CPU WHINE FIX

I'm wondering if anyone out there had their macbook sucessfully repaired for the CPU whine issue. I'm sending in my macbook tomorrow and I'm wondering if when it comes back - it will whine again (sooner or later).
If you got yours fixed - can you tell me please what components were replaced?
Thanks a lot - Trying to get this thing fixed once and for all - If it wasn't for this issue I'd be 100% satisfied as opposed to 50% NOW

no one? Not a single person got their MacBook fixed for the whine issue?

10.4.8 and cpu whine

Is there any difference with cpu whine after installing 10.4.8 patch?

I was not under the impression that the CPU Whine was software related. Most everyone who seems to have successfully combated the CPU whine has gotten their machine fixed (c.f. Daniel Jalkut @ www.red-sweater.com).
Apple's own tech article regarding CPU whine asks users to call Apple Care which seems to be code for: we need you to send it in.
I haven't had (or maybe just haven't 'heard') the whine, so I can't tell you what 10.4.8 does to it in this regard, but I'm guessing not much, one way or another.

Is this the infamous CPU whine?

I recently got a new logic board for my MBP, and since then, I've noticed that a quiet whine coming from it. The MBP is a mid-2006 model; the logic board was installed by AppleCare a week ago. The whine only happens when the computer is not plugged in to the MagSafe adapter, and it's fairly faint; it's just barely bearable. Is this the CPU whine that existed several years ago, or is this just normal behavior? I thought they would have fixed the CPU whine problem on new logic boards by now. I don't think I heard this whine before in the 3+ years that I've had this computer. If I do stuff like scroll a page or run CPU-intensive tasks, then the whine seems to go away momentarily, which seems to be what the old CPU whine used to do.

Download SystemLoad and run that. See if you can get the CPU to "sing."

MacBookPro 15" CPU whine: how to test, samples as .mp3

My W8614… MacBook Pro 15" still has the CPU whine, both with the power adapter plugged in (lower volume) and unplugged (higher volume). It emanates from both speakers even when the speakers are muted (volume zero).
My guess for the root cause is not separating analog and digital circuitry
properly.
I put up recordings of the CPU whine at
http://www.heusser.com/pub/macbookpronoise/noiseonbattery.mp3
The Utility SystemLoad (http://www.bresink.de/osx/SystemLoad.html) will
play the scale on the MacBook Pro by loading the processors

I haven't got used to mine since it came in February. I remember going to the Apple store to see about the whine and one of their staff told me to use photobooth to fix it!

CPU whine on macbook pro 13in

Hi, ive been experiencing the alleged CPU whine, and was wondering if apple will fix or replace my machine for a new one. Im under the 1 yr warranty.

fuad24,
Welcome to Apple Discussions.
They will fix it if they find there is a problem, take it into your closest Apple Store after making an appointment and they will look at it. Once they have then they will determine if there really reason to repair it.
Regards,
Roger

Still no whine fix?

I've had my MacBook for about 45 days now, and I'm not as happy as I'd like to be. The quality is worse than I have on my 4-year-old Dell: the mouse button is loose, the LCD bezel doesn't feel secured when the notebook is closed, the screen has uneven backlighting, and now the CPU whine. Even worse, I hear many of these problems are "normal."
I don't want to send in the unit for repair--I've heard stories of them coming back looking worse than they went in. I called AppleCare and all they wanted to do is send me through a maze of troubleshooting that didn't help whatsoever.
Is it too late to get the MacBook replaced? I mean, I know it's past the 14-day period, but do they make exceptions?
I'm very disappointed in Apple and expected more for my nearly $1700 investment.

You have up to 14 days to return your MacBook. As you've past that point by about a month, your only option is to have it repaired. If you're having problems, and you're within warranty... but you don't want to have it sent in for repairs, you don't have many options. There is certainly no harm in asking for a replacement... but as you haven't given Apple a chance to fix the problems you're encountering, the odds of them offering a replacement are slim.

