Another weird noise from my 2011 15" MBP (6750M)

Whenever I scroll down a webpage in Firefox with some graphics on the page, or another OSX window on top of Firefox, I can hear the gfxcard (left to the trackpad) making a noise that is clearly in sync with the scrolling I do. I can hear it when in a quiet room well enough to be aware of it.
Anyone experiencing this?
You can test for it by scrolling a webpage in Firefox while there’s another window on top (see here: http://www.youtube.com/watch?v=STico7bHXl0 ). It only happens with certain applications, e.g. scrolling in Safari doesn’t produce this sound. English isn’t my native tongue so my characterization of it will be lacking, but I’d would describe it as dense crackling in rapid succession.

You're fine. You're probably hearing the voltage regulators twitching because you're putting a load on the GPU.
FFX4 uses your GPU if hardware acceleration is turned on. (Preferences > Advanced)
Safari doesn't (yet).

Weird Noises from Macbook Pro

Some Weird noises from my MacBook Pro mid to late 2014

Maybe you could describe what kind of "weird" noises you are hearing? Everybody's perception of weird is not the same, and something that you may think is weird may have a logical explanation. But we can't even begin to diagnose it without a little more to go on....

Weird noises from HP Pavilion m7

I hear these weird noises coming from my speakers on start up and shutdown or even going on youtube. I Reinstalled IDT high definition driver couple times cause Hp Support Assistant upgraded my IDT drivers and my BeatsAudio doesnt work. When i reinstalled it, it works but when i restart my laptop it makes this weird almost-like static like noise.Is there anyway to fix this?
This question was solved.

Hi,
Try the following.
Download the IDT Audio installer on the link below and save it to your Downloads folder.
ftp://ftp.hp.com/pub/softpaq/sp57501-58000/sp57966.exe
When done, open windows Control Panel, open Device Manager and open up Sound, Video and Game Controllers. Right click the IDT device and select Uninstall - you should also get a prompt to remove the current driver, tick the box to allow this and then proceed with the uninstall.
When complete, shut down the notebook, unplug the AC Adapter and then remove the battery. Hold down the Power button for 30 seconds. Re-insert the battery, plug in the AC Adapter.
Tap away at the esc key as soon as you press the power button to enter the Start-up Menu. Select the Bios Menu ( usually f10 ). Press f5 to load the defaults ( this is sometimes f9, but the menu at the bottom will show the correct key ), use the arrow keys to select 'Yes' and hit enter. Press f10 to save the setting and again use the arrow keys to select 'Yes' and hit enter.
Let Windows fully load, then open your Downloads folder, right click on the IDT installer and select 'Run as Administrator' to start the installation. When this has completed, right click the speaker icon in the Taskbar and select Playback Devices. Left click 'Speakers and Headphones' once to highlight it and then click the Set Default button.
Restart the notebook.

Clicking noise from back left of MBP -- speaker maybe?

Hi all,
I have a clicking noise coming from the back left of my MBP and I'm wondering if anyone else has this problem, has any suggestions, or knows if it is potentially bad.
I saw the long thread about a 'pop' noise here:
http://discussions.apple.com/thread.jspa?threadID=1234166&tstart=0
... but I'm not 100% sure mine is related.
I looked at some MBP take apart guides and see that the hard drive is in the front left, but my click seems to be coming from the back left (if I put my ear on the front left I can hear the hard drive spinning and all, but the click doesn't seem to come from it). I tried the hdapm suggestion in that thread just for kicks, but nothing happened, so overall I don't think it's the hard drive.
The only moving part in the back left as far as I can tell is the left fan, but I checked the fan speed with smcFanControl, and they were both at 2k (normal speeds). Plus, it doesn't sound like something I would expect a fan to make, but I could be wrong. The click happens in bursts usually, clicking about once every 5 seconds (it seems pretty consistent) for a while, but then has long periods without clicking. It doesn't seem to click more or less depending on computer usage. I would think that if it were a fan noise, it would click a lot more often (every 1/2000 seconds! ;>), and I don't see why it would come in and out in?
I'm wondering if it might be a periodic pop from the speaker. It happens when the volume is down & muted, though, so that seems somewhat odd. If it is the speaker, I don't think it has anything to do with interference, as it will make the noise when the computer is on battery power, with nothing plugged in, far from any electronics.
Overall, I'm pretty confused, so any advice would be great. At the moment, taking it into an Apple Store won't really work for me :/ I used to have a PowerBook & a G5, but I sold both of them when I bought my MBP, and this is my only computer. I have a NAS that I've backed up all my data to -- so I'm not really concerned about losing stuff if something dies -- but I need my MBP for work, so I can't live without it for a week or so if they need to hold onto it. Does anyone have any ideas about what might be happening?
Thanks!

