Mac Pro :: Slight Buzzing Noise Around Power Socket

Nov 2, 2008

The power socket at the back of the mac pro makes a kind of buzzing noise. Only for a short amount of time though. I have have never heard this before as it isnt that loud at all, and only cam across it by chance. I kind of figured out that it might be the electrical current.

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 :: Clicking Noise When Slight Pressure Applied Near (not Just On) Trackpad

Jun 1, 2014

I just bought a refurbished Macbook Pro and after less than a week, I've just started detecting a sort of soft clicking noise when my palms make soft contact with the area near the trackpad. It's not the trackpad clicking, which is a distinct noise.

Mac Pro :: Mac Pro Buzzing Fan And Hard Drive Noise?

Sep 1, 2006

I received my nice new Mac Pro yesterday. 2.66GHz With one 160gb drive and one 500gb drive and some other customisations which, for the purpose of this are not relivent.

My first and most serious problem is a rhythmic clicking, which according to technical support is a known issue and is to do with my hard disk drive. The noise comes from the top front side of the machine and clicks at around 200bpm at all times. It is very audible and unnexceptable and for this reason Apple are replacing my machine.

The second problem which I believe to be more of a design flaw is noisy fans. I obviously know fans make noise but this is an intermitent buzz, at a constant frequency. It sounds like a bee is flying about in my machine and varies according to the angle of the machine and wheither the superdrive bay is open.

As you will understand I am very dissatisfied. My machine took 3 weeks to arrive and is riddled with problems.

MacBook :: Fan Making Buzzing Noise

Jul 22, 2009

I 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?

MacBook Air :: Fan Making Constant Buzzing Noise

Mar 16, 2008

I 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.

IMac :: 24' Hard Drive Fan Buzzing Noise?

May 25, 2010

I've owned my iMac for a little over a year and I started having a weird buzzing noise coming from a hard drive fan. Downloaded iStat, everything runs at idle speeds (hard drive fan at 1200rpm), so the speed is not an issue. Sounds like a mechanical problem. Also downloaded FanControl, and once I increase the fan's speed to 2500rpm, the buzzing noise goes away, but now I can hear the fan It kind of defeats the purpose of having the expensive computer, that used to be virtually silent. I am in remote location in Alaska, where we don't have Apple store and the only way to fix is to ship it to mainland. Apple warranty is over, but I still get additional 1 year of coverage from Amex credit card, but I would much rather prefer to to fix it myself. Any suggestions on possibly replacing the fan myself? I am really debating whether I should ship it to Apple and trying to go through American Express with warranty. That would be complicated and I would end up without a computer for a few weeks.

MacBook Pro :: Making Humming/buzzing Noise?

Apr 4, 2012

Yesterday 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?

IMac :: When 27" In Sleep Mode Or Turned Off/slight Crackling Electrical Noise?

May 4, 2010

When 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.

Laptops :: MacBook Pro Grinding/buzzing Noise - How To Avoid It

Oct 5, 2009

Let me preface this by saying I am probably taking this to the Apple Store about an hour away from where I live tomorrow. For A while my MacBook Pro 13" has been making a loud spinning/grinding noise on occasion. Normally, I'd just shut down, boot up, and it would be fixed. Well, yesterday, that didn't work. After being told by the support guy that my free phone support expired 14 days ago (Mac bought in June), he said he'd do what he could to help. I told him about the noise and held the phone up to it (it is coming from the right of the trackpad). He said he had never heard that before and said to take it in to the Apple Store. I've found an Apple Support article, but it doesn't shed a lot of light on the situation.

MacBook Air :: Constantly Making Buzzing / Whirring Noise

May 12, 2008

I'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.

Applications :: Recording With QuickTime - Continuous Buzzing Noise?

May 16, 2009

I've been trying to audio record my piano playing with my unibody Macbook using Quicktime Pro 7. The recording is absolutely terrible--there is so much buzz, as if the microphone is being held right next to the back of the piano. In truth, I set my laptop about ten metres from the piano. The buzzing continues. It's as if the equalizer settings are set to max.

MacBook :: Screen Brightness Related Buzzing Noise

Jun 1, 2009

Ever since the 10.5.7 update I've been getting issues with my macbook, this a new one. I've looked around google for any other similar incidents and there have been but none with a solution so I figured I would ask here. At random times my screen starts making noise, I say my screen because if I dim the brightness to zero it stops, and the brighter I get the higher the pitch, the lower brightness - lower pitch.

Intel Mac :: Making Constant Buzzing/humming Noise?

May 6, 2012

I purchased a 21" iMac a couple of months ago. Today it started making constant buzzing/humming noise. It's not really loud, but it is noticeable and annoying after a while. It stops if I put the computer in sleep mode or turn it off, but it starts back up  the moment I turn it back on again. It sounds like it is coming from the bottom of the screen near the speakers. I have tried adjusting the brightness and volume, but to no avail. I also tried lifting the computer off the desk to see if it was just vibration, but that did not make a difference either.

