Hot MagSafe plug / connector & " whine" whining noise

Hello -
MacBook user (MacBook2,1) on 10.6.7 with a reasonably new magsafe charger. For the last day, the computer makes a high-pitched hiss or whine / whining noise when plugged in. Also, the magnetic connector gets unusually hot. The battery is not hot, but the rear of the MacBook near the MagSafe port is hot.
I am getting tired of calling Apple about a variety of post-10.6.7 issues and thought I'd ask here first for ideas. Likely I'll take this to the Genius Bar...
Gregg

Ah. Foolish of me to expect Apple to actually monitor their own discussion forums, I suppose.
Basically the question(s) come(s) down to, "why is there a horrible whining noise playing through my car stereo when the usb plug of the official apple a/v cable is plugged into a charger when there is no noise whatsoever when it isn't plugged into a charger...?" Furthermore, "why does the official iphone a/v cable cause the iphone to inform me that it's not a recognized peripheral (or words to that effect" and lastly, "why does the iphone suggest switching to airplane mode when I use it to play music in car as I believed the iphone to be perfectly capable of playing music whilst still acting as a phone." The last point is why I bought an iphone istead of, say, an iPod AND a separate phone...
Pretty much as I said in the first post, really.

Applecare expires, and here comes a strange whining noise!

There's an annoying whine coming from the left fan area on my MBP near the adapter port, and the left fan seems to be running more than usual. The whine tone seems to change depending on what I'm doing. For example, when I scroll up or down in my browser it goes away but returns when I stop. If I use the dock, the pitch changes.
My MBP was the first generation to feature the Core 2 Duo, so it's a few years old now. I upgraded to Snow Leopard a few days ago. No major problems other than that both my fans running more than normal for a day or so. I've heard that this was common for those that upgraded to SL on an older MBP. Did my get overworked?
This whining noise is very annoying, and of course my Applecare just expired a week ago....
Any ideas out there?

"No major problems other than that both my fans running more than normal for a day or so. I've heard that this was common for those that upgraded to SL on an older MBP."
I've had no fan issues since updating to to SL. Where did you hear about this "common" problem?
See if resetting the SMC helps.

"I upgraded to Snow Leopard a few days ago."
According to the cardboard insert inside the SL disc cover, you have 90 days of FREE phone tech support from Apple. Suggest that you give them a call.
If your problem turns out to be hardware related I would give Customer Relations 1-800-767-2775 (US only) a call. See what they can do for you if AC expired just a week ago.

"Processor" Preference Pane and whining noise

I used to have a TiBook, which worked fine. Then I bought a MacBook Pro as soon as it was announced, and I was stuck with one of those models that had the high-pitched, whining noise:
(http://www.red-sweater.com/blog/macbook-pro-noise-complaints)
It seems that this noise was coming from the Intel processor in the "naps" it would take. After a year of complaining, Apple finally accepted my computer for repairs and soved that issue.
In the meantime, my mum would use my old Titanium PowerBook and at some point (after some MacOS upgrade???) that one would start doing precisely the same whining noise, too.
The funny thing is that I also noticed the Control Panel exhibiting an additional pane, called "Processor", whereby you could inhibit the hissing and whining noise by unchecking the "allow nap" button. Strangely, I don't have that control panel on my MBP (why?), even though we both have 10.4.11. If I uncheck "allow processor naps", the whine stops, but the computer vent goes off often, which is equally annoying.
So does anyone know the story of why at some point the PowerBook G4 would start having that whining hissing noise? (About the same time when my MBP was cured of it?) And most of all: does anyone know how to return the TiBook to its original state?
(I posted something on the TiBook forum recently, yet the discussion was helpful but inconclusive there:
http://discussions.apple.com/thread.jspa?messageID=6199028#6199028 )

Hi,
I can't comment for most of your questions (as I don't know ) but:
Strangely, I don't have that control panel on my MBP (why?), even though we both have 10.4.11.
The processor panel is added when you install the OS X Developers tools - I assume you didn't install that on the MacBook Pro.

Interesting finding about the whining noise

Hi,
I have like many others here a new MBP 2.0 with the whining noise. I have spent 2 to 3 hours those last 2 days with several support persons struggling for having the repair box shipped to me as repair seems the only option for me (I dont want and cannot wait 3 weeks more to get another MBP). FYI they were unable to take care of my correct address....Hmm not very good.
I have also done two interesting tests today:
1) I am part of the ADC and can have access to the latest builds of MacOSX. I have downloaded the current 10.4.6 build (8I1113) and installed it on another partition. I confirm that in this build, the whining noise is still present on my MBP.
2) I have also tested the Ubuntu Live CD (http://www.mactel-linux.org/wiki/Main_Page) and I was REALLY surprised not to hear any whining noise after ejecting the CD from the superdrive.
So my gut feeling is that the whining noise is probably a software issue rather than a hardware issue.
It could be interesting to get some feedback of people running Windoz on the MBP to check if they have also the whining noise in that case.
Any feedback ?

