MacBook Pro :: 13" CPU Whine Driving
Oct 23, 2009
Is anyone else experiencing a very annoying electrical noise or whine coming from their 13" unibody pro? Mine is about a month old and has gone from very quiet to so annoying I have to play music sometimes to not hear it. It only seems to happen when the charger is plugged in and the computer is idling. If I open a program it gets quiet while loading. If I just move the mouse around the screen, however, it gets very loud! I don't know what to do. I'm a couple hours from the nearest Apple store and if I make the drive I have a feeling they wont be able to hear the noise in the store.

Running a 23" Cinema Display from my Macbook Pro (Lion 10.7.3)I'm noticing that the laptop is running a fair bit hotter than before, with fans kicking in from time to time when I'm pushing Logic to the limits.

I originally purchased a SR MBP a couple weeks ago and come to find out, the LCD was bad and Apple declared it DOA. I went to the Apple store and swapped it out for a new 2.4GHz Penryn MBP. I am running Vista via bootcamp and am noticing a high pitched whine coming from the top left hand side of the keyboard, near the LCD. Puzzled as to the cause, I started playing with some controls to see if anything made a difference and noticed that when I dim the LCD to the min, it almost goes away. When I turn off the LCD it does in fact go away and when I increase it to maximum brightness it also vanishes. The noise seems to be the loudest when the LCD brightness is set in the middle. This problem only occurs in Vista, not OSX. I thoroughly toyed with the brightness in OSX and listed carefully, but like I said, not noise is present.
Should I be concerned and call Apple, or just ride it out? It does bother me a bit considering I use Vista for Office 2007 tasks. However, since the problem only occurs in Vista and not OSX, it this indicative of a software issue, or do you guys think it is hardware related? cmm26red

I bought my maxed-out MBA (2010) online the day after they came out and have recently noticed a CPU whine coming from the top-right corner of the keyboard when under light load. It can be heard both on AC and battery power and is distracting when using the Air in a quiet room.

I have a less than 1 month old White MB. I have become aware of an electronic noise emanating from below the upper left portion of the keyboard, under the q,w,e keys. The noise can be best described as a mechanical mosquito; it is a constant high-pitched buzz that starts once the computer has fully booted up, and doesn't stop until it has been shut down. Although it is quiet, if you get your head anywhere near the keyboard it is readily apparent and obnoxious. It does NOT appear to be fan related, as I can hear those going as well. I have listened to other Mac laptops with equal scrutiny, and this noise is not present.
A simple Google or Apple forum search indicates that people have been noticing this problem for years. Indeed Apple appears to have acknowledged it recently with MB Pros: (URL) I believe it indicates a faulty logic board.
- Have others noticed this with their MBs or MBPs?
- Does anyone know the true source?
- Most importantly can anyone give me some tips with how to deal with Apple on this?
They have suggested I go talk to the store I bought it from. Those guys claim not to hear it (a common theme from what I have read). However, this is highly dependent on the level of ambient noise and hearing ability of the individual. I already had to return one MB that was DOA, and now I have this one. Given the expense of this purchase and the age of the machine I feel that I am entitled to a new one that does not display these issues. How can I effectively communicate this to Apple or my retailer, neither of which will likely want to comply?

For a while now, I've been getting a strange whine out of my mbp core duo right above the power button. I don't believe it's the common "whine" others have complained about as I've tried brightening the screen/turning on the camera. Tapping on the case will stop the sound for a bit, but it soon returns. The sound comes and goes, but in incredibly irritating.
I have a sample here. You may need to turn up the volume to hear it. Yesterday I replaced the right side fan, but the sound is back. Now I'm thinking it's the speaker, but don't want to spend more money on parts unless I'm relatively confident of the problem.

I've heard of people having issues with high pitched whining coming from the left-side of the keyboard due to the backlight inverter. There isnt much that can be done about it from what i've seen. My issue is slightly different, as I get the high pitched whine nearly at all times, and it changes dependent on the angle of the screen and level of backlight brightness.The biggest problem is that at certain points where the whining is happening, everything on-screen will freeze until Ive messed with the screen angle and played with the backlight buttons, then as soon as i've done that, it almost 'snaps out of it' and things on screen start happening again.

I know this happened before in the old Macbook Pros by the look of things when I searched around.Basically there is a noticeable high pitched whine when the screen brightness is either not completely off or max.

