What's the clicking noise?
I've had my MBP for about a month now and so far all has been well and good. However in the past week, I have started hearing occasional clicking noises coming from the left hand side - it almost sounds like an electrical spark. I say occasional, but it is in fact, every twenty seconds or so.
Anyone else getting this?
Just ran the hardware test and got the 4SNS/1/40000000:'TmOP' error. Is this the logic board?
Thanks for any advice..

my ipod is showing nothing on its screen only a white blank page, i can hear the clicker noise but i cant see anything it really ***** because i do not know what songs to choose!!!
Hi j131v,
Welcome to Apple Discussions
You may want to try resetting your iPod (Knowledge Base Document #61705 on How to Reset iPod). Have you tried "The Five Rs". Is this (Knowledge Base Document #303130 about iPod "stuck" on the Artwork or Rating Screen) your problem?

My iphone dosen't doesn't make key tone sounds anymore when I write a text message or when I want to dial a phone number I don't know how to fix this problem, I don't hear the clicking noise anymore does anyone know how to fix this problem?And all the sounds on my phone are on, even the keyboard clicks.
Try restarting your iPhone by holding down the on/off and the home buttons at the same time until you see the Apple logo, double check the volume button just in case. If you still can't hear the tones go into your settings>sounds and make sure the options are on.

What is the "Random Noise" specification in the AI Absolute Accuracy Table
I have a PCI-6255 board that I'm planning to use for some sensitive measurements.
I'm trying to put together an end-to-end error budget and I have a couple questions.
My model is in terms of analog-to-digital converter counts (also known as LSB in your data sheet).
In the Absolute Accuracy table on page 5 of the NI 615x Specifications I see a column labeled Random Noise, (uVrms).
I think I understand the residual gain error, residual offset error, and associated Tempco, and the INL error but the Random Noise is puzzling me.
Here is why: on the +/- .2V range, the random noise is 16 uV. On this range, the ADC resolution is 6.1 uV so the random noise is about 2.6LSB
If I look at the +/-5V range I see a random noise of 140uV. On this range, the ADC resolution is 305uV so the random noise is well under one LSB.
Therefore, in my error budget I can use "1 LSB" for the random noise when on the 5V range but I have to use "2.6" or "3" LSB when on the .2V range.
I expect a signal of aproximately 150mV riding on a 2.5V DC level. I was concerned I might need to offset the signal (remove the 2.5V dc) in order to use the +/-.2 volt range to get better resolution. I also thought I would get better noise performance too. In looking at the numbers here though it looks like I would be better off using the +/-5V range (assuming it gives good enough resolution) because the readings have less noise counts (even though it is more noise volts).
I can account for the Gain Error and Offset Error by injecting known signals and doing a "software correction". Not sure, but I believe I can also correct for the INL if I use a polynomial fit of 2nd or 3rd order. It's the random noise I'm having problems understanding.
Here's the question: what is the Random Noise shown in the AI Accuracy table for the 625x boards? Can you give an example of how NI might have measured it?
Secondly, note 2 says "Sensitivity is the smallest voltage change that canbe detected. It is a fucntion of noise." Was this measured with a signal-to-noise ratio of "1" or "2" or some other standard, or is this a calculated value?
Thanks

What is the fluttering noise coming from my desktop?
what is the fluttering noise coming from my desktop?
Probably a fan. Could be hard drive noise, a CD or DVD that has a label on it.
Can you describe the sound more fully, what it sounds like, when and how often it occurs? -
What's with the CLICKING noise after every edit?
In the latest version of GB, whenever I make a simple splice to a voice track, there's a CLICK artifact at the tail of every edit. In order to remove it, I have to zoom in and really play with the length of the clip to get rid of the click. This is REALLY annoying because I know I'm not cutting during an active waveform. In other words, there's "silence" when I make the cut, yet I keep getting an audible CLICK every time. The old version of GB did NOT do this. A clean cut was a clean cut. This is obviously a bug. Does anyone know of a workaround to avoid this artifact? Thanks!
Generally speaking it's:
720x480 @ 29.97 fps for NTSC (or 23.976 for NTSC Film)
720x576 @ 25 fps for PAL
Anamorphic video formats (e.g 16:9 aspect) is accomplished either by (rarely) scaling the image down and including black pixels at the top and bottom of the image, or (usually) by the setting a flag which tells the DVD player to stretch the pixels horizontally, scaling the image and automatically adding black at top and bottom if needed.