Seriously. do you even look at other threads before you post? lol. the whine that occurs the most has been diagnosed as a software problem. there have been many threads with ways to work around this problem. a couple links to threads that have software links or software suggestions in them are:

HP Pavilion DV2000 Laptop makes continuous "none stop" loud whining noise.

HP Pavilion DV2000 laptop makes continuous "none stop" loud whining noise. This happens when the computer is on and only stops if it is shut off.
The noise is very frustrating and just never goes away.
I googled for clues and read that proplems with the processor power management, something to do with AMD but the explaination were not clear and I don't want to ruin the computer. Here is a link to what I read. http://forum.notebookreview.com/showthread.php?t=192213
The sound is mainly coming from the left speaker area. So I disabled the sound card but the noise continues.
The fan appeares to be working well and no over heating.
Any clues as to how I can make this stop?
Thanks everyone.

The fan is so loud that when I have people around me they always ask me what's wrong with my computer. I bought it about 2 years ago but the warranty was only valid for a year and the fan problem got really bad after a year so there was nothing I could do about it. My old Toshiba, which is now more than 5 years old and which I had given to my brother after buying the HP, is still going strong and its fan, even during a hot summer day and while running some rather powerful graphic application on it, is never as loud as the fan which is normally on at all times on the HP. Besides, right after buying the HP and diligently doing all the updates that were recommended by HP Health Check, it died and I had to send it back to HP but because I was outside of the US, at the time, I had no computer for weeks until I returned to the US, got a free box from HP, shipped it to them and got it back. It didn't cost any money but it was a big hassle and not a very promising sign of future problems to come. Good luck to everyone who will buy an HP computer in the future. I am going back to Toshiba.

Power Mac G4 MDD 1.25GHz DP often completely locks up in the first few minutes after booting, sometimes with the spinning beach ball, normally with a very high pitched whining noise.

Over the last few months my Mac has developed a worrying habit.
Within the first few minutes of starting it up (perhaps on average about 50% of the time) it will completely lock up. This may happen at the Log In screen (if I start up the Mac & then leave it for a while) or during normal use.
Often the first symptom is a very high pitched (but quiet) whining noise that seems to come from the loud speaker on the front of the Mac. The pointer may freeze at this point, or it may still be moveable for 5 or 10 seconds before it freezes. It sometimes turns into the spinning beach ball during this. Once locked up the only way I can restart the Mac is to hold down the power button on the front for a few seconds to completely reboot the machine.
Once the Mac has restarted, it usually behaves normally, almost always for the rest of the day. The initial lock up & resulting restart only normally seem to happen the first time I use the Mac that day.
The only peripherals attached to the Mac (apart from the display, keyboard & mouse) are an ADSL modem, a USB printer and a pair of Apple Pro speakers, and this setup hasn't changed since long before the problems started, so I'm confident that I can discount the peripherals causing problems. I doubt that unplugging the speakers, for example, would have any effect.
I've run Disc Utility, OnyX and DiscWarrior without anything major cropping up. My instincts (I've been troubleshooting Mac problems for 16 years) tell me that I have a fundamental hardware problem, possibly with one of the 4 RAM DIMMs installed.
The RAM configuration is shown in the attached screen grab.
I'm considering removing one DIMM, running with 1.5GB of RAM rather than 2GB for a while, and repeating with a different DIMM removed each time until I can hopefully isolate the dodgy DIMM.
Do people feel this is a sensible approach, or should I try something else first?
Many thanks.

Sometimes visual inpection will show bulging tops/sides., my guess is if it is it's most likely in the PSU.
Possible cheap fix, You can convert an ATX PSU for use on a G4...

My iPod Classic is emitting a low whining noise and I can no longer access songs or audio books. Should I restore factory settings?

When I turn my iPod Classic on I hear a low whining noise coming from it.If I follow through the menus to a song or an audio book it shows the item for a few seconds then reverts to the previous menu and the whining noise is audible again. I have tried the "5 Rs" without success. Should I try restoring the factory settings - or is there something else I can do? I would be grateful for any advice!

I have the same problem with my ipod 4th gen 32gb! My music is all in the library but I cannot get it to go onto my ipod!! Ever since the latest iOS 6.1.3 update! I have restored my ipod, backed it up, done absolutely everything!! Nothing works! Please help!

MacBook Pro w/RD: Strange whining noise!!!