Intel Mac :: Buzzing Noise Coming Out Of Cooling Vent

May 23, 2012

I have noticed this buzzing noise (like crackling electricity of sorts) coming from the left side of the machine out of the cooling vent. I bought my IMac in 2010 and have not had any problems with it until now. I noticed the "noise" a couple of months back and it would show up here and there every once in a while, it was not annoying, so I let it be. Until this last time, when the noise was loud and annoying, I could not just forget about it. I am under warranty and called into Apple to see what can be done for this problem.

OS X :: External Hard Drive Makes Buzzing Noise/ Not Reconized By Mac?

Mar 8, 2010

I've got a serious issue that needs to be solved, one way or another. I have a Seagate FreeAgent 1.5 TB External Hard Drive with two partitions on it: one for Time Machine, and one for extra storage. Yesterday, I tried to plug the drive in and nothing happened. It didn't light up; it wasn't recognized by my Mac. Just a strange buzzing noise that occurs every 2-3 seconds. So, I left it alone overnight. Woke up this morning, plugged it in, and same results.

I'm extremely upset and concerned over this. Losing this data is not an option, as there are more than just backups on this. It should be noted that the day before this started, it took a short tumble off my desk, and when trying to eject it yesterday, the drives would not eject so I had to pull it out. Please, if you know of any way to get it working again or to salvage the data on this thing, please help. I've attached an audio clip of what the drive sounds like when plugged in.

My 20.5 inch 2.7GHz iMac is about a year old and has recently started making a low humming/buzzing noise from the top right corner, near the SuperDrive bay. The top of hte iMac feels quite warm when it makes the noise and usually stops if I hold my hand on top of the computer. Is this something I should be contacting AppleCare about?

PowerPC :: 15" Powerbook Suddenly Making Loud Buzzing Noise And Crashing?

Feb 28, 2008

I have an older 15" powerbook Titanium. About five years old now. Been working pretty well all five years, save for an external hinge I had to replace. Last night, the computer started buzzing from the insides, a buzzing reminiscent of a distant chainsaw. The program i was working in (firefox) just went to the pinwheel of doom and never recovered. I moved to the finder, which did the same. I forced booted. Same noise. Same problems. I can use programs for a few minutes, but then they pinwheel of doom and the computer freezes out.

PowerPC :: Power Cable Plug Socket Pulled Off Inside Powerbook?

Oct 29, 2005

so today was the day to replace the broken harddrive inside my 12" Al Powerbook and naturally I've ballsed it up.

The problem came at this stage of pbfixit's instructions. In pulling the power cable out of it's socket, I've pulled the bloody socket off the board.

So this is bad, that much is clear, and I need help, and lots of it. What's the best course of action now? It's not under warranty or anything, it was second hand to begin with.

For what it's worth, if anybody else finds this while searching for dismantling instructions, it's actually not too difficult. I would change this section of the instructions though, as I'm sure it'd be easier to lift up the top case slightly and then disconnect these two cables rather than fiddling through the tiny holes. I think going in that way give you a side angle and more opportunity to grip properly. And less opportunity to break your Powerbook. Anyhoo...

Power Mac G5 :: Loud Fan Noise On Start Up?

Nov 18, 2007

My G5 has been making more noise at start up. It sounds like one of the fans is making a grinding "rrrrrrhhhh" noise. My living space if very cold and quite dusty (warehouse). I notice it more on colder mornings ( inside temp 45° - 65°F ). Should I refrain from using my machine on cold mornings/nights until the heat is running?

Mac :: IMac 27 - I5 Vs I7 Heat Noise & Power - 1200VA UPS

Jun 4, 2010

I am almost 100% that an iMac 27 is my target, (not quite discounted the MP but lack of remote without extra is actually a big factor).I would prefer the internal HDD bays and such forth, but I've had a MP before and as I have some ext FW its not a deal buster. The imac looks stunning, has simplicity and a nice big screen.My only real questions are (with it being on top of the desk); what's the noise and heat like for the i5 and i7 models? I'd like to get thoughts on both.For my uses an i5 has enough oomph, but the i7 would be nice (just speed up those transcodes etc).Is there a huge difference in the power draw on these machines (I have a 1200VA UPS).

Power Mac G5 :: Only Hissing/licking Noise From Digital Audio In?

Nov 2, 2007

I am trying to hook up the digital audio output on my cable box to the digital in on my dual 2.0 G5 running 10.4.9, 1 gig RAM. I have HDMI and component video out to monitor, but I use JBL creature speakers and sub for audio.

I have the propper cables and routing, sounds prefs set to digital in, and line out, to go to JBL creatures and first I get no sound at all. If I start AudioHijack and use same input and output settings all I can get is a hissing/clicking sort of sound. Same with using Soundsource and LineIn.

Audio MIDI Setup only shows or giveds me Built-in Audio for selections under system settings and properties for. Ausio Input and output show Master stream grayed out and I selected digital in and Line out for my sources and no change. Both ar set to 441000.0 Hz 2ch-24bit as well.
