PowerPC :: Squeaking Or Scratching Noises / Noise Coming While Processor Works

Nov 2, 2007

I have a PowerBook G4 15" Laptop and it's recently started making a buzzing noise. It drives me crazy! The noise seems to come from the processor and happens whenever I'm scrolling through web pages, hovering over my dock, launching applications or pretty much whenever the computer is doing anything.

I've googled the issue and found it to be quite common, even being some posts on this forum. Here's the best info I've found so far:

"The squeaking is actually the processor going into Nap mode, and has been noticed on a number of G4 and G5 models. To save power when the processor has a little bit of idle time, it essentially turns itself off. What is happening when it's squeaking like this is it is alternating very rapidly between going in and out of Napping as the processor waits for more things to do. I've noticed that it happens most often during an active SSL connection; an https:// connection, Software Update, checking E-mail on a secure server, or any other secure connections can make this squeaking noise. There are many other ways to produce it too, such as scrolling through a web page or some other more graphic-intensive process.

If you want to check and/or get rid of it, you can download the CHUD tools (part of Apple's Developer Tools, and also available separately). The Processor preference pane (formerly called Hardware) will let you disable Napping, after which point the squeaking should go away. The squeaking also goes away if you reduce processor speed by turning Energy Saver processor performance down to Reduced. However, I'd recommend that you leave Napping enabled (to reduce heat output and increase battery life), so leave it in the default state."

I've downloaded the CHUD tools program and turned off Nap mode, I think. But it still makes the noises! I cannot figure out how to reduce processor speed. So frustrating. Anyone have any advice?

MacBook :: Scratching Noise Coming From Computer - How To Find Its Source

Nov 14, 2010

I have an aluminum macbook that is abou a year and a half old. It is making a weird scratching noise every few minutes. It sounds like I have DVD spinning in my disk drive and I am moving the laptop around. There is no disk in it so I am worried it's coming from my HD. Any ideas on what I should do?

MacBook :: Strange Noises After Installing Updates / Noise Coming From Fan?

Dec 21, 2010

I recently purchased a gently used MacBook. Running 10.5.8. The computer sounded and operating perfectly until I made the following software updates:

MAC OS X Update Combined
Security Update 2010-007
Remote Desktop Client Update
Airport Base Station Update
iLife Support
Java for Mac OS X 10.5 Update 5
Java for Mac OS X 10.5 Update 8
Airport Utility

Now I have an annoying hum noise, that could possibly be the fan.I have run Disk Utility, but the annoying hum noise remains. Does anyone have any suggestions before taking this by an Apple Store.This was intended as a Christmas gift for my wife. Can anyone spare me the embarassment?

OS X :: Strange Noises Coming From System / High Pitched Noise Near The Keyboard

Mar 27, 2009

I have a Macbrook Pro, one generation old. In the past week, it started making a high pitched noise from the upper left hand corner, near the keyboard. When I pick the computer up and change the angle, I can eliminate the noise.

Just in the past day I noticed that in addition to this high pitched noise, periodically a much louder, different noise comes from the same area, which again, if I move the computer around, I can minimize the noise.

My guess is that there is something loose in the computer, maybe a fan? Should I bring it to apple? My computer has been running pretty slow lately, could this have anything to do with it?

Mac Pro :: HDD Making Scratchy Squeaking Noises?

Jul 28, 2008

I have a PowerMac G4 with mirrored drive doors and just realized that my HDD (I think) is making these wierd scratchy squeaking noises. It might be my fan making them but I am not 100% sure. I am hoping that this doesn't mean the HDD is about to kick the bucket. Should I get a new HDD and ditch the old one? How would I go about swapping hard drives? I know there are issues with getting the new one to boot the comp n such.

PowerPC :: IBook Making Funky Noises / Mechanical Sound Coming From CD-Rom

Feb 28, 2007

but anytime someone pounds on the table and I have my 12' iBook just chilling on it, it makes a resetting noise, a very mechanical sound that makes it seem like it's resetting itself once. I have no idea why, and I just beg people around me to regulate their anger.

However, even when I am picking up my iBook it'll make the noise.Is this a sign of a deteorating cd-rom drive? Or are most iBooks and Apple laptops like this?

PowerPC :: How Can I Decrease The Noise Coming From My Emac?

Sep 18, 2007

How can I decrease the noise coming from my emac?

Sounds like a Jumbo jet taking off. Most of the noise sees to be more from the wooshing of the air through the vents rather than the fan.

I've vacuumed all the dust out of it (I bought it used).

Any ideas that don't require major surgery. I'm wondering if putting a new fan in would help? How much are new fans?