Hey guys, got a little issue here. I have had a MBA since about march of this year. Just recently I on two occasions the computer has all of a sudden had this loud high pitch whine. It has only happened twice and at both times (if I remember the 1st time correctly) I wasn't really doing anything on the computer. Today specifically it was just sitting idle on my desk. Not sure where its coming from maybe speakers? Any idea to what this is? Should I be setting up an appointment to see a Mac Genius?

This is my first post, and I apologize as it's a little long. I just wanted to get the whole story on the table and clarified.I've had one of the new Aluminum 13" MacBooks (2.0GHz C2D) since Christmas Eve. A few weeks ago, it accidentally fell off my desk at work (not a far drop , but far enough for my heart to stop for a few minutes) when I got tripped up in the power cord under the desk.
For all intents and purposes, the MacBok seemed to work fine. I had one of our IT staff, who happened to be a trained Apple repair tech, take a look at it; the only real damage was that the display hinge had been knocked a little out of alignment. Just ot be on the safe side, I took the machine to the Apple Store, where they told me not to worry about attempting to get the hinge fixed (because I'd be paying a lot of money for such minor work), and the Genius sold me a hardcover plastic Speck case for the MacBook.
While the Speck case certainly looked nice and madethe already sturdy laptop feel sturdier and "protected", I was a little concerned about the amount of heat the machine was giving off within the case. On Sunday, I unplugged the machine from the MagSafe charger for a few hours and left it closed in sleep mode. When I woke it back up, the fan on the left continually gave off some sort of high-pitched whine whenever the computer was in idle mode.
I Googled, searching this site and others, and read about the "CPU whine" in the previous generation MacBooks and MacBook Pros. I also saw where a few people with new Aluminum MacBooks were having this same issue or something similar:
URL
It seems to only make the noise when the computer is running off of the battery - plugging in the MagSafe charger makes the noise quiet 85% of the time (I've found that plugging, unplugging, and replugging will not stop the whine from occurring).
I tried installing QuietMBP as was recommended in some posts, but the only setting that will stop the computer from whining is the "highest" setting (that is, allowing the processor 0 seconds of idle time), which causes QuietMBP to eat up 30% of my processor usage in Activity Monitor and to start the fans going (and, presumably, to significantly lower my battery life).
I don't know whether all of this was the result of the MacBook falling, from it overheating in the case, or something that "just happened". I set up an appointment with the Genius bar for today at 4 PM, but Idiscovered another odd occurance when I set up a new account for the Apple Store (rather than give them my password)
The noise never happened under the new account. Never. I left the machine idle until any and all initial processes were done. No noise. I checked Activity Monitor for stray processes. None. And no noise.
Now I'm bewildered. Could something have gone wrong somewhere in my account, leading to a corruption of a power management utility or process? I'm not canceling my appointment, but I am going to try a few things before I leave. I've already repaired disk permissions, and I'm about ot reinstall the 10.5.6 OS X combo update. Should I try to reset the PRAM too? What other options should I be looking at?
Or should I just wait, and let the Genius Bar folks look into it? As a note, I'm aware I may have to pay for any repairs because they may or may not blame them on the MacBook having dropped (despite two to three weeks passing between the fall and this issue arising), and I'm okay with paying for reapirs (though I will try my best to argue my case, of course).

I have a 1.8ghz G5 iMac with ambient light sensor. When it is on there is a noticeable high pitched whine that is quite loud. It gets even louder if the fan runs more.
If I replaced the fan would this solve the problem or could it be the power supply?

I have been presented with an iMac G3 400Mhz. It has an annoying loud whine. The whine is constant and high pitched. I am thinking exhaust fan. Is my thinking correct? Is it hard to get to and replace?

So last December my laptop got smashed and everything works except for the backlit screen. In fact I can still use this laptop it is just extremely hard since the screen does not light up. The person that smashed it ended up buying me a new laptop so I have this beat up (and I mean the shell is destroyed) laptop with quite a lot of functioning parts.
Now a few weeks ago my girlfriends Grandad spilled a beer on his brand new 2010 Macbook. The logic board is shot so it is almost cheaper for him to buy a brand new laptop.
Would it be possible for me to take the logic board out of my 2008 Black Macbook and put it into his 2010 White Macbook?

