Imac spontaneously turning off while using iTunes?

Lately, every once in a while my iMac shuts itself down while inactively, listening to music from my library. Does anyone know what could be the course?

Specifically, I don't know the answer, but finding out the answer won't be hard.
We'll need a few specifics. You say your iMac shuts down while listening to music from your library. Is that the only time it happens? Is this when you're using iTunes, or some other application? What do you mean when your "iMac shuts itself down"? Does it shut down entirely, causing yout to reboot your computer? Could you describe exactly what happens before and after the "shut down"?

My iphone cut off while using itunes and now it wont work. it cuts on and off and it wont restore.

while putting music on my iphone from itunes my iphone suddenly cut off. it wouldnt come back on unless hooked up to charger and even then it turns on and off.. i have tried restoring it but it wont work. it actually restored once but it just started doing the same thing within an hour. every other time it errors out. what can i do?

Hi emfletcher!
If you have already tried restoring the iPhone, then the next troubleshooting step to address this issue would be to try putting the phone into recovery mode and attempting a restore from there. I have an article for you that can help you perform these steps:
iOS: Unable to update or restore

In order to fully troubleshoot and isolate issues, I would recommend not restoring from your backup after you finish this procedure. Thanks for using the Apple Support Communities!

Boot into Recovery mode, launch Disk Utility, select the startup volume ("Macintosh HD," unless you gave it a different name), and run Repair Disk (not Repair Permissions.) If any problems are found, repeat. Then reboot as usual.
If you don't already have a current backup, you must back up your data, if possible, before you take the above step. You may be able to back up, even if the system isn't bootable. Ask if you need guidance.

Imac monitor turns off while working

Hi everybody,
I have issues with my Monitor. Every now and then my Monitor just turns black or sometimes white with blue stripes, during working.
I have to restart it and everything works fine again. Unfortunately it happens more and more often.
Can anybody help me?
Thank you

IMac display turns off automatically.

Hi everyone!
I have a problem with my iMac. The display automatically turns off while using the computer and I can't continue using it without forcing it going to sleep. The display turns off when the screen brightness is NOT at maximum level. If I reduce the brightness, the screen turns off. If the display it's at the maximum level, no problem, works perfect. No matter if the computer is just turned on from a cold start or if it's running since hours with high temperatures. In System Preferences there's only one option selected in the Enegy Saver section (Allow power button to sleep the computer).
Any ideas? It's really annoying working with this problem (especially at night with the brightness at maximum).
Hope somebody can help me!

Well-used iMac suddenly turning off

My not-so-new 20" iMac is turning off on me. I have used this computer, many hours a day, for several years now. For the past 20 months, I've lived in an apartment with old outlets that haven't been replaced, and don't have great contact with the electrical plugs. I've been using a power strip, and the computer only turned off when someone knocked the plug out of the outlet or bumped "reset" on the power strip.
Starting yesterday, my computer started turning itself off (apparent power failure) without anything getting bumped. I'm not seeing any changes in the lights around, me, either, so I don't think that power fluctuations are the proximate cause. I've fiddled with all of the pulgs, unplugged and replugged them, and the problem is getting worse: my computer is shutting off more often. I'm using my spouse's laptop to ask this question, because it's gotten to the point where my comptuer really isn't useable. I've gotten great advice from these forums before, and I'm looking forward to getting good advice this time.
Could a power regulating power strip solve my problems? I'm guessing no, but should I do this in the future, to prevent damage to my computer? More importantly, what is likely wrong with my computer, and about how much would it cost for me to replace the part, or get it fixed at the Apple store? I did not purchase any extended warranties, so this computer is completely out of warranty.

It's been a month since I first posted, and I've got more clues and details now. After I posted my question I realized that my computer is and has been on a surge protector (and the protector light is light), so on later reflection I don't think the problem is the steadines of the power.
den.thed's suggestion seemed to work at first, although I think the longest my computer has gone without shutting down in the last month was about a week, and at this point resetting the SMC doesn't seem to be helping (not that I've turned the computer back on without unplugging it, so I haven't tested this precisely).
I leave my computer on at night (sometimes I put it to sleep, sometimes it puts itself to sleep, but sometimes something happens and the computer doesn't put itself to sleep, or my cats step on the keyboard and wake it up), and it has not shut down at night. It only shuts down when I'm sitting in front of the computer, using it. This made me think I might be having a software problem, so I tried avoiding using specific programs, but I can't isolate a specific program that is always open or always being used when my computer shuts itself down. I think my computer has only shut down while I'm typing, but I'm not certain on that one. I'm using a logitech wireless keyboard (because I spilled water on and destroyed the original keyboard), and (because I only have the one keyboard at the moment) I haven't tried using another keyboard.
Last night I had the realization that the times my computer was going longer without shutting down was when I'd unplugged my backup HD running Time Machine (because of the limited number of USB connections on the computer). I am not certain if my computer has ever shut itself down with the external HD attached. I have had successful saves to Time Machine on my external HD while dealing with this problem.
But these two clues: maybe shutting down only when external HD is plugged in, and definitely only shutting down when when I'm sitting at the computer, actively using it, don't seem to me to point to the same problem.