PowerPC :: Annoying Static Noise Coming From Powerbook

Dec 10, 2006

My Powerbook has been making a static-y sound from the back of it at random times. It sometimes won't do it all day, and then it will randomly start, and won't go away for a while. It's actually doing it right now! I've tried putting it to sleep for a few minutes, but it started back up again when i woke it up. There, it just stopped again! It can last from a few minutes to an hour, completely randomly! This problem started when I had Apple replace the logic board on the Powerbook a few months back, and numerous repairs later, nothing has changed, so I'm hoping someone here has an easy fix!

Sometimes I lift and carefully move my 17-inch MBP a short distance to another flat surface without putting it to sleep mode, it starts making really loud mechanical noise when I put it down, so loud that people in the same room can hear the noise and I can feel vibrations too! What causes this? Where does this noise come from? Is my MBP defective?

MacBook :: PISMO G3 Squealing Noise - Noise Coming From Under The Keyboard

Jul 14, 2008

Has anyone else had problems with an old G3 Pismo making an annoying squealing noise when plugged into a charger? There's a lot of noises mentioned in mac/apple forums but none of them relate to this one. Here's what it is not:

It's not coming from the screen or the fan or the speakers (it's under the keyboard). It's not low or slightly annoying (it is a loud squeal). It happens only when the power adaptor is plugged into the laptop.(it used to cease after I unplugged the power adaptor and plugged it back in three times; now that solution doesn't stop the noise anymore). It charges ok, and runs ok, scream or no-scream. It's quiet right now, but if I move the adaptor to another plug it will start again.

I was going to live with this, but today after an hour of operating quietly it just started again, and I hate to leave the house with this going.(it will scream whether the laptop is on or off. I have a really old battery and cannot replace it (I am currently staying in Mexico for the summer). Battery life is 45 min. I haven't tried pulling the battery out. That would be too easy.

This all started when I bought a replacement power adaptor (generic),after the original one melted down, but I could stop the screaming by unplugging/plugging it in again once or twice. Then I bought an expensive iGo adaptor, and it does the same thing.

I Did the PRAM and PMU reset.I can hear it over music or the tv. It grew lower in pitch today after squealing for a half hour. I'd normally not let it go on that long, but i was
in the other room.Is my PISMO dying?

MacBook Air :: High Pitched Whining Noises Coming From CPU?

Feb 1, 2009

I have a 1.86ghz 128GB SSD Rev B Macbook Air. The first one I had made a high pitch whining noise when the processor was idling or under light load. It was a very very high frequency noise, and you could only really hear it when the room was totally quiet - or unless you put your head near the top left side of the keyboard (where the CPU is located). A bit of googling and it seemed that older Macbook Pros also seemed to have had this exact problem.

I took it to the Apple Store and a Genius there took it back and said he could hear it as well. He offered to go through the repair process but since that would have taken awhile, I got an exchange instead from where I bought it from. Unfortunately, this new MBA also makes the same noise but to a slightly lesser degree (though it's possible that the frequency range isn't as high so it's not as piercing... hard to tell though).

Since this is my second RevB Macbook Air with the problem. I realize most people have lower noise sensitivity than me, so you might not notice it unless you place your ear to the top left of the keyboard. (And just to be clear, this is not a fan noise or a noise from the SSD - which don't make noises anyways. I am 100% sure this high pitched noise is coming from the CPU or somewhere on the logic board.)

MacBook Pro :: Hinge Making Squeaking Noise / Open Screen From Center Top Of Screen

My Macbook Pro is fairly new, and the hinge on both side is already making squeaking noise when I open my screen. It gets a bit annoying, I open it from the center top of the screen, not by the side. Is this a problem that I should be taking to the Apple Store? Or this can be fixed easily?

Mac Pro :: Trim Support Coming In OSX - Core I7 Processor?

Jun 14, 2010

Let's hope this happens for Mac Pro's as well.Here's the story on AppleInsider...Apple may be laying the foundation for TRIM support in future Macs, a technology that should allow their solid state flash drives to maintain optimal performance throughout the life span of the systems.The Mac maker's most recent 13-inch MacBook Pros display an option for TRIM support in their system profilers on SSD-equipped models, one which isn't present in either the second-generation unibody 15-inch MacBook Pros or the latest refresh sporting Intel's Core i5 and Core i7 processors.

MacBook Pro :: System Making Strange Noises / Noise Increase When Notebook Is Moved

Dec 25, 2010

I have a June 2010 17" 2.66 i7 UMBP. This is going to sound really silly and I do not really know how to describe it correctly, but it has begun to make lots of strange "Tapping/Clicking" noises. It happens quite regularly when the notebook is stationary but increase whenever the notebook is moved.