Welcome to Apple Discussions!
I didn't read all of that long thread, but I have heard of the type of noise you describe being associated with the hard drive. Whether it's benign or ominous or something else entirely is hard to say. But there are a couple of little utilities that can help you evaluate your hard drive:
S.M.A.R.T. Reporter:
http://www.corecode.at/smartreporter/
S.M.A.R.T. Utility:
http://www.versiontracker.com/dyn/moreinfo/macosx/32454
The former will monitor the S.M.A.R.T. status of your hard drive and install a beautiful icon in your menu bar. The icon will be green if the S.M.A.R.T. status is verified and red if it is failing. It is designed to give you a heads up if it detects hard drive problems.
S.M.A.R.T. Utility is not supported on all hard drives, but if it is, it will allow you to see various factors which determine the S.M.A.R.T. status and if there are problems with any of them. This can also give you early warning of hard drive failure.
Also, there have been some problems with one model of Seagate drive, so check and see if you have a Seagate.
My Fujitsu drive is absolutely silent, and that is what you should expect. My external La Cie makes clicking noises every so often, and always has, so I think that is normal for it.
The main thing to worry about is the hard drive.
Do you have the widget iStatPro? It might be better for monitoring the fan speed without using smc fan control. But if the left fan is at 2000 RPM, then I would expect a very rapid click, which does not sound like it's the case here.
One last thing--does the click vary with the volume? Does it get louder if the volume is turned up high and quieter if the volume is turned down low? If the click has to do with the speaker, then I might expect the click to be louder or quieter depending on how the speaker volume is set.
It may be worth taking it to the Apple Store just to let someone listen to it and give an opinion. If you are under warranty, at least get a case number to document the problem. I understand that you can't be without your Mac for a week or so, but if a problem is diagnosed that does need to be fixed, then you can work on getting the work scheduled for a time that is convenient to you. It may even be possible to arrange for a loaner with all your stuff cloned onto it. Knowledge is power, and will give you better options than, say, having a sudden hard drive crash.
Good luck!

Weird noise superdrive late 2011 Macbook Pro

Weird noise from CPU

A few nights ago I awoke to hear my P-book G4 making a loud crackling noise so I freaked out and shut it down. After restart the next day it booted fine and then just booted up to a blue screen. I Waited until today and I tried to reboot off of the startup disk, and it spit that out and then all of a sudden it restarted normally but made those crackling noises again. THe noises have now stopped and I am running disk utility on it to see if that helps but does anyone know anything about this issue and if so could I have some help. Thanks

Denny: Replace your hard drive. The optical drive can't possibly make crackling or grinding noises without a disc in it, and it can't slow the operation of the computer to a crawl or prevent a normal startup from the hard drive. A failing hard drive would account for all the symptoms you've experienced, including the awful noises. Replacing the HD is easy; instructions for doing so are right in your Powerbook owner's manual.
I hope all your data is backed up, because any grinding noises you've been hearing could have been the read-write heads in your hard drive plowing furrows into the surface of the platter where your data used to be. You'll be very, very lucky if you're able to recover everything important from that drive. The more you try to use it, the smaller your chances of salvaging anything from it will become.