X300 + CPU whine + Linux + how to disable C4 state

Hi,
I also have this annoying CPU whine occurance when my CPU changes to C4.
As I have Linux running on my x300 (Ubuntu 8.10) deactivating Power-Management in bios is not an option because then I cannot adjust the display-brightness with the function-buttons anymore.
Is it possible to deactivate C4 with a shell script?
EDIT/ I had to reinstall gnome-power-manager after deactivating power-mgmt in bios, adjusting brightness now works again.
Yet, my question still remains.
Thanks in advance

Advice: CPU whine

Hi all,
I've noticed over the last couple of months that my beloved MacBook Air (purchased June 2009) has developed an annoying CPU whine, more commonly associated with the early MacBooks and some MacBook Pros.
Just to clarify, the noise resembles a static crackle and originates from the left side of the keyboard, in the vicinity of the 'tab' key. It is easily differentiated from the gentle hum of the system fan, located in a more central location. Varying the fan speed using smcFanControl doesn't appear to affect the whine, which also persists regardless of power source - AC or battery. Just as a troubleshooting step, the noise disappears with QuietMBP set at 80 or 90. Tellingly, the frequency of the noise varies with the slider setting in QuietMBP as well. Unfortunately, this has the detrimental side-effect of increasing system idle temperature by 7-8C. :'(
I can't remember whether my beloved has always exhibited this noise, which then proceeded to get louder and discernable over time, or if it followed the application of an OS update. I first noticed it when running 10.6.1 though, and it is beginning to drive me nuts.
I will have some time soon to get it looked at by an AASP. What I'm wondering then is if anyone has had any experience with this problem, specifically with their MacBook Air, but also in general. Any advice or insight would be muchly appreciated by a poor graduate student being driven ever so slowly to the point of insanity. Oh, let the crackling stop...

My Macbook 13" does it and has since I purchased it in late November. I've brought it to the Mac store, spoken to "geniuses" and scoured the net looking for other people reporting the problem, and hopefully someone with a solution. I have found little of the former and none of the latter. The previous comment seems to make sense to me though. What I can contribute is that it seems to me be related to power consumption. The whine actually starts when my Mac is using little power, such during idle moments or low CPU usage. Crank the CPU up and the noise seems to go so that it is less noticeable or maybe even gone. My theory is that there is a power saving feature that when it gets engaged produces the noise.
I refuse to install the quiet program because I'd sooner return the machine. This is a defect and if it cannot be fixed then I will hold Apple accountable to their warranty. If you ask me, Apple is aware of the problem and is not making it known. Call me a conspiracy nut, but I found this thread through Google. When I went to click through to it, it mysteriously was not available as if it didn't exist. Other threads on the discussions board worked fine. So I loaded the Google cached version. Today the thread is loading. Go figure.
Additionally, I am contemplating trying a SMC and/or PRAM reset but I'm unsure of any possible side effects of trying those out.
Please anyone with additional info post. The whine is incredibly annoying and interrupts my actually being able to get work done, thanks.

CPU whine

Hello,
I bought a MacBook Core 2 Duo last week and I discovered it had a strange whine. It seems that this whine starts when the CPU is idle. I have found lots of information on the internet concerning this issue, but I haven't found any official sollution from Apple.
I would like to know what Apple is going to do about this issue. Should I ask for a replacement or should I wait for a software update?
Thanks for your answers.

What puzzles me is that Apple officially acknowledged the CPU whine problem on the Macbook Pro, and offered a fix for it. There is an article on their site somewhere, I've seen it listed in the forums here before. So why not do the same for the Macbook?
Anyone know if after sending the MBP in for this fix if it's completely eliminated? Or at least to the point you can't hear it in a silent room?
Also, I doubt very much you'll ever see a downloadable fix for this issue without taking a hit in battery performance. The only reason the whine goes in WinXP is because Windows does not throttle the CPU down as far as OSX does. As a result I can guarantee that you'll get less battery life in WinXP, and the same for all those other fixes. It's a capacitor, diode, or something else along those lines that vibrates when the CPU is throttled down. This is only speculation. In any case, if there was a way to fix it with software they would have done it with the MBP. But instead they asked for the units to be sent it, which is more incurred cost for them...so that would suggest it was the only way to correct it.

