IMac suddenly shut off.
I was using my iMac earlier today when it suddenly shut off. The only programs I had opened were Safari and iTunes. I put my hands on top of the computer and noticed that it felt especially hot. Could the cause of my iMac shutting off be because it got too hot? Should I be concerned about possible damages that may have occurred? I appreciate your help.
One more thing; my iMac won't go to sleep according to the inactive time that I have specified in the Energy Saver settings. It only goes to sleep when I access the sleep command or push the power button. Otherwise it just stays on. Thanks again.
Thanks for all your replies, guys. I hadn't logged in since Monday so I didn't know that there had been more posts since then. Anyways, to address why there hasn't been a recall or any public recognition of the problem (that I know of), I have a theory: after all the Apple commercials that basically boil down to "Macs are better than PCs because Macs work," how bad would it look that they would have to do a major recall on these new iMacs?
This is actually my first Mac. I was really stoked about it because everyone that I spoke to that had owned Macs never had any complaints. I'm getting a little concerned now. We've spent good money on these machines and apparently for a lot of us they are turning out to be a major headache. If I wanted a computer that performed poorly I would have bought a PC and spent half the money (sorry to all the PC guys out there. I've had some bad experiences with PCs that helped fuel my decision to purchase a Mac).
Anyways, I've had another unexpected shutdown earlier today so I'm going to call Apple again and see what they say. For any of you who are having this problem and are going to call Apple for the first time, your support may go something like this: turn the computer off and turn it on again holding the Command, Option, P and R buttons simultaneously. Then, using the Disk Utility, you will verify the disk. Mine claimed that everything "seemed" to be okay and as of Monday I was to monitor my system and call back if it happened again. I'm going to call them again and I'll let you all know what they say.
Dennis, thanks for the link. I have not read it yet, but I will. I'll keep you all updated. Thanks again and good luck to all of you as you try to get your Mac issues resolved.

While working on my iMac, it suddenly went off. No warning at all. I've tried all the basic stuff and nothing happens. Holding the power button in and I don't hear the normal sounds. Thought it might have overheated but after it's cooled down, still nothing.
jsteinmi wrote: This iMac is only about 8 months old.
It is still under warranty, so a trip to the Apple store is in order. Don't do anything to it! Just take it to the Apple store or the store where you bought it.
I suspect it is a problem with the PSU and it is not user serviceable. Just pack it up and take it back. -
After I upgrade maverick my display will suddenly shut off but my sounds is still working. Need help on this? Thank you
Hello rodamitjr,
It sounds like your iMac display will turn off unexpectedly, but you can tell the computer is still on because you hear audio.
I found an article with steps to troubleshoot issues with displays. This article is for internal and external displays, so you can skip any steps referring to an external display. I recommend reviewing the full article, but this step specifically stands out to me for the issue you described:
Reset the system
You can reset the Mac's parameter RAM and SMC.
You can find the full article here:

Thank you for posting in the Apple Support Communities.

IMac G5 Shutting off by itself
My imac G5 second generation is all of a sudden shutting off by itself in the middle of me working on things. The unit is not overheating or making loud fan noises when it does this? What should I do?
JasonTake the back off and check out the LEDs using the instructions [here|http://docs.info.apple.com/article.html?artnum=300908].

IMac G5 shuts off and won't restart
Mac suddenly shuts off, and won't restart. Begins to boot, but shuts down again, sometimes after only a few seconds and before the chime, sometimes after 30 seconds, sometimes after several minutes. After many attempts, can sometimes get restarted. If I hold in the power button, I get a long tone, and then sometimes get a gray screen with Linux style text, and if I type mac-boot as prompted, it will usually reboot. Then its good for a day, or several days but eventually, will go off and I can't reliably get back to that gray screen with text.
Not a techie, or Linux fluent...just got there by accident.
Is there something I can do / reset / or replace to fix this? (Yes, I know the computer's old, but I'm not ready to go to the Intel chip and the expense of repurchasing all my software yet!!)
Thanks for any help.I have the same 1.8 GHz iMAC G5, and had the same problem of the computer shutting off abruptly, and then not starting up - shutting down after the chime, or sometime during the start-up process (I don't know about the gray screen - never tried that). Eventually the computer just wouldn't turn on at all - now it's dead.
I found this Apple support article recently, which shows how to diagnose a dead iMac G5, to see whether the computer has a bad power supply or a bad logic board. It might be helpful - in my case, it points to a bad logic board. Maybe both are bad (?). The procedure is for a dead computer, but maybe it would show something in your case too.
http://support.apple.com/kb/HT2173
Good luck. I don't how much it would cost to put in a new logic board or power supply. I love the monitor on the G5 iMac (beautiful non-glossy), and I wish I knew of a way to use the monitor by itself. -
my ipad 2 suddenly shut off and asked me to connect to itunes it asks me to restore but it wont work need help pls
The iPad is telling you it has entered the recovery mode - you need to follow the instructions in http://support.apple.com/kb/HT1212 for connecting to a computer running iTunes by way of the recovery mode.