IBook will not power on suddenly, weird noise from CD drive

Hello!
My iBook G4 (800 MHz, 512MB RAM) was working fine yesterday, then suddenly this morning it wouldn't power on. When I press the power button, I can hear the hard drive start spinning, but there is no chime and no screen. It just stays black.
The optical drive also makes a strange noise. Usually when you start it up, you can hear the CD drive make noise like it does when it ejects a CD. But now, it sounds very strange. If I had to guess, I would say that it sounds like it is going out.
I have tried to start without the battery and have reset the PRAM and PMU multiple times without any luck. Any thoughts would be appreciated.

gjortega ,
Here's the troublshooting guide from the service manual:
"Startup
The computer will not power on
1. Remove any connected peripherals.
2. Try known-good power outlet.
3. Try known-good power adapter and power cord.
4. Remove battery.
5. Reset the power manager by pressing the key combination Control-Option-Shiftpower.
Warning: Make sure you do not hold down the "fn" key when resetting the
power manager.
Warning: Resetting the power manager will permanently remove a RAM disk, if
present, and all of its contents. You will also need to reset the date and time
(using the Date & Time control panel).
6. Disconnect internal keyboard completely. Inspect connectors. Restart with keyboard
disconnected.
7. Remove any additional RAM and AirPort Extreme Card.
8. Try known-good DC board.
9. Verify power button is connected properly to logic board, if power button is not
functioning correctly or damaged, replace the top case.
10. Replace logic board."
Now that #10 would be about U28 or the GPU. U28 is that site I sent you. The GPU sits under the option-Apple key and you can put pressure on it from underneath that area. There is a large heat spreader that sits on top so you have to come from underneath.

Macbook Pro making loud and weird noise

Okay, so I was just watching some videos on youtube and I fell asleep. Even the battery drained to zero% and hibernated. Then after around 7 hours when I woke up, and turned it on again then it started to make really weird noise from inside like hmmm I couldnt figure what was the problem, either the speakers? Fan? Hard-disk? Superdrive?
Then I turned it off and turned on again. It was quiet for a moment until the log in window appeared and started to making same noise again. Then I cleared PVRAM or something holding down Command+Option+P+R and Power Button then it is kinda fine now but still loud enough to bother people.
It seems like some wire or hmm something is stuck inside some moving part inside it but I am not sure. I just keep my Macbook Pro on the table all the time as a desktop I have never had such problem before.
Help please? What do I need to do? It's a

You said at the start that the battery discharged completely...did you plug the MBP in and recharge? Does the MagSafe show it is charging or running on AC?
Does the noise sound lik a clicking, sound the hard drive stepping motor makes? Or is it more of a hum, or a grating sound? If the latter it could be a fault with a fan or a bad bearing in the hard drive.
How does it perform otherwise?
Might be a good candidate for a visit to the Apple genius bar and have the techs run some diagnostics.

Very weird noise...

I was using photoshop on Windows with my MacBook Pro and all of a sudden I hear this noise that sounds like it's loading something. Most of you know that with a MacBook Pro that when loading takes place you can hear it in the centre / left side. Usually the only noise that is coming from the right is when you insert a CD. I have no CD's in my drive and I never heard this sound before. It just randomly started happening, never moved / bumped my MacBook, was just using photoshop.
The noise would get louder then it would slow down stop for 5 seconds, then go back up... and it's freaking annoying.
Should I System Restore or something? I have no idea what to do.

For some reason it's not letting me edit so I keep having to reply. Anyways, when it's not making the weird noise from the right side, it now makes this deep quiet noise in the centre, it sounds like an idle engine, literally. What is happening to my laptop all of a sudden!?

Satellite C665 - Noise from Adaptor

Hi there,
I bought this Toshiba Satellite C665 from JB HiFi Australia about 2-3 weeks ago. Today I suddenly heard some weird noise from the adaptor. I really don't know how to describe the sound, but I did recorded using my mobile.
The weird noise lasted for about 30mins. Now it stopped but I am a bit worried - whether it is safe to use this adaptor or not.
Is this just normal for Toshiba adaptors?
Should I take it to Toshiba and get someone to check it? Will you guys charge me service fee for this?
And I don't know who I should contact in ANZ.
PS. I can upload there recording if needed, the mp4 file is just about 132K.
Thanks,
Soph

Hello Soph
Unfortunately I cannot give you some precious answer but I never heard noises on my adaptors.
I recommend you to contact nearest Toshiba service provider and ask for help.
In worst case they can order new AC adaptor and replace it.

