My mac makes a loud humming sound

My mac makes a loud humming sound when i turn it on. The sound is from the base of the MAc and it sometimes get really hot.

Resetting SMC as well as blow out the dust could solve the problem.

IPod: Screen Freeze, Loud Humming Sound

With two different 8 GB iPhone's, I have experienced the same freeze while using the iPod feature. When I began to play a song, the iPhone froze on the album art screen of the song playing and played a loud humming sound that could not be shut off without a soft reset.
Unfortunately, the soft reset took over one minute to shut the phone off, and the loud humming sound cannot be shut off until the phone powers off. Has anyone else experienced this problem, and has anyone identified how to prevent the phone from freezing like that in the iPod mode?
Thanks!

There is a bit more errror information available if you can read out the full kenel panic log and post the TEXT here.
Readers who study these things will come along and help determine possible causes. If you are getting multiple kernel panics with no underlying trend, that can be caused by RAM memory problems. The Mac Pro (65lb tower) uses Error Correcting Code (ECC) Memory, so its memory symptoms are quite different.

hi there smallworld100,
could you provide the community with a little more info to help narrow troubleshooting? Mainly your printer model but things like your operating system as well will help out a lot.

New Mac Mini making loud clicking sound

I bought my Mac Mini (Late 2012) in August 2013 and from the first week of having it, it periodically makes a loud 'click' noise followed by a series of 'tick tick tick' noises. This is usually accompanied by a slight hang in any .app I'm using and my iTunes will cut out momentarily. Sometimes it happens when I'm not doing anything on it at all.
Is the hard drive failing, and why on earth would that be an issues in a brand new computer? Am I going to have to take it in for repair, as it's my only computer for work?!

Dead on arrival hard drives are nothing new. Even my folks had a Dell with one. Transportation in an unpadded cases can also jar a hard drive, though usually the parked heads prevents any damage. You should always be backing up your data regardless:

At least you are under the 1 year hardware warranty. Buy AppleCare before that runs out, and that way you will be covered until 3 years from date of computer's purchase.

Ipod makes a clicking/humming sound

I just bought a 80gb video ipod a week ago and i just recently noticed that when i use the controls or when it finishes playing an album, I can hear a faint clicking and humming sound. I'm assuming this is the internal hardrive but it does it quite often. Is this anything to worry about?
Sony VAIO notebook Windows XP

I get the same thing when playing videos. I'm really frustrated with this...when i fast forward twice in a video, it makes these clicking sounds and after the 3rd one, the Ipod crashes. It's really annoying, I should have waited for the zune if this is the case. There were no recent updates on the firmware since I bought my new 30 gig in the apple store. No freaking firmware realease, everybody thinks that it'll be fixed with an new firmware update, but they never did have any new updates since the 5th gen release. SOB. I hate this product!

Ibook makes a loud whurring sound...

Perhaps someone could help. I just bought a used ibook G4 and it was working perfectly fine until I replaced the power adapter (unfortunately I stepped on the other one and ripped the cord). The model of the adapter is supposed to be compatible for both the powerbook and ibook, BUT as soon as I got it home and turned it on, it was working for two minutes, then the screen went black and it started making this really loud whurring sound. I immediately shut it off and waited and then tried to restart it manually and at the startup it sounded ok and then the whurring sound began again, and the screen stayed black. I tried to hold down the option + command + P + R and then shift but there was still nothing. Is my computer shot or is there a chance I can get her going again? Please help! BAH!

Nano won't respond makes high pitched humming sound when hooked to cable

I'm beginnign to feel jinked. lol This is the second Nano I've had since October. The first was returned because of a defective battery and promptly replaced. Now to the current issue.
This Nano has acted erratic from day one. The hold button malfunctioned immediately, but functioned sporadically. It would not "hold" the Ipod when I turned it on and the hold icon wouldn't appear when this happened. Then it appeared to never actually turn off when I tried to turn it off, although it would have a blank screen. Instead it appears to go into pause. This is proven out by the fact that the battery power goes down quickly from use to use. Then it just faded out and died as if the battery was drained. BUT, the computer (all three of them) wouldn't recognize the Nano when hooked up to the charging cable it came with. Now it is emmitting a high pitched humming noise, has a blank screen and the computer still won't recongnize it.
I sent this Nano back already for repairs. It was returned to me UNREPAIRED with a note saying no problems were found. There is ABSOLUTELY something wrong with it but unfortunately for me it decided to come on right before I shipped it to Apple. I assume that is why it appeared to be functioning.
I have yet another repair request in for it but my confidence level about it's eventual repair or replacement is sinking. The most frustrating part of this is I LOVE this product. It was a greatly appreciated addition to my workout routine and other music needs. Any advice would be greatly appreciated.

