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!

I have a Macbook Pro MC666ll/a. It is a core i7 15" with the AG screen. The issue I am experiencing is a random static noise coming from my speakers every now and then. If i have external speakers plugged in then the sound comes from the external speakers. Is this normal?

My mac has worked great for the last 2 years since ive owned it and it just started to act a lil differently about 2 weeks ago. I started to notice that it started to act a lil slower than normal when i was surfing the internet. Then a couple of days ago the computer started making like a buzzing noise , kinda sounds like interference . Like when a cell phone gets close to a stereo system. Sometimes the noise will go away and then when i start opening diff app. that use computer cpu the noise happens again. It was just making the noise and i was dealing with it until the computer started to crash. It would look like the screen was on fire and everything would just freeze. Do you guys think it is the hardrive ?????? and if it was what would be my best option for fixing this. Can i save the stuff that is on my current drive ?? I have a bunch of stuff that is very important on this hardrive.
whats the best place to buy a hardrive if i need one ? and can i buy a hardrive that can hold more than the stock 74.53 toshiba MK8025GAS ?

What is going on? Anyone ever experience this? I have the volume turned all the way up, it's not muted, but I am getting no sound. I have had this happen before, but a reboot seemed to fix it in the past. It's been like this for a few days now.
any ideas?

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?

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?

I just purchased some logitech 2.1 speakers for my Macbook Pro, and unfortanetly, there is a pretty noticeable hum or buzz coming from the speakers. When I have the volume for the speakers turned all the way up, and the volume on my computer on mute, it's most loud. It's quite annoying.
I feel like I had this problem with my previous speakers (without a subwoofer) but I resolved it somehow...What to do, what to do...

The machine I'm having trouble with is a Powerbook G4 17" 1.33GHz with 2GB RAM. This machine has been very well cared for. It's mostly been used as a backup machine of late. When I do need to take it out with me, it's transported in a InCase padded Napa leather case.I mostly use it plugged into AC, and when I have it plugged in for longer than 24h, I remove the battery.
It is running for the most part of the day when in use. And when it is in use, it rests on a Cooler Master fan cooler pad to help with the cooling. I just close the lid when I'm done with it. The only time that it is shutdown or rebooted is when an update or installation requires.
So recently I brought it along to a friend's place, and she borrowed the machine to browse the internet. Being unfamiliar with the sleep function, she shut it down. After this, I cannot get it to start up again. Some of the measures I've taken to try and revive it are:
1. Resetting the PMU (shift-ctrl-option-power, wait 5s, start).
2. Removing AC + battery and holding power for 10s.
3. Reseating the RAM (swapping slots, removing one stick at a time, replacing the RAM with the original 512MB stick).
After all this, I still get nothing. I mean nothing. No chime. No grey screen. No spinning gear. No latch light. No fan. No whirrl-clunk from SD. When I say nothing, I want you understand I'm getting absolutely nothing.
There is a weird thing though. The battery indicator (5 LEDs on bottom of the battery) work. The AC ring indicate fully charged (green ring) and charging (orange ring). With the AC ring indicating charging (orange ring), and I invoke the PMU reset, it momentarily turns green before resuming on orange.
I've tried looking high and low for anyone with remotely the same problem, and can't seem to find anything like this.As far as I can tell, I think it's either a logic board failure or a PRAM battery failure.

I have an early 2008 Mac Pro with an EVGA 8800 GT installed. When I bought the computer the EVGA 8800 GT was almost silent even when under max load.
Now 15 months later the EVGA 8800 GT fan is making so much high pitch noise under load that I try not to use it for heavy 3d. The noises started after about 6 months after purchasing.
Monitoring the fan speed under Rivatuner shows that it goes to 100% performance under almost any load in order to keep it at a steady 80 degrees celcius.
I concluded that the fan was becomming less efficient over time and that it had to spin more and more in order to keep the temperature down.
Dust Cleaning
I try to clean the computer for dust every 4 month, blowing air backwards into the components of the computer to remove all the dust.
I normally use my mouth (trying not to spit) and a hairdryer. This seem to work okay for the most part, but not much for the EVGA 8800 GT.
After cleaning the fan is still quite audible and hovers at 85-90% under loading producing the annoying high pitch noise.
After only a few weeks its back at 100% under load. I tryed getting Apple to replace the video card, but they refuse to since it is still working. ( I hate this kind of deffinitions. )
- Would buying a can of compressed air and blowing it backwards into the EVGA 8800 GT remove more dust than the method I normally use?
- Would anyone recommend taking of the fan in order to clean it better or should the can clean enough? - trying to compare the risk of not being able to assemble the card again.
- Has anyone had any luck reducing the high pitch noise of the EVGA 8800 GT fan, and if so how?
Aftermarket Cooling
I did buy an aftermarket cooling system called Accelero S2 without the turbo module (fan) which recieves top reviews.
Despite having build some computers in the past I am a bit reluctant to install it by removing the fan completely because I am affraid that I will somehow break the video card in the process or accidently install it in a way that fries it when temperature rises under heavy load.
It sure is tempting to try the Accelero S2, but with the EVGA 8800 GT Mac going out of market I would have to dig deep in my pockets to get a replacement if something happends to the video card.
I think I also read somewhere that the instant you take of the EVGA 8800 GT fan you cannot put it back again. Which also makes me a bit nervous if the aftermarket cooler is not able to keep the card cool.
- Has anyone had luck installing the Accelero S2 without the turbo module (fan) and if so is it easy?
- Would anyone recommend installing the Accelero S2 without the turbo module? - I am not familiar with the success rate of aftermarket cooling and how skilled you need to be to be successfull.
- Has anyone had any problems not being able to keep the video card cool with the Accelero S2 and in that case was force to reinstall the default fan again?
I really wish I could reduce the noise of the fan so I can stand using it for 3d heavy stuff again.