By far the most interesting benchmark trend coming out of the latest Macbook Air tests is that of the 320M GPU - is this thing somehow clocked differently than in the Macbook/Macbook Pro?
From:
[URL]
The latest Macbook Pro 13" 2.4 Ghz gets 33 FPS in Call of Duty 4, whereas the Macbook Air 13" (using the same 320M GPU) gets 40 FPS. Even the 1.4Ghz 11" gets 37! So obviously we're not talking about a CPU limited game - the only explanation then is that the GPU in the Macbook Air is clocked differently than in the 13" Macbook Pro, no?
From:
[URL]
Again the Macbook Air clocked at 2.13 ghz is beating the 2.4 Ghz Macbook Pro in World of Warcraft and Portal! And in WOW the 11" 1.4ghz still manages to beat the 2.4 Ghz 13" Macbook Pro.
Anyone have any additional insight into this? Anand did a terrible job of testing these for gaming performance, unfortunately, so he may not have even noticed this trend.

Is the white one the same size as the 13" aluminum that now went pro?Pretty much, I want to know if I buy a case for the original 13" Metal uMB from InCase, will it fit on this plastic one? They don't have blue for this, but they have blue for the original aluminum one.

I have a 2008 13" white, plastic MacBook. Its a bit slow, but adequate. Thinking of selling it and paying the difference to get the 11" MacBook Air. I've heard it is similar in speed and has the same processor.
The main problem I have with my current MacBook is that its heavy - I need something lightweight to easily carry to school and class for note-taking and such.
How is the Air better or worse, and would I be losing anything significantly by replacing the 08 plastic MB with a MBA?

I just upgraded my daughter from last year's MacBook to a new 2009 MacBook Pro (my mother will get her old one) by cloning the drive using SuperDuper. Everything works fine except it doesn't detect the audio hardware in the OS. I see that the new macbook pro has different audio hardware according to system profiler. Is there a way to copy the driver off the install DVD or should I just go ahead and reinstall everything.

Have searched on Mroogle but couldnt find what i was looking for.
I have my Blackbook connected to my tv via mini dvi to dvi then to hdmi, but i also have another laptop which is the old style Macbook Pro.
I was looking for a piece of software that would let me use the other laptop which isnt connected to the tv as a wireless keyboard and mouse?
Anyone ever tried this before? Any ideas?

I just bought a macbook as a replace for my five year old iBook. I was planning on purchasing a second power adapter. I like the size and more rugged connector on the Macbook Air power adapter.
I have searched around and it sounds like the Air adapter will work with a MacBook but I am not completely convinced. I understand that this adapter will only charge or power the unit but not both.
Has anyone tried their Air adapter on a MacBook? Could an Air owner tell me the voltage and current rating (outputs) on their adapter?

I wanted to know if I can replace the upper case of a Core Duo white macbook with that of a Core 2 Duo black macbook? The white one has the distinctive yellowing of the rev A macbooks, so i'd like to make it better whilst making a black/white frankenMac.
If not, can I at least replace the airport card?

I'm putting a computer in my kitchen that anybody in the house can use (kids & parents). It will be hooked up to a 24" LCD and also act as a small file server, dvd player and perhaps eyetv dvr.
I like the mini because it is small (can hide in the cabinet where spills won't get it), is cheap and uses only 13W when idle. But when I think down the road, 4 year old laptops seem a lot more useful than 4 year old mac minis. So I'm a bit torn.
So my questions are:
- Does anybody know how much power the macbook uses when "idle" (just running finder).
- Can the macbook be run with the lid closed? (I know old powerbooks used to vent hot air through the keyboard.)
(Then again, I have the computer in the kitchen so I can watch my kids on the computer. In 4 years they'll be 5 years old and probably want a laptop they could have in their own room - exactly what I want to avoid. And I'll probably upgrade my macbook pro by then anyway.)

I have a late 2009, white unibody MacBook which is 7 months old, and I have been noticing that the battery life is getting less and less, and am rather confused.I reset the SMC as per Apple instructions, and then followed the battery calibrating guide to the letter from apple.com, and tonight it seems to have lasted... 3.5 hrs! Hardly the quoted 7 hours that Apple spec, and I am simply doing light web browsing, nothing else.Am I doing something wrong? The machine sits connected to magsafe 90% of the time, but I cannot envisage that would cause any problem, as it knows when it is charged, so afaik no more current can get to the battery to damage it
