Strange Noise When Powering Off

This just started this morning. It makes a really odd noise when turning off. Any ideas? I have no idea what I have done if anything at all.

Just started. Did you do any updates yesterday? Just start with a reset, hold the top sleep/wake button down and then Home button down at the same time until you see then white apple logo.

My MacBook Pro makes strange noises when I open iPhoto and when I close it.

My MacBook Pro makes strange noises when I close my laptop and when I open iPhoto. iPhoto then proceeds to close when the noise stops. Is there any cure for this? Please help.

What kind of noise? Any other app make noise?

Keypad & trackball remain illuminated when powered-off

I've had the pearl for 18 months with no problems. Suddenly the keypad & trackball will remain illuminated all the time, even when powered-off. This rapidly drains the battery. I've performed a hard and multiple soft resets and removed and cleaned the trackball-- no luck. Everything works fine. I appreciate any suggestions?

My mac mini only shows a steady power light and fan noise when powered up. No video or sound and no commumication with wired keyboard or optical mouse. Tried replacing internal battery and resetting PMU/SMC but nothing seemed to happen. Any suggestions?

You've already done the two things I would have suggested.
If your Mini has an internal battery then I assume it's a G4. That means you've gotten a lot of good years of service from it, and it's old enough that it's certainly not covered by AppleCare anymore, and it's probably not worth spending money trying to repair it.
You should be able to tear it apart using instructions from ifixit.com to get the hard drive out, and then put the hard drive into a nice USB or FireWire enclosure (I like the ones from Other World Computing, macsales.com) so you can transfer your data to a replacement Mac.
I hope someone has another suggestion for you.

When powering off my iPod touch, any application (facebook, viber etc)installed using App Store won't work again

When powering off my iPod touch, any application (facebook, viber etc)installed using App Store won't work again
How to solve this issue?

Try a hard reset first. Press and hold both the Sleep/Wake and Home buttons together long enough for the Apple logo to appear.
If still no luck, try downloading and installing a new app from the App Store. Doing so has cleared the issue up for several users.

Saving Place When Powering Off Ipod Touch

When I turn off my ipod touch completely it always loses the song I was last on. This does not matter if I am playing a specific album or shuffling all songs. My other ipods (nano, mini, shuffle) always keep the place even when powered off. Is there a way to get the touch (2G) to save its spot?
I note it does save it if I only put it to sleep and not power off completely. if I am not using it for a couple of days, should I put putting it to sleep or powering it off?

The iPod is telling you to connect the iPod to your computer with iTunes. When connected, iTunes should open and tell you what to do. If it does not, you want to do is to restore the iPod from backup.

Make big noise (alarm) when powering off

the first thing a thief would do after stealing your phone is to power it off.
Although there is a cute app that offers a little more protection (called theftalarm), this only works when plugged.
Does anyone knows an app that would hook into Springboard/Mobilesubstrate and make an as loud as possible noise when you hold the power button and require security code before allowing a powerdown?

There won't be any apps for a non-jailbroken iPhone to do this, as none would have access to the private API's necessary to do so.

My ipod touch makes a strange noise when makes the synchronization with itunes

At first my ipod touch began doing strange noise in differents situations. Yesterday I try to solved it doing this: I connected it to itunes a made a restore. I thought it was solved, but today the noise came back. I could identify when it happens. If the ipod is off and I plug the usb cable, itunes starts and the ipod turn on, then the first thing it do is connected to the wifi network, then syncronizations began and the strange noise is heard.
Some idea?
Do you think it would be neccesary to visit an apple store to solve it. My ipod is even covered by warranty.
Thank you very much.

Hey DerikK,

Think Station S20 speaker noise by powering off

Hi,
my Thinkstation S20 (4157) always makes a noise (internal and/or external speakers) when I power it off,
it sounds a little bit like if you power off a guitar amp while the guitar is still plugged in.
I´m sorry for the bad descreption.
The noise is only by powering off, not during restart, on win and linux.
Bios version is 1.39.
Do you have the same on your systems or is it somehow a failure on my S20?
Thanks for your answers!
Edit: Could this be a solution? http://en.wikipedia.org/wiki/Line_filter
Solved!
Go to Solution.

that one is new to me. it could be tied somehow to power management in Ubuntu but i honestly don't know.
admittedly, i haven't used Linux for over a decade, back when you had to hack your own XF86Config files using hsync/vsync data direct from chipset manufacurer datasheets. these days everything is point-and-click. lol
anyway, you could try playing with various processor power management settings in the BIOS to see if that helps.

Quiet, high pitched squeaking sound when powering off 60D?

I just got a 60D body yesterday, and I just noticed a high pitched, very quiet noise that happens for a second or two when powering the 60D off. My Rebel t3 does not make this noise so I was wondering if it's normal?

That's the noise of the piezoelectric cleaning system. It vibrates the low pass filter (located just in front of the sensor) to shake dust loose.
In some cameras it sounds like a couple of squeaks. My 60Da makes the same noise. No reason for concern. Some cameras start out not squeaking when new and end up making the squeak later.
The good news is I have never heard of it actually being a problem.
No, the good news is that the OP is still young enough to be able to hear a squealing sound at such a high frequency!

