C2D MacBook -- the CPU whine is GONE!

So, my black C2D MacBook has been up and running for the past three hours, and there is absolutely no hint of CPU whine!
That's my happy ending to a very sad tale of one bad rev. A MacBook after another...
This is the FOURTH MacBook I've had in the past six months. The first one was damaged right out of the box (misaligned case, and screwdriver scratches all over the bottom), so Apple replaced it. The replacement machine developed a really loud, grindy noise coming from the fan, and after two trips to the Apple repair center with no improvement, Apple finally agreed to replace that machine last week. The replacement had a nice, quiet fan, but plenty of CPU whine. Still not ideal, but I was resigned to live with it.
This morning, I learned of the C2D update. Fortunately, every time the Apple Store in Ginza, Tokyo, issued me a replacement machine, they also issued me a new sales receipt. So, I took the replacement MacBook I got last week to the Apple Store today, showed them my receipt for the latest replacement (indicating that I was within the 14-day return period), and asked for an exchange. I had to pay the restocking fee, which amounted to about $150. The way I look at it, I paid Apple about a dollar a day for the last five months to "rent" their rev. A MacBooks until the rev. B's were released!
Needless to say, I'm a very satisfied customer right now.
Whisper-quiet, super-quick and brand-spankin' new!
Black Macbook; Mini 1.5GHz (Late 2005); PB Lombard: PB 2400; PowerMac G3;   Mac OS X (10.4.8)   Blueberry iMac; iPod nano 4GB; and a Bill King bobblehead doll--Holy Toledo!

i would like congratulate you and to share your jubilation!
i have also had three macbooks since they came out after my very reliable ibook was stolen. no end of problems with my macbooks and just send the last one back a couple of days ago. only to log on today and find they have 2 core duo's now. So ordered one straight away. now i cant wait to recieve it :o) but am scared of what problems these may come with

  • What to do with the CPU whine?

    I have a Core 2 Duo 2,16Ghz White Macbook bought a month ago. It has the infamous CPU (or logic board) whine - which Apple aknowledged on their MacBook Pro line. I have gone to the local Apple dealer where they said yes it whines but that Apple hasn't issued any orders as to what to do with the whine so try to put up with it... not very nice actually.
    The Macbook whine behaves almost identically to the Macbook Pro whine, so you can minimize it using PhotoBooth and some other programs. And using a Apple Might Mouse Bluetooth also takes the whine away (because the cpu is less idle).
    How can i get rid of the whine (high pitched noise-buzz)?

    I've seen quite a number of posts on the whine from various manufacturers. HP has actually posted a BIOS update to address the problem (at a significant cost to power management):
    http://h10025.www1.hp.com/ewfrf/wc/genericDocument?docname=c00965412&cc=us&dlc=e n&lc=en&jumpid=regR1002USEN
    As the MacBooks (and MacBook Pros) don't have a BIOS, Apple would have to push out an EFI firmware update. I would certainly prefer that if they go this route, they give you an option in preferences to either enable or disable the power saver features.
    Here is another comment referencing the whine other machines:
    http://forum.notebookreview.com/showthread.php?t=103747 (Toshiba, Sony, and HP)
    Unfortunately... I don't see any easy fix to this. I would imagine it is possible that some logic boards may exhibit the problem to greater or lesser degrees, but there would be no way to guarantee that replacing the logic board would result in a machine with less whine.

  • How come i only have the cpu whine when plugged in?

    Seems like most people have it on battery but I have it when running on power. its not to loud but if i am in a quiet room its kinda nerve racking. Like running your fingernails down a chalk board. i don't get it in XP so that means it must not be a hardware probelm.

    Richard,
    I tend to agree with you that this is a software issue in so much as it is rectified with a software solution.
    I get the whine only unplugged.
    However my Powerbook G4 would make the same whine only when running edonkey 2000. The same high pitched staccato whine would occur when that program was running. And the G4 was otherwise altogether free of whine.
    When I run the 'mirror' fix my CPU cycles get routinely as low as 1% 3% and I have a quiet machine. So whatever is fixing it is not using up a heap of processor cycles by any means.
    It should be easily fixed once Apple investigates what it is about the 'mirror' software that sorts this out.
    People who imagine that a company is going to recall thousands of machines for hardware fixes for a noise is dreaming when there's such a straightforward software fix.
    In that sense it's a software problem.

  • The CPU Whine

    Is it still present in the new models (week 23)?

    I had a Week 22 with almost-non-existant whine on AC, but a loud whine on Battery. This notebook I got it replaced because kernel panics.
    Next week I will receive the replacement, I gess it is going to be a week 24.

  • New Macbook CPU Whine? Wasn't this MBP only?