Since I upgraded to OS 10.6.8 from 10.5.x my 2x3GHz quad-core Intel Xeon desktop spontaneously turns off as if I pulled the plug. Mostly it happens when there is no open software and it's in the sleep mode, but it has happened while I'm working.

Since I upgraded to OS 10.6.8 from 10.5.x my 2x3GHz quad-core Intel Xeon desktop spontaneously turns off as if I pulled the plug. Mostly it happens when there is no open software and it's in the sleep mode (because it spends more time like that), but it has happened while I'm working. It just suddenly quits.

This is a suspicious sign of power supply failure. I would have that checked into. Others who have had similar problems have had the power supplies replaced which fixed the issue.

Not enough free storage space can slow your Mac down. Click your Apple menu icon top left in your screen. From the drop down menu click About This Mac > More Info > Storage. Make sure there's at least 15% free disk space.
Anti virus software, as well as third party Mac cleaning utilities such as MacKeeper and CleanMyMac can also slow your Mac down.
Check to see if the startup disk needs repairing.
Launch Disk Utility located in HD > Applications > Utillities
Select the startup disk on the left then select the First Aid tab.
Click: Verify Disk (not Verify Disk Permissions)
If DU reports errors, restart your Mac while holding down the Command + R keys. From there you should be able to access the built in utilities in OS X Recovery to repair the startup disk.
Make sure to back up all important data first before using OS X Recovery.

How do I turn music completely off while using maps

How do I turn the music off while using apps for directions. Every time I use maps to navigate somewhere I get music that comes on automatically anyone know how to turn this off?

Just disabling firewire at the system settings not physically shuts off power to the firewire port. And since you feel by yourself facing a hardware defect, I would recommend taking the computer to a repair center.
Maybe they are able (I'm absolutely not sure about, but sometimes hope dies at last to remove an internal cable and so shut down the firewire ports without replacing any expensive parts.

It's been power cycling (turns off while in use) with increasing frequency, and now won't even turn on. What gives?

My phone has been turning off while in use, and would, in the past, recover if I turned it off and on.
Now it won't do anything, and I know that the battery is not dead. What gives?

Hello Hoges,
About your question of connecting the Elitepad directly to another PC via USB.
Since the tablet is considered a full windows PC, you cannot connect it directly to another PC via USB.
Androids and Apple iphones, etc etc. are different than a windows PC. Even if you used an OTG usb cable.
Windows PC's could be connected via a crossover cable but it is very particular and requires an ethernet port on both machines.
You can connect them via a Network though, like connecting via a Home Group through a wireless connection.
Better still, you can backup your files on a cloud service like Dropbox, Onedrive or Google and then download them to the other machine. If both machines are using Windows 8.1, you can use HP Connect to backup and transfer files.
If you have a usb to micro usb adapter, you can use a pen drive to tranfer files with.
I do not know anything about the magazine articles you are downloading, but if done so via an app in the Windows store, couldnt those be redownloaded anyway without transfering?
IF the tablet is still under warranty and the charging port is loose, you can contact HP Support to see what your options are.
Hope it helps.

IMac turns off while sleeping

My iMac sometimes turns off during sleep mode, I did call apple care and went through utilities and the tech support said that issue should be resolved, but it happen again today. Has anyone else had the same issues? Is this also the start of some bigger issues down the line?
Thanks,

HI BC,
Check System Preferences/Energy Saver. Click the Schedule button bottom right in that pane and make sure it's not set to turn off at a certain time.
According to this article, http://support.apple.com/kb/HT1237 Make sure your software is up to date.

How can I turn off genius in iTunes 10.5.3 (3)

How can I turn off Genius in iTunes 10.5.3 under Lion 10.7.3 (other than disconnecting from the internet). It is no longer an option in the Store menu and although I can hide that playlist on the left through parental controls, the atom symbol is still present in the lower right of the window available to generate a list from a selected song. Thank you.

I have the option to turn it off. What version of iTunes are you using? I have the latest iTunes. Have you tried signing out of the store?