My Mac recently got serviced at an Apple Store - and there seems to be a problem. When I power it on, and while I am using it, there seems to be a strange whining noise coming from the upper-right hand side (when looking down at the keyboard). Near the Power Button! It's been drifting in and out of a local Authorized Repair Place, and the problem still is not evident.
It wasn't occurring before I brought it to the Genius Bar. I don't have a pentalobular screwdriver. They had gone into the machine and reset the EFI password at the Genius Bar. All help appreciated! Thanks!
I have a desperate project that needs to be completed before the 25th. I need this back (my machine) before January 22nd, 2013. Please keep that in mind when suggesting repair options.

Isit just when it starts up ? What about when entering a disc into the drive, do you get a almost crunching sound? If so, most definitely the optical drive. Mine is the same, nothing to worry about.. I haven't had any problems so far, sometimes when burning a disc I get errors, but nothing major.

Fan above Processor makes whining noise in 3000 H 105 M/T-8823-5AQ

I am having 3000 H105 series Desktop M/T-8823-5AQ in which fan above the processor makes whining noise when i use any heavy software or play Games. Also at the same time the CPU usages will reach to 90% - 100%. Please help my friend told me there is a problem in fan. And it may affected the Processor. The processor present in my desktop is Intel(r) Pentium D.
Anyone's ideas are greatly appreciated and welcomed.

This is not a problem, as the CPU fan varies its speed depending on the heat load of the processor, and one problem with variable fans is that they are quiter at low load and when it gets to high speed than the noise goes up exponentially, especially the OEM fan like yours. You may fix the problem by getting heat pipe design heat sinks from manufacturers such as ASUS, etc. These fans have a lower noise design large capacity fan, also the copper pipes have better heat transfer properties.
The pentium D processor use 2 pentium 4 CPU, so you can imagine the heat output of these processors, the large heat output from Pentium 4 is the major drawback of this design and premature abandonment by Intel for the far more energy efficient Core Duo and Core 2 Duo designs. If you are game enough you can try to poach a egg on specifically made heat sink on a Pentium D processor, which is not advisable.

Can Logic plug ins remove background noise from interview?

Can Logic plug ins remove background noise from interview?
A friend with an important interview recorded in noisy conditions has asked me to help remove background noise - never done this technically.
Is there a Logic or third party plug in that would could remove background noise from a spoken word interview? Have tried EQ which improves the sound slightly but not a solution.
Anyone with specialised knowledge of this sound editing operation?
cheers
MS

There are several 3rd party denoisers, they mostly work by first 'learning' the noise footprint of the audio, for which it is best to record a few seconds of silence (with an open mic).
These will all do a decent to excellent (it all depends on the source material) job:

http://www.kvraudio.com/get/2791.html
http://www.kvraudio.com/get/1182.html
http://www.kvraudio.com/get/1029.html
Addit:
Is it that background noise (traffic, talking etc) drowns out the words? Then you'd probably have more luck with (radical) eq-ing and/or notch filtering to find the most dominant frequency range of the speaker in relation to the background noise.
As an interviewer myself I will point out that even with a small disctaphone you need to have some awareness of how the microphone picks up things. As soon as you nead to lean towards whoever you're talking to, just to make sure you're audible, the dictaphone on the table is probably recording mainly ambient noise, the interview being part of that. This is especially a problem when interviewing in a busy public space.

My new iPhone 4 has no button to add calendar events and downloaded games apps make a whining noise when I open them. Any help welcome

Got an iPhone 4 yesterday and cannot add events in calendar. There is no + button and have searched in settings but cannot see how to do it.
Also downloaded game apps open with a whining noise that lasts for about 30 seconds plus. Had to turn volume off as its very annoying. Any help please

Did you try updating the firmware or resetting all settings
at: Settings -> General -> Reset -> Reset all settings?
It will not remove any data, just settings and things like ring tones etc

Magsafe plug pins stuck

The magsafe plug has 4 pins which seem to be on springs. The two middle pins are now stuck in and will not pop up again. Hence the macbook pro cannot be charged.
has anyone else come across this fault?

Other people have reported the problem. Are you interested in fixing the problem, or just taking a poll?

Satellite A660/15J High-Pitched Whining Noise

I have had a Satellite A660/15J for 3 months, running 64-bit Windows 7. The machine emits a constant high-pitched whining noise (rather like the sound emitted by early CRT television sets). The source of the noise appears to be the CPU (it is definitely not the cooling fan or the HDD). Is this a well-known problem? If so, how do I make it stop?

Since when do you notice this behavior?
I can only say that friend of me has Satellite A660 but without any strange noises. The notebook is quiet, only the fan makes some noises if its running.
For me it sounds like a hardware malfunction but before you contact an authorized service provider you can try to solve it yourself by updating the BIOS. This can be found on official Toshiba website.
If it doesnt help I would contact the ASP. The guys can answer you if its normal behavior or not.