I am familiar with the hard drive clicking noise but this is totally different - it kind of sounds like a small metal ball-bearing inside a small, thin glass sphere knocking or clicking against it's side or like tapping a small thin glass object with something like a thin metal rod.

I am sorry for the poor description but that is the best way I can describe it & know I must sound like a complete idiot but I am not very savvy to computer issues but I hope someone can identify what these noises are if if they mean that something bad is going on.

OS X :: Weird Noises From Dragging Mouse + Emagic Sound Card Causing Noise

Dec 24, 2009

now what I have noticed is that the same monitors (speakers) i had with my older imac (24") are constantly making a louder "white noise" than what they used to (didnt bother me that much but i definitely noticed a louder volume of white noise). The thing that really bothers me is that whenever i scroll the mouse, or click and drag an object in photoshop or something the monitors are making a really noticeable disturbing scratching sound sound ...just cant seem to make it stop..its so annoying.. i also tried to record something and the imac recorded it in a really low volume and unstable wave (volume going up and down). so i figured well obivously the soundcard of the new imac was real bad..so got me an external soundcard, Emagic emi6|2m and i figured it would solve the problem. installed the soundcard, and played a song and suddenly a high pitch noise, kinda loud and really disturbing, started coming from the speakers.

2 seconds after i pauseded the song, the sound stopped. play the song, the noise comes, stop the song, noise stop after 2 seconds. if i open up Logic, the sound just starts no matter what. quit Logic and the sound stops. just now i opened up a youtube video and the sound just started going off even after i paused the video. now the sound comes everytime i choose the Emagic soundcard in the sound preferences. its kinda real loud and its bothering me so much, i cant seem to make it go away and definitely cant work with it. When i tried installing the soundcard on my brother's laptop windows with the same speakers, everything was fine and it played perfect with no noise. whaaaaat can i possibly do, this actually really frustrates me.... whats wrong with the computer? something with electricity?

Mac Pro :: Weird Noise Coming From Speakers

Apr 16, 2009

I noticed in the past week that when I scroll through a webpage I can hear a clicking sound (similar to the one from the MM) coming out of my speakers? This also seems to happen when I scroll through my iTunes library but in this case it's a humming sound, when the scrolling stops so does the noise. I've tried muting the speakers but the sound is still there, has anyone else experience this before?

MacBook Pro :: Plink Noise Coming From New 2.2 System

Mar 2, 2008

Just got a new 2.2 MBP delivered to me yesterday. Didn't seem to have any problems at all until about an hour ago. I just began hearing a metallic "plink" noise every few minutes or so. Its not a click or a tick but more like a hollow plink. It comes at random intervals but sounds like it may be coming when the hard drive(?) or something inside the machine spins.

MacBook Pro :: MBP 2009 - Clunk Noise Coming From HD

Oct 12, 2009

I bought a MBP 15 inch 2.66ghz brand new back in september. Since my purchase i have has several things that have been annoying the crap out of me.


1. Clunk noise coming from HD, I have read some posts and installed Hdapm which reduced the sound a bit (i have the 320gb 5400rpm Fujitsu)

2. I believe becuz of the clunking (parking of the heads) causes my computer to stutter (mini freeze for like 1-2 secs) while using my MBP..

3. The battery used notify me that i had PLENTY of time to use even when i had below 50% battery life left, now (on Firmware 1.6) the battery tells me i usually have like 2:30mins of use when im at 85% or so battery strength left. and YES the screen is dimmed along with the keys.(i have calibrated the battery also)

I went back to 1.6 firmware due to the notion that various people have had better success on their harddrives working "better" with stock, or aftermarket.

I am on a CLEAN install of Snow Leopard...

Mac Pro :: Rattling Noise Coming From Lower Intake Fan

Aug 6, 2010

Well, this problem that I thought was coming from the Radeon 4870 fan was really coming from the lower intake fan on my Mac Pro. The rattling noise was coming from this fan itself, and the Radeon 4870 was actually running silent the whole time. This is probably why people with the X1900 and older Mac Pros have been reporting the same issue. This has actually solved the problem for me, my Mac Pro is running silent now: I downloaded SMC Fan Control, then I increased the speed on my intake fan to max, 2800rpm. I let the fan run at max for one minute, I had an idea that this would cause the fan to work out the kinks if it had any. Then I returned the fan speed to normal, and the problem has been gone for the past 15 minutes. You can download SMC Fan Control 2.2.2 (Snow Leopard compatible) here: [URL]