What are the phase noise specifications for the 10 MHz internal reference in the PXI-5661?
Im looking for the phase noise specification on the 10 MHz internal reference for the PXI-5661.
Hello Bob,
As you may have noticed, and the likely reason for this post is that that spec is not readily available for the PXI-5600. You will however notice that the overall phase noise of the system is noted and my suspicion is that even though the 10Mhz reference helps improve the overall phase measurement, it won't necessarily dictate the measurement. I can ask R&D for this spec but they will likely inquire the need for this specification. Do you intend to use an external source instead of the built in reference?

HELP
It's not designed to work like this. When you sync, the iPod stores some information that basically says 'this iPod belongs to computer xyz'. Apple did this to prevent copyright issues (syncing someone else's music).
If you really want to do this, you'll have to at least tie both iTunes installations to the same account. Maybe have them sync with each other. -
So my late 2012 MacBook Pro was sitting on my desk when the desk collapsed. The computer fell with it and I was quite scared at the moment, but thankfully I opened it up and it worked perfectly fine again.
I was later watching a YouTube video and pressed the back button. The screen then froze, and I could not force quit safari. Then this weird clicking noise started to happen. It was coming from the right of the trackpad. That's when I decided to force shutdown the computer with the power button.
I let it sit and then decided to turn it back on. The clicking noise then came back and there was just a blank screen on the boot up. Eventually a grey folder with a question mark started flashing on the screen. That was all it did so I decided to turn it off again.
I'm going to take it into the Apple store ASAP, but I'm curious if my hard drive is damaged and if I will need a new one, which would erase everything on my Mac. So I was wondering if there is anyway to back up the hard driver even if it doesn't boot up all the way, or turn on the computer all the way.
P.S. I have never backed up my hard drive so I wouldn't know what to do.You may have damaged the HDD which is located in that spot. I would take it in for service.

My MacBook Pro 13.3 MAC OS X v10.7 laptop will not come up. Blank screen comes up, no color/desktop, etc., only an icon of a folder in the middle of the screen with a question mark on the folder. Laptop making a clicking noise. Suggestions? Thanks!
It's under warranty. Take it in to have Apple fix it.
The "flashing ?" means the machine can't find the start up disk. The clicking noise is a give away that the drive is damaged. -
Satellite U500-1E0 - how to switch off the mouse 'clicking' noise
Please can anyone tell me how to switch off the 'clicking' noise that the mouse buttons make when they're depressed?
Thanks.Im not U500 owner but Ive got a U400 notebook model.
As far as I know the touchpad buttons dont support any clicking sound which could be enabled or disabled by software.
Therefore I would say its a mechanical noise which cannot be disabled.

Can you turn off the Sleep/Wake "click" noise on an iPhone 5C?
Is there a way to turn off or change the "click" noise when activating the sleep mode on an iPhone 5C as it can be distracting and/or annoying?
I am running the current iOS (8.1.3) and iTunes.Yes. It's under Settings/Sounds/Lock Sounds (you'll have to scroll all the way down to the bottom of the page to see the setting). Disable/turn off "Lock Sounds" and you should be all set.

Ipod makes clicking noise and won't be recognized by itunes.
I've had this ipod for about 2-3 years (5th generation 30 GB) and all of a sudden it started making clicking noises when i started it. So i connected it to my computer and all it does is (1). Start up with the Apple Logo (2). Make that clicking noise where it sounds a ticking clock. (3.) Please wait, very low battery. (then it goes forward after) (4). Shows some icon with an ipod with dead eyes ( x.x ), emergency icon and it says www.apple.com/support/ipod. Please answer because i have over thousands of songs and i dont have them on my itunes ( i transfer the songs to my itunes. then my ipod but then i had to reformat it and so the songs on itunes are gone and i have only my ipod)
ive got excatly the same problem, my pod (also had it 3yrs 30gb 5th generation) has started making the clicking noise, i get the apple symbol appear or the sad looking face, im unable to restore it and i think the sad face may mean its a hardware problem from wot ive read on the online support. but i dont know what to do or where to send it to be fixed or if it can be fixed, if you find out how it can be fixed please let me know its doin me head in.