T510 on its way-- CPU whine question

The CPU whine ( likely inductor noise ) that I keep reading about makes me a bit concerned that I may have made an error in judgment .
Does anyone know what percentage of units have this problem ? Also what are most people doing to help reduce the noise level ?
Thanks, Bob

Yes, there are (my friend ordered a T510- the same one I have) and has no problems with whine.
I think it's a bit "luck of the draw", but if it whines, tell them to send you another one.
You do have a 14-day money-back guarantee on it (I believe this covers free replacement as well), so if you have the whine, tell Lenovo they can ship you another one- if they do it for hard drives (ship you a drive, you ship your old one back AFTER replacement) they should do it for full units too.
I would, however, call their sales desk and make sure of the time period to exchange a laptop (I believe it is 14 days but I could be wrong) and make sure you can keep your laptop while they ship one out to you. Continuously exchanging them should do the trick if they all whine/have any other problem- maybe it will spur them to actually fix the problem after they have to pay lots and lots of shipping charges.
I don't know when the T520/T420 (based on Intel Sandy Bridge processors) is coming out, but I certainly hope it doesn't have the same problems.

HP G62 B50SQ CPU Whine [HELP PLEASE]

Hello,
I have one HP G62 B50SQ laptop 2 months old now. Two weeks ago, it didn't powered on anymore so I sent it for warranty. They replaced the motherboard and the AC adapter. Ever since the laptop is emitting one very high pitch sound from the processor area which, as I identified on the Internet, I suppose it is CPU whine. The sound gets really annoying if I connect any USB device to the laptop (mice, or external hdd). Also the sound is present with the same intensity on AC or DC. I confess that it is very disturbing because I work most of the time in a quiet environment and I would like to know how it is possible to fix this. I've read on the Internet about disabling C4 state in BIOS, but the BIOS version that I currently have (F.47 , 2/15/2011) does not have this option. Also, If I send it back does the warranty apply or it is something that I should be supposed to live with? Thank you for your replies.

Hi,
My suggestion is to send it back, they must fix this for you
Regards,
BH

T420s - experiencing CPU whine that is getting worse

Hello there!
I have a Lenovn T420s with an i7-2640M CPU @ 2.80 Ghz, Optimus, and 8gb RAM. I got this laptop as a replacement from Lenovo since they severely damaged my other T420s while trying to repair the bezel.
This laptop is experiencing CPU whine that is getting worse and worse. There was no CPU whine at all whatsoever when I received this replacement in December, but now it shows up whenever I scroll up and down a browser window, click on a link, or do other normal tasks on the computer.
It happens regardless of if I am on battery or using the AC adapter. I've also read the other T410/510 page about the CPU whine and saw that the only fix was to get a new motherboard, CPU, and GPU. I also saw this post: T420s High pitch whine but it doesn't look like it has been updated for a while.
I have a 3 year warranty on this laptop, but I am hesitant to send it in without knowing if a good fix has been found. I already had a terrible experience with sending the laptop in for service, and had an even worse experience when the tech came on-site to work on it.
Anyone else with this problem? Has Lenovo come out with a solution?
Thanks!

