then select 'Driver' and then 'Update Driver'.
C) At this point you will see a screen pop up asking you to do this "Automatically" or Select 'Display a list of the known drivers for this device', - Choose this option.
D) Next you will see - 'Show all hardware of this device class'. Now you can select "ACPI Uniprocessor PC" in the list shown in the window to the right.
E) Now Windows needs/will re-start and re-install all hardware/ settings needed to run in this configuration.

G580 loud fan noise

Well a lenovo, used for a year and a buzzing loud crackling fan noise problem... Aren't we surprised!!!
Useless to ask for a BIOS update for a essential product, they didn't care to give one for a thinkpad.
Here's the problem though...
The laptop makes a buzzing fan noise. That is not a fan running at full speed. This noise is more like a buzz of a large fluoroscent tube. And will stop, well, if you tap it, knock it, or use your acquired accupressure massage tricks for the revered Lenovo products. Problem is it will reappear after a few minutes or seconds depending on your luck.
Lenovo don't seem to provide any off shelf fans at least in India for the product. Even the cpu temp seem to be rising. It has touched 70C for i53210m.(room temp at 26C, load 100% for arnd 30 sec, avg load 6%)
My question is with the temperature on the higher side, and the fact that I cannot feel much air from the fan, how do I know the gurgarating buzzing loud fan is actually working or needs to be changed?

Hi pkj5ue,
You can get access to the fan by removing the bottom cover and taking the 3 screws out and removing the keyboard. The fan will be visible at the top left. Blowing come compressed air in through the vent and vacuuming out through the fan should suffice for a simple cleaning.
Here's videos showing disassembly of the various components.
If you need to replace the fan or reapply the thermal paste, yes, you will have to disassemble the laptop.
Regards,
Dave