Messages from iPad not Synching with MacBook Pro when Powered Off

I have the new MacBook Pro (2 GHz, i7, purchased Feb 2014), 15" Retina running OSX 10.9.4. I also had an iPad3 (Retina) but just upgraded to the new iPad Air 2 weeks ago. I do not have an iPhone, but that's next. I have used the same iCloud account for all devices.
The issue:
Messages (or message conversations) that I have when using my iPad Air are not synching with the MacBook under certain conditions.
1) If my MacBook is on, there is no issue. Messages between devices (whether being composed on the iPad or MacBook) synch instantly between devices.
2) If my MacBook is sleeping, most (but I do not think all) messages sent from my iPad will synch with the MacBook when it wakes up from sleep.
3) If my MacBook was powered off and I had message conversations using my iPad while the MacBook was off, these messages do not synch with my MacBook after I turn it back on. BUT, this depends:
     a) if I power on the MacBook shortly after (5-10 min) I had the message conversation on the iPad, sometimes these messages on the iPad will synch with my MacBook after I power it on.
     b) If my MacBook was powered off for several hours after I had a message conversation on my iPad, and then I power on the MacBook, these conversations are not synching on the MacBook at all.
     i.e Assume MacBook is powered off. I have a message conversation on my iPad at 4:30 PM. If I power on my MacBook at 4:35 PM, the message from my iPad synchs with the MacBook. However, if I power on my MacBook say at 10 PM or the next day, then the message conversation I had on the iPad DOES NOT synch with my MacBook.
Confused? So am I. To complicate matters, I did not have these issues while I had my old iPad 3. I only starting noticing it when I bought the new iPad Air two weeks ago. I do not know if this is related.
Another issue: SOME message conversations on my MacBook and iPad air now appear to get out of chronological order. In fact, on my iPad air, I received a message at 10 AM (message A) and then had several other messages with this person throughout the day on my iPad (at 11 AM, and then 2 PM). Later that evening around 10 PM, the original message (message A) was received again as a new message on my iPad (i.e. received a new message notification). Now, message A appears out of order (it shows the timestamp of 10 AM, but it displays after the messages that came at 11 AM and 2 PM). Since my MacBook was on, these messages synched with my MacBook, but were (and remain) in the proper chronological order.
Other iCloud apps (calendar, mail, FaceTime notifications, notes, keychain, Photo-stream etc. seem to be synching fine between devices). One last observation, when I bought the iPad air and restored it from the backup I made from the old iPad 3, everything restored fine from the backup except for Calendar. For whatever reason, some old calendar entries did not restore on the new iPad.
I have run a myriad of tests (sending messages to myself from both my new and old iPad (even created a new apple ID from the old iPad)) with my MacBook sleeping or powered off for varying amounts of time in order to provide the information above. I also reinstalled the operating system on my MacBook but this did not resolve the issue.
If anyone has any ideas or suggestions, I would be extremely grateful. I have been in contact by phone with Apple support and have them baffled as well, but they are doing their best to help.
Thanks,
HankSTL
ps. I may post to several communities so if you see this message in several communities, I am just trying to get the best coverage.

The same thing is happening to me.

Two iMac's 24 inch make soft rattling-kind-of noise when turned OFF !?

Apple-helpdesk Holland has no records of this "complain":
Me and my colleague have bought a new iMac 24 inch two months ago.
When our Mac's are turned OFF they keep making a very soft continuously rattling-kind-of noise, even after a couple of hours being turned OFF.
The sound is NOT annoying, we just want to know if its normal and our Mac's won't quit working in a few months because of a defect related to this noise.
At the Appledealer there's too much noise in the shop to notice this sound.
My Mac (CTO 2GB) was shipped in from the East and my colleague bought hers three weeks later directly in the Apple-store.
Needless to say; we live in different houses. Neither of us have connected devices to our Mac's.(only the internetkabel is connected)
When we pull the plug out of the socket, the sound dissapears.
I think that it would be too much of a coincidence that we both have the exact same defect in our Mac, so probably there are other iMac 24 inch owners with good hearing who can confirm this very soft continuously rattling-kind-of noise when de Mac is turned OFF.
You really have to put your ear close to the top-ventilationsplit on the backside to hear this sound.
Please let me know if you hear this very soft continuously rattling-kind-of noise aswell !
Thanks a lot!

Satellite C855 - strange noise when tried to watch/listen something

I bought this laptop around a month ago. When I first tried to watch or listen something, sizzling kinda noise came up for a few seconds and gone.
I didn't think that it was important. But now, it happens everyday and lots of times when I listen or watch something. It buzzes, sizzles for a few seconds and it is really annoying.
What could the problem be?
Please help me...

Are you sure the buzz and sizzle come from the speakers / headphones?
Maybe the strange noise comes from HDD?
In this case it would be an HDD malfunction.
It could be also possible that this strange noise appears because of stressed CPU.
In such case the applications (player) hangs / freezes for a second and creates some strange noises.
Would be interesting to know if system restore / system recovery would fix it

Network knows where your phone is when powered off?

An AT&T rep just told me that the network "knows" where your iphone is even when it is powered off. The particular issue is when traveling out of the country. Just powering off the phone will not ensure that you do not recieve charges. If someone leaves a voice mail or text message and you do not have an international plan then you will get charged even if the phone is powered off.
Really?

I meant perhaps she misunderstood. Not having been part of the original conversation, I am not qualified to judge exactly what happened. I am, therefore, inclined to try to give everyone the benefit of the doubt.
Of course if you have been in the "wireless business" for 20 years, you would already have known what I told you, right?