Hi all,
I'm experiencing coil whine or "CPU whine" on my T420s. It's completely intolerable.
Rather than trying to describe this noise, I've put together the start of a sound album documenting it. Please listen: http://soundcloud.com/discostrings/sets/t420s-coil-whine
I suffered through 2.5 years with this problem on my T410. I sent it in once to resolve the problem, but it wasn't fixed. I figured the issue would be resolved in subsequents ThinkPad generations and I'd put up with it until it was time to upgrade.
But the whine on my T420s is much worse. It is impossible for me to use it in a quiet environment. But beyond that, some of the tones and clicking it makes are audible from feet away even in an environment with air conditioners running and people talking. I've tried (and recorded) every important combination of power settings. With all power management turned off in the BIOS and with the CPU limited to its lowest setting, it is ALMOST tolerable (but not quite).
I am willing to do whatever it takes to fix this problem--I do not mind parting with the laptop for a while. I would be happy to send it in for an engineer to look at and fix. I would be happy to take it somewhere. I would be happy to attempt to fix it to my own satisfaction if I am guaranteed it will not void my warranty. If none of those are options, I guess I'll send it in for motherboard replacements until I get a good one. But I'm going to have this fixed. Because this beautifully-engineered machine is impossible for me to use as it is.
As I understand it, coil whine results from faulty or low-quality coils or capacitors on the motherboard that resonate at different power levels. Unless this is from a rare bad batch (which I doubt because of my experience with my T410), this is a result of using bargain-basement coils and capacitors or not adequately testing the units from different suppliers. It's probably the matter of a few dollars or cents in manufacturing the computer. Beyond that, it can often be fixed with a drop of glue.
I put the recording album up to demonstrate that this is an actual problem, and to familiarize those who haven't heard it with the problem. I hope it helps other in diagnosing the coil whine.
Please let me know the best way to proceed to get this fixed. Thanks.

New Temp. Solution to CPU Whine

New temporary solution to CPU whine: MagicNoiseKiller.
This program was created by the same guy that created QuietMBP. This program is much better than QuietMBP. QuietMBP causes the computer to get hotter and forces the fans to go on and off (the mooing). MagicNoiseKiller does not use any processor power because it quits right after it loads. It does not get hot. It is the best solution so far to eliminate the CPU whine noise. Read more about it here: http://www.red-sweater.com/blog/108/macbook-pro-noise-i-believe-in-miracles
Download MagicNoiseKiller here: http://www.red-sweater.com/blog/downloads/MagicNoiseKiller.zip
With this program, I am extremely happy about my investment on this sweeeet laptop. It is silent as heaven.
Instructions to make it run at startup:
Go to System Preferences->Accounts->Login Items->Add MagicNoiseKiller

No way I'm gonna download the OS X update. I love MNK!!! I'm going to wait with the 10.4.6 download 'til MNK's updated. Besides, the new X update doesn't seem to fix the big problems. It's not worth it! I recommend MBP users (except for the ones who already did) to not install the new update until MNK supports 10.4.6.

I got my MBP back from AppleCare, LCD whine fixed!

Hello, I just got my computer back from AppleCare to get the screen whine repaired. It quiet as ever and I'm very happy. I've had no issues with CPU whine, ever.
-Jacob

Congrads! It's always nice to hear something positive from Apple. They don't have time to do it right the first time but they have plenty of time to it over again. Either way, its stories such as yours that keeps me from canceling my MBP order which scheduled for 30 March shipment. If it takes longer I will be happy to wait. Reason: I'm praying for a serial number: W8610xxx or grater, meaning manufacturing date of: "86" = 2006 / "10>" meaning week ten or greater in the production cycle. I would be even happier if shows week "11" or "12" in the suffix since Apple has identified units with serial numbers of: W869xx… or below that are more susceptible of having a defective “inverter” w/noise that emits from the upper right corner of the keyboard. This valuable information comes from another Discussion Member who got lucky with an honest and knowledgeable tech support dude at Apple.

Is CPU "whine" a sign of bad things to come, or just annoying?

I bought a MacBook Pro for my wife in April. It's been good -- especially after the firmware update cranked up the fans and knocked down the temps a bit -- but it has the CPU whine/buzz/high-pitched noise under the keyboard. Like the MBPs of other folks, it goes away completely if you open Photo Booth etc.
My question is, is this just an annoyance or should we worry about shortened lifespan of the MBP or other problems? My wife is loathe to give up the machine if it's not necessary, despite the aggravating sound.
I asked Apple Care this question and the rep said it shouldn't be a problem -- as far as she knows. I didn't find that as definitive as I'd like. What do you guys think?

There are different power saving modes, they are labeled C0 (full power) through C4 (deep sleep). By disabling C4 the CPU only can enter C3 (sleep) and therefore consumes a little bit more power. I don't know if this increased power consumption is significant, but I guess you will barely notice it.
