MacBook Air :: System Making A Strange Noise / Loud High Pitch Whine
Jun 18, 2008Hey 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?

Dec 20, 2010I just got my 2.0ghz Alu Macbook a few days ago and everything works perfectly well, the thing is that after day one the magsafe started to emit a low pitched electrical whistling noise. It tends to be there a few minutes after booting into the OS and then it turns down to almost unhearable, but I experienced it returning after a few hours of use and then disappearing again. If I move close to the escape key I can hear a crackling noise emitting from the magsafe.I'm not trying to be overly nitpicky or anything but I read somewhere that if it's doing that it would be a faulty Mag-Safe board or something.
Does any one you guys know anything about this? I have the 14 days to return it as I bought it online from the Apple Store so if it's a faulty part that might die/break/ cause problems later I might have to.
MacBook :: Left Fan Giving High-pitched Whine / Noise Coming When Computer Is Running Off Battery
Dec 26, 2010This 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).
Mac Pro :: Does Your 2008 MP Give A Slight Electrical Humming Noise?
Apr 14, 2009..by the power unit at the back of the machine - where the power cord goes in.
I happened to be switching out displays at the back of my MP today. Could hear the fan at the lower back portion of the machine (as normal). but this time could also hear a very slight electrical hum just by the power unit -- is this normal (the hum) does yours have this hum?
I never heard it before. guess my head was never that close to it when the MP was on the floor. but since i moved it to the top of the desk my head is closer to it when I switch out the DVI ports
Trying not to be obsessive. I'll run before the white coats turn up by the front door
MacBook Pro :: System Making Mechanical Noise / Noise Before Start Up Sound
Dec 26, 2010My first generation unibody Macbook hasn't had any problems to this date but now it's constantly making that mechanical loading-like noise which is usually heard when the Macbook is switched on (the noise before the start up sound) or when the lid is opened to wake up the computer. Is there a fix to this?

May 4, 2010When the computer is sleeping or if I turn it off but the plug remains in the electrical socket, when I get very close to the machine I hear a slight crackling noise, as if the internal adaptor is making a slight noise. I don't hear it from any normal distance, and other than the buzzing phenomenon when brightness is below 50%, no other symptom. Is this normal for this model. I believe that the external adaptor for the 30" ACD made a louder but similar noise as well unless unpluged.

Jul 22, 2009I was just downstairs in my basement using my macbook and I decided to come upstairs and when I got up here I noticed that my fan is making a weird buzzing noise. I can tell it is my fan because when I make the fans spin faster in smcfancontrol the noise gets louder. Could this be something that is in the fan or could this be a more serious problem? I can take the back case off and check but I just wanted to know if this could be a serious problem with the fan. Is there any chance I could have bent something by carrying it wrong?

Apr 11, 2012My MacBook Pro just started to making a clicking/ticking noise. I am assuming that it has something to do with the fan because when I shut my computer down, the noise stops, but once I start my computer back it, it starts once again.

MacBook Pro :: Making Ping Noise - On Or Off

MacBook Air :: Fan Making Constant Buzzing Noise
Mar 16, 2008I have had my MBA for almost a week, and I've had no issues so far. Until now. This is the case: The fan operates as it should. It stays on 2500 rpm at light use, and increases with heavier use. At 2500 rpm I was not able to hear it without putting my ear next to the keyboard. That was yesterday. Today the fan produces a new noise. It isn't very loud, but clearly audible at 2500 rpm in a quiet environment. It's a low, constant, buzzing kind of noise. It also increases with fan speed.

Jul 4, 2010I have a 13" MacBook Pro from Mid-2009 and just today I've noticed a real faint clicking noise coming from the fan. It almost sounds like that noise a bike makes when you put a baseball card against its wheel. It's not very loud, but when I'm working in a silent room, it's been pretty annoying. I opened the back and blew all the dust out and all that, but the problem seems to only have got worse since then. The fan is still spinning at its usual 2000rpm.

MacBook Pro :: Making Humming/buzzing Noise?
Apr 4, 2012Yesterday I started up my MacBook Pro that I've only had for about 9 months. I immediately noticed that there was a barely audible buzzing / humming sound coming the inside of the laptop, most likely in the fans. I don't know how long this has been going on, and I really don't know the cause of it. So is this something I should be worried about (the sound is barely audible)? Or is this something that happens after prolonged use of the laptop?

Sep 29, 2010I purchased a MacBook 2010 from bestbuy almost two weeks ago, I have only really internet surfed and added some songs from my ipod using senuti. Yesterday I started noticing this little noise sort of a sounds like a bug like a scratchy hiss (or something spinning kind of like the noise my ipod classic makes every now n then) its very quick but it happens every few seconds. Now mind you it is very faint cant hear it if there's noise around me but if its silent I can hear it. I wanted to know am if its something I should be concerned with or was this small noise there from the beginning and i just started paying attention.
View 6 Replies View RelatedMacBook Air :: Apple Tech Making The Screeching Noise?
Mar 19, 2008I called Apple tech support about the screeching noise I started hearing more than once out of my Air. This was posted by someone else and there is a youtube video floating around also. I am going to take it to the Apple store to have them look at it, but I also asked the rep about operating temp range.
He said that spikes up to 90 degrees are normal, but if it startes to climb or stay in the 90-100 range, then someone should take a look at it.
Not sure how reliable this is, but thought I would mention it.
MacBook Air :: Constantly Making Buzzing / Whirring Noise
May 12, 2008I've had my Macbook Air 1.8GHz SSD since basically the day it was announced and aside from iChat video lag and YouTube (which has only happened lately), it's been almost perfect. One of the things I particularly loved about it was how silent it was, but as of Saturday, that suddenly changed. It now makings a constant (as in, never stops as long as the Air is on) noise which sounds like a harddrive being accessed; a kind of buzzing/whirring noise. It's not particularly loud, and once about 2ft away you can no longer hear it, but it is concerning that it would suddenly start.

Apr 4, 2010I have a 2009 15" Macbook Unibody and for as long as I can remember the superdrive has been making a loud noise when I boot up the machine. Its similar to the noise when you insert a disk. I just figured this was the lens aligning and that it was normal. My brother however works at an Apple store and has a Unibody and his is deadly silent, he also said the laptops he had used at work make no such sound. He said as long as the drive functions then its nothing to worry about.
It doesn't happen at any other time, and the drive does indeed function perfectly fine. It just bugs me when I turn my laptop on and hear a loud freaky noise. Just wondering if anyone here has this and what they think of it?