My Powermac g5 makes wierd noises from PSU

My Powermac g5 makes weird noises from PSU is not continuous it does that irregularly could be the PSU Frying or is just the fans going bad ?

I'd say it's most likely the fan going bad, but have you blown the dust out of the PSU lately?

I recently downloaded the latest OS update and now I have a constant "humming" noise from my MBP and my audio output is no longer working. Any suggestions?

I recently downloaded the lastest OS update (Lion X 10.7.4) on my MBP that I purchased in November of 2011, and since downloading it my MBP has been making a constant "humming" noise from the right speaker/disc drive area. I also don't have any audio output for FaceTime or Skype. I attempted to use Photo Booth to record a video and it doesn't record any audio. I attempted to reset SMC and reinstall Lion with no resolution of the problems.

Click the Finder icon on the Dock.
Applications > Utilities > Audio MIDI Setup

Move the Master volume slider to the right a bit.
Best.

Late 2011 15" MBP periodic burst of white noise

Has anyone found a solution for this problem? Every 30 seconds or so, I hear a burst of white noise. I'm running a late 2011 15" MBP. My co-worker has the same problem running a 2011 13" MBP. It doesn't seem to be due to any 3rd party software as we're both running different problems. It also happens with nothing running.
Thanks.

Please read this whole message before doing anything.
This procedure is a test, not a solution. Don’t be disappointed when you find that nothing has changed after you complete it.
Step 1
The purpose of this step is to determine whether the problem is localized to your user account.
Enable guest logins and log in as Guest. For instructions, launch the System Preferences application, select Help from the menu bar, and enter “Set up a guest account” (without the quotes) in the search box.
While logged in as Guest, you won’t have access to any of your personal files or settings. Applications will behave as if you were running them for the first time. Don’t be alarmed by this; it’s normal. If you need any passwords or other personal data in order to complete the test, memorize, print, or write them down before you begin.
Test while logged in as Guest. Same problem(s)?
After testing, log out of the guest account and, in your own account, disable it if you wish. Any files you created in the guest account will be deleted automatically when you log out of it.
Note: If you’ve activated “Find My Mac” or FileVault in Mac OS X 10.7 or later, then you can’t enable the Guest account. Create a new account in which to test, and delete it, including its home folder, after testing.
Step 2
The purpose of this step is to determine whether the problem is caused by third-party system modifications that load automatically at startup or login.
Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards. Boot in safe mode and log in to the account with the problem. The instructions provided by Apple are as follows:
Be sure your Mac is shut down.
Press the power button.
Immediately after you hear the startup tone, hold the Shift key. The Shift key should be held as soon as possible after the startup tone, but not before the tone.
Release the Shift key when you see the gray Apple icon and the progress indicator (looks like a spinning gear).
Safe mode is much slower to boot and run than normal, and some things won’t work at all, including wireless networking on certain Macs.
The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
Test while in safe mode. Same problem(s)?
After testing, reboot as usual (i.e., not in safe mode) and verify that you still have the problem. Post the results of steps 1 and 2.

Everytime my phone vibrates it makes this loud noise from inside that sounds like a weird cracking noise or something help!!

Okay so I noticed a week or two ago that there was something lose on the inside of my iPhone 5s and ever since then when my phone vibrates sometimes there is this weird noise. It sounds almost like a cracking noise from the inside or a weird electrical noise. I think something is wrong with the vibrating part. Does anyone know if this is fixable or what it is?

Hello ashliz17,
After reviewing your post, it sounds like the phone makes a cracking noise when it vibrates. I would recommend that you read these articles, they may be helpful in troubleshooting your issue.