    I bought my updated macbook last week (Black, C2D 2.16 Ghz, 2GB Ram) and I noticed that the CPU whine that bothered me so much in my macbook pro is on my macbook as well!
    The photobooth trick works.. but I wish this could just be eliminated once and for all..
    Any suggestions? And does anyone else have it?

    I have covered this topic extensively for close to 1 year now. I've come to a conclusion that all MacBooks exhibit this problem to some degree. I've had my Logic Board exchanged in hopes to get rid of the problem - but no way - its still here.
    I've learned to deal with it in the following manner:
    1. I'm rarely in a completely quiet rooms - so in most cases I dont get bothered by the noise
    2. If I need to work in a quiet room - I use the Photobooth trick (force quit Photobooth - put comp to sleep - wake it up)
    3. I got Windows XP on bootcamp - I do most of my websurfing with the new Internet Explorer - and as most of you know - the CPU doesn't whine under Windows.
    The fact that CPU whine is completly eliminated when using Windows Xp means that the whole problem could be solved with a simple patch from Apple. However - Apple will not release any such patch until more people complain directly to them.

  • 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."

  • Core 2 Duo CPU whine.

    Hi everyone.
    I am close to purchasing a MacBook Core 2 Duo for my brother and I would just like to know how much of a difference there is in CPU whine between the Core Duo and Core 2 Duo MacBooks? Is the 'whine' in the C2D louder/more noticable or does it have less of an annoying noise?
    Thanks in advance
    Mark

    I got Core Duo - my girlfriend got Core2Duo and both have the CPU whine. There is no difference in between the two - they're not too loud but get little bit worse with time. Apparently not every MacBook has this problem - so my advice to you is go ahead and buy one - and if within 14 days you're not satisfied, have it replaced or return it for refund.
    Note that the CPU whine is not really that bad - that it will keep you from fully enjoying the computer. It only bothers me when I'm in dead silent room and browse the web. However - when I use Windows XP under bootcamp - there is no whine whatsoever. So when I need to browse the web - I do it on the windows side. Besides I really like the new internet explorer
    Good luck with your purchase. The macbooks are a great little notebooks. I doubt that your brother will ever complain about the CPU whine - even if it is present. My girlfriend has never noticed it.

  • 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.

  • 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.

  • 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

  • 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.

  • CPU whine/hum/sizzle

    I hope this is the right place to put this, I apologize in advance if it isn't. My computer has been doing a whining sizzle on the left side for several days now. It is loudest from the Q to R keys. This has done this in the past, but it went away pretty quick. Turning it off and restarting seemed to do the trick. However, this time it isn't going away. It seems to coincide with CDs or DVDs acting up - I have no idea if that's what caused it, but both times this started with a wonky disc; the first time, a scratched CD was inserted and I had trouble getting it out; this time I put a blank DVD in and my computer told me the disc was bad and to use a different one. Again, I don't know if that's just a coincedence, or what. The noise goes away when the computer is "thinking"...I took someone's advice (from these forums) and ran Photo Booth. That gets rid of the noise, but only because something is running non-stop, I'm assuming. Is there anyway to stop this? So far I haven't had much luck finding an answer! My software is currently all up-to-date. Thanks in advance!

    I also experience the CPU whine/sizzle when the CPU is idle. It happens when the CPU enters the C4 power mode.
    The utility ShhMBP (http://www.macupdate.com/info.php/id/22091) prevents the CPU from entering the C4 power mode and consequently stops the whine!
    The ShhMBP description says to use only on a MBP but it is safe to use on a MB. Enjoy the sound of silence, I know I am

  • 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.

  • CPU Whine Recording

    Further to what someone posted in another thread, you can actually record the CPU whine in Garageband! It is at a lower frequency than the whine I actually hear (the microphone need only sample at ~8kHz) but is very distinctive and clearly heard. It even changes frequency on chaning CPU usage.
    How this can be "within spec" is beyond me. Just thought I would record and post it before TNT pick up the laptop for refund on Monday.
    You can hear a demonstration recording of the whine here:
    http://ned.corpus.cam.ac.uk/~fjb31/
    James

    Yes, it's not great. I think that's an aberration of the sampling - although it could be due to OS scheduling of Garage Band.
    What is also interesting is that in the recording the whine is softer when the power cable is unplugged. To me the whine is much louder - this might be due to the sound being transmitted better through the case, or ears more sensitive to lower frequencies. From the recording you get the impression that both are of the same intensity.
    It would be interesting to record the sound at 44kHz find its true frequency and intensity and judge the human response to that - an oscilloscope trace would be good. It's not ideal recording the sound from within the case.
    One thing I haven't seen anyone comment on is the effect this has on using the MBP as a recording studio/for Podcasts etc. The background noise when both cores are on (and not heavily loaded) is sufficient to badly affect the quality of this.