I forgot to say I tried the 5 r's, called tech support, have been ALL over this forum, and have even asked other nano users I know for tips.

My printer makes a loud dinging sound every 5 seconds.

I have no error messages and it prints perfectly. I have restarted the printer and computer. I have unplugged the printer but can't get it to stop dinging.

Humming sound ...

Hi,
My iMac 24" makes a loud humming noise when I turn down the brightness (gets louder the lower the brightness)
Is this normal ?

An update ...
I have today received my replacement iMac 24" and am a bit dissapointed ...
The box looked a little tattered when it was delivered at work, so I opened it up only to find that it has scratches/scuff marks along the top of the case and black marks on the front, the iMac appears to have been opened up at some point. Unfortunately the courier had left so I could not refuse to accept the parcel.
I booted the iMac up in the office to see if it had the hum / tone when the brightness is adjusted. In the office environment it was inaudible, however there is a lot of background noice with air con and other PC etc.
I got the machine home tonight, and decided that although it needs to go back I wanted to see if it has the same 'tone' problem.
In my quiet study the tone (I've stopped calling it a hum) is quite evident. I can hear it clearly over the top of the fish tank air pump.
I'll be back on to Customer Services when they open in the morning ... what a downer

Humming sound from Mi

I recently upgraded to firmware version .0.02. My Micro was working fine till I turned it on from "deep sleep" (more than 4 hours) this morning. It froze on the "Zen Micro" screen and produced a loud humming sound (ZZZZZZZZ) through the earphones. I took out and reinserted the battery to reset the player and turned on the player. This time it froze at the "Rebuilding Library" screen and still produced the humming sound. I left it alone till I came to work and connected it to my computer and it rebooted, rebuilt the library and started working fine. I doubt it's a low battery problem because when it started working, it had 3 bars left.
Anyone else facing this problem? Hope it does not happen again...

There is no fan in hard drives. However, given there are rotating platters it is possible to get what is much like a blowing sound from them. It's actually the noise of the spindle bearings and is a rather distinctive rotation sound.
Depending on the volume of this noise Apple may or may not do anything about it as it's very subjective. Having sensitive hearing I find that most drives make some spindle bearing noise or other. In a quiet room I can distinctly hear mine.

My ibook G4 won't start it shows black screen and loud fan sound only

my ibook G4 won't start, after you press the on key it makes a loud air sound, almost like a kernel panic sound, no screen light just the sound, it will turn off by pressing the on key again. Is there anything I can do to get it on?

Your very welcome.
You would need to apply pressure to the left side of the track pad about 2cm out. I found applying pressure to both sides of the track pad more successful. All you have to do is push down on the case, while making sure your iBook is on a flat surface. If you have someone willing to help you, you can get them to apply the pressure while you back up your files. Other methods would involve tempory repair or removal of the hard drive. If you remove the hard drive to be read by another computer, you would need a cady to put the drive into. These caddies are cheap enough. Would suggest you use a USB cady and plug your drive into that, which would act as USB external drive. I'd suggest you get a USB cady to remove your files, be careful to what operating system you have on the computer you are using to get the files off. Windows OS won't read a MAC OS X drive (extended journal format) It would need to be another Mac or a Linux PC.
If removing the hard drive is something your not to confident in doing, you could alway pay a computer repair shop to remove it for you. (Maybe they would have a USB cady for a 2.5 IDE hard )

Let's hope just applying enough pressure is enough to get your files back up.
Best of luck!

W2207h monitor has loud hum or whine

My monitor suddenly developed this loud hum or whine. I am afraid to leave it on so haven't let it boot up completely. What could cause the noise? Is it repairable? Could I repair it myself, or does it require a professional? What would it probably cost? Should I simply buy a new monitor?

Hello Danpw,
Your monitor makes a loud hum or whine, is that correct? I will try to help you.
I have seen a possible fix of increasing the brightness you can try that.
If the monitor is still under warranty you need to contact the HP support desk to set up a service for a replacement monitor. If you are not sure about your warranty insert your monitor information in to this document to confirm.
Please respond back at your earliest convenience.
Thanks
