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?
View 2 RepliesI 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?
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'll be using the Air and all of a sudden there will be static or electrical buzzing coming out of the right speaker on my 13" MacBook Air. It's about 16 months old.

My family just recently upgraded from an old PC to this 27" iMac, during the early part of the summer. While using it over the last little while, I would notice a noise that sounded like a harddrive spinning or possibly some sort of a fan noise. The best way to describe it would probably be as digital noise. It's not incredibly loud, but it's a decent volume, and can get quite annoying. It has a little bit of a squeak to it.
Over the last little while, it's become more constant. When the computer is in use, it'll usually occur quite often. It's quite annoying and obtrusive when I'm watching videos and I'd like to know what it could be.I think our computer is still under warranty, so I'm hoping to find out if it is something wrong, so I can get it replaced.
I've also been wondering if it's a fan, or a regular noise. However, it's so constant that I'm starting to wonder. The other night, I was watching a video and it seemed like it was coming on every 30 seconds for a long span of time. We don't run any memory heavy programs on this computer. If anything, we're just using Firefox, iTunes and/or Messenger. Sometimes Office. There's little to nothing stored on this computer, as it's brand new, so most of its memory is free.
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?
View 3 Replies View RelatedHas 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 am just wondering why, when I close the lid, it makes a ticking noise. It is as if something is stuck in the hinges but I've checked and cleaned it and it seems fine. Anyone else had this problem or know how I should fix it? It used to be smooth and ticking-noise-free, but now its gone funny.
View 2 Replies View RelatedSo I turned on my Macbook Pro today and this clicking noise is coming from the rightmost fan hole. I am really nervous that it is a serious issue as I use my Macbook for probably 15 hours a day for all sorts of artistic ventures.
After exploring, I've discovered with I use it on certain angles, the clicking stops, or increases/decreases in noisiness
Anybody have experience with this? Is there a way to clean it of the issue?
I haven't had any problems with my system before, and the computer itself is operating perfectly
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.
View 10 Replies View RelatedJust 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.
View 24 Replies View RelatedI 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?
my macbook pro makes a slight ticking noise when i move it or tap it just a little bit it seems like its coming from the right palm rest any thoughts, i think it maybe the hard drive or something. oh yeah 2010 mbp 2.4 ghz 320 hard drive
View 1 Replies View RelatedFirst of all, my Macbook doesn't make ANY noise. Is very silent, but everytime I start a game, or I start to upload some files, the fans start to flip faster and faster and makes a big noise, like a rocket being launched. When I stop the game, the fans start to go slowly.

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?

I dont know how long this has been going on for but ive just noticed it. ONLY when the display sleeps, the upper left hand side of my 24" imac makes light ticking noises once every few seconds (its very light ticks, theyre hard to hear unless you put your ear to the computer). It doesnt occur when the screen is on and when everything is on, and it doesnt occur when the computer sleeps, it only happens when I put the display to sleep, which seems weird. I don't think its the HDD, I've checked the SMART status and all is fine, I've also checked the console. Why is this ticking noise occurring when the display sleeps and no time else and what is making it?
View 2 Replies View RelatedAfter purchasing the alu. macbook, I find my self buying all the necessities: again. quit frankly its getting old. It does seem like most apple computers are what some might call overpriced to begin with, but I am ok with that; you get what you pay for and i don't mind paying the mac tax. But as I purchase the odds and ends required to use my computer in the real world, it seems as if apple is taking advantage of the fact that our computers lack some of the hardware to connect with to overhead projectors, etc. (as most PCs can). I mean $29.99 for a 3 in. piece of plastic and wire???
I was just wondering if anybody has found an alliterative source for adapters?
Today, my mac freaked out on me twice. I was watching something via Quicktime and all of the sudden the screen went black and green and started going crazy like it was twitching or something. And I got this loud noise coming out of my speakers. My MacBook is about 3-4 years old.

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?
I have had my new pro since christmas, and it has been incredible. however i noticed from day one that periodically i get this buzzing noise coming from the left speaker - closest to the screen. is it the hard drive? what is it... and is it normal? sometimes if i tap the speaker area (next to the magsafe) it goes away.. and other times its pretty loud. i do NOT have applecare. should I purchase that as well.

View 24 Replies View RelatedOn my 13" MacBook Pro, the hinge makes a cracking noise on the right side of the computer (near the power button) when the screen is positioned all the way back.
The entire hinge also makes a loud popping noise when I adjust the screen position. The screen seems very tight, and it takes a little bit of effort to move the screen, and when the screen is moved it makes the loud popping noise.
This is probably going to make some of you guys cringe, but sometimes putting pressure down on the top of the case close to where the black hinge meets to unibody enclosure seems to stop the popping noises. Putting downwards pressure on the hinge, or flipping the computer over and putting pressure on it that way, also seems to alter how much popping noise there is.
If I mess around a bit with applying pressure on different parts of the computer around the hinge, I can usually eliminate the noise. But, the cracking noise when I put the screen all the way back is still there.
It's not interfering with the operation of the computer, it's just incredibly annoying and this is only a four month old machine which shouldn't be creaking and cracking already.
when I was browsing the BBC website . I happened upon the front page and could hear a crackling sound, eventually after looking round the room for about 5 minutes I realized it was the macbook.
When the news page 'scroller' at the top types its news story out in a tika tape kinda way that is when the crackling noise happens .
does this make sense ? is my macbook faulty ? ..does it take soo much power to perform this function as to make my macbookCPU crackle ?
the noise is coming from approx the center of the notebook and is quiet(ish) but audible enough
anyone have any ideas ?
link to the site is below , you'll see the words scrolling across the screen at the top which then creates a clickable link to a news story : URL
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?

What do you think is going on?
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?
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]