My fans are constantly going on my g4 powerbook and the noise drives me nuts. I do all sorts of work - graphics (CS2), music recording, multimedia... but even when I am just not doing anything intensive the fans are on.
The fans are at full speed now and the temp reads 37C / 98F. I've used an icurve since I got the machine.I've put up with this noisy sound for a couple years now. One person said I need to clean the air vents, like dust is causing the noise. Does anyone know about this?
its a g4 titanium powerbook 867 mhz 768 RAM (ancient I know but it still works!)

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?

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?

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.

I have logitech speakers set up with my MacPro, and there is a steady stream of static noise coming from the computer. It's not the speakers because I have tested them with another device. It's definitely coming from my desktop. The strange thing is that if I restart my machine it goes away for a bit. But it starts back up as I open programs, browse the web, etc.

A couple days ago I upgraded my mid 2010 MBP 13 stock hdd(Hitachi 5400rpm 250gb) to a new one (Hitachi 7200rpm 500gb 7k500). I am still amazed by how much faster and more responsive system has gone.
Some change in noise/vibration was expected, but now I am starting to get a bit annoyed by vibration and HDD noise.
Vibration gets on my nerves- the levels are nowhere high, but there was no vibration in my stock HDD. In addition, the noise of the system on idle has roughly doubled- both fan and HDD are humming at the same level.
The system is still very quiet, but I could not help noticing it anyway. Is this normal?
I tried replacing the old HDD and found out that the problems were not present with it (=I am not likely to have made some awful mistakes putting the hard drive in).
Then I tried tightening all the screws as hard as possible and putting some rubberized washers on the corners of the HDD to ensure snuggly fit. All efforts rendered no change. Are there any other methods to reduce noise and vibration?
Furthermore, I still have one day to return the 7k500 without any loss. Should I get WD Scorpio Blue 500gb instead?
I have read user reports of similar problems with WD SB 640gb drives as well. Since these drives are essentially the same, I would expect similar problems with 500gb as well.
P.S. Is there any chance that the stock HDD is slightly "downclocked" by Apple? It does vibrate a lot inside external cradle. Furthermore, I tested a couple laptops in the local Apple store. Both MBP 15" and MBP 17" where equipped with 500gb 5400rpm drives.
However, MBP 17" was vibrating much more than the MBP 15" (maybe MBP 17 HDD runs at its native speed to increase the performance. The increased size of 17" makes the vibration effects less annoying).
The stock HDD vibrates just like the current one until after 1-2s after the power button is pressed- as if some sort of regulation kicks in after that point.

This has been driving me nuts for a few months now. My macbook keeps emitting a sound very much like static. Only today, I realized that this sound goes away when the processor is working. So if I scroll down in Safari, open a New Folder, etc, the sound briefly pauses before resuming again. Almost sounds like a refrigerator. It bugs me a lot lot. Anybody else having this issue? Or has Apple been able to fix this for anyone?

I connected my MacBook Pro to my TV (non-HD) using a 3.5 to L/R composite for audio (from headset hole) and an Apple DVI to S-Video/composite for video. I'm using the S-video part of the adapter. I get good sound out of both channels, but when I connect the S-video cable, I immediately get static feedback from the stereo speakers (the L/R composites are connected directly into my stereo receiver and the S-video goes into my TV).
The video quality is fine when it's connected...

There is a loud and really annoying humming & static noise when I connect my charger to my MBP. The humming only comes out of the headphones jack, and not the MBP speakers. This really cripples me in my work as I am a music producer.

My brand new MBP 13" (Mid 2009) makes a high pitched whiny sound that appears to come from the upper left corner ( where the MagSafe connector is). It is not caused by the display because even when I turn it off (the display) the sound is still there. It goes away when I turn off the computer, tougth. Also it's not caused by the MagSafe because when I disconnect it the noise doesn't stop. I have used gogle and the forum search and found people with the same problem. Those people could fix it by starting photobooth. Same works for me. So I guess it's the processor. What I want to know is: is this normal? Because most of the other people who I found who have this problem had a 2006 MBP not a 2009 like me.

Very occasionally the screen on my iMac (early 08 24") goes blank and it makes an incredibly loud static sound that's independent of the volume control setting. The power then needs disconnecting to restart the machine. Haven't been able to tie it to any specific program. Apple Care asked I leave it on logged in on a new user account (at the time I originally thought it only happened in sleep mode, but have since discovered this is not the case).
It's happened maybe 3 or 4 times in the same number of months. I've only found one similar case on the net, with someone suggesting it was Safari 4 beta, which I've found not to be the case with mine. It's on extended warranty. I think there's something seriously wrong with it (it's already had the hard drive and power supply replaced).

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?

I have just noticed a weird clicking noise coming from the left hand side of my macbook. It only clicks when the macbook is being moved about or a sudden movement occurs. I thought it might be the HDD motion sensor but since its coming from the left hand side it's concerning me slightly.

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.

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.
Issues:
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...

I have a 7 day old Macbook Pro 13" 2.26GHz and sometimes when I open the screen I hear a click noise coming from the right side of the hinge it happens about half way open and some times when I pick it with the screen open it doesn't happen all the time it was doing it about 30 mins.
ago but as I type this its not doing it. Should I take it to the Apple store tomorrow or should I keep an eye on it and see what happens?