Keyboard lights suddenly shut off
I'm a noob with an early 2011 MBP 13" i7 running Lion and I've noticed that the keyboard backlight has started to suddenly shut off randomly.
It's only happened a couple times and the last time it did I actually could turn it back on by pressing the correct button, but the time before that I had to restart the thing.
Am I crazy or is my mac posessed?Hello Dave the Revelator!
Have you checked in the System Preferences > Keyboard > Keyboard "automatically illuminate keyboard in low light"? If yes, it is normal. When the light sensor is receiving bright light, the keyboard lightening is switched off.

Thunderbolt Bus: MacBook Pro, Apple Inc., 22.1What you should do next depends on the circumstances. For example:
If you installed the keylogger yourself and then forgot about it, remove it according to the developer's instructions. If you want to keep it, check for an update or refer to the developer for support.
If you're under 18 years old, and the keylogger was installed by a parent or guardian, talk it over within the family.
If you're an adult, and the keylogger was installed on your personal computer without your permission, then the computer may be evidence of a crime or a civil wrong. Consider the legal implications before you do anything. Assume that everything you've done with the computer is known to the party who installed the keylogger.
If the computer was issued to you by a school or employer, then you should check with the IT staff that the keylogger is authorized. Don't use the machine for personal business. If the keylogger interferes with your work, the IT staff will have to solve the problem.
In the event that the computer was tampered with by an unknown party, and you just want to clean it up, see below.
The only way you can be sure that the computer is not compromised is to erase at least the startup volume and restore it to something like the status quo ante. The easiest approach is to recover the entire system from a backup that predates the attack. Obviously, that's only practical if you know when the attack took place, and it was recent, and you have such a backup. You will lose all changes to data, such as email, that were made after the time of the snapshot. Some of those changes can be restored from a later backup.
If you don't know when the attack happened, or if it was too long ago for a complete rollback to be feasible, then you should erase and install OS X. If you don't already have at least two complete, independent backups of all data, then you must make them first. One backup is not enough to be safe.
When you restart after the installation, you'll be prompted to go through the initial setup process for a new computer. That’s when you transfer the data from a backup in Setup Assistant.
Select only users in the Setup Assistant dialog—not Applications, Other files and folders, or Computer & Network Settings. Don't transfer the Guest account, if it was enabled.
Reinstall third-party software from original media or fresh downloads—not from a backup, which may be contaminated.
Unless you were the target of an improbably sophisticated attack, this procedure will leave you with a clean system. If you have reason to think that you were the target of a sophisticated attack, then you need expert help.
That being done, change all Internet passwords and check all financial accounts for unauthorized transactions. Do this after the system has been secured, not before. -
Suddenly shuts off, turns on (completely reboots)
Hi,
I have a Macbook Pro (15-inch, early 2011). My computer suddenly shuts off (fully charged, plugged in, no warnings of low battery or anything). When I turn it back on, it reboots completely (as opposed to restoring my session like it usually does if the battery dies) and says the battery is at 0%. This has happened a few times now. Does anybody know what it is or how to fix it? Thanks in advance!

hello everybody,
I have an iMAC G5 20' and I just update the system with Tiger X.4.7 a week ago and since then my iMac is shutting off abruptely by himself without any warnings. It happens two times last week and tonight it happens twice.
The overall temperature of the Mac seems correct
Anyone has any idea ? I already saw that some MAc Book users seems to have the same problem !
Any comments ? Thanks for your help
JipesHi, Jipes.
Could be a power supply problem or an issue with mains power: assure the power cord is connected properly to the computer and mains power, and that the power cord is undamaged. Try a different power socket. If you use a UPS, be sure the battery is good.
As far as general iMac G5 troubleshooting goes:
1. See if your computer's serial number is in the range specified in the "iMac G5 Repair Extension Program for Video and Power Issues" document.
2. Rule out potential hardware problems. Run the Apple Hardware Test that came with the computer. Instructions for doing so will be found in the hardcopy manual that accompanied your computer. For additional details, see my "Apple Hardware Test" FAQ.
3. Check the diagnostic LEDs, a feature of your iMac G5. See "About the iMac G5 diagnostic LEDs."
4. If your iMac G5 will not turn on, see "iMac G5: Troubleshooting when your computer won't turn on."
5. See also the iMac Service & Support site.
6. Check the iMac G5 Discussions for similar reports from other users.
7. As a general check, run the procedure specified in my "Resolving Disk, Permission, and Cache Corruption" FAQ. Perform the steps therein in the order specified.
8. If the computer is either under warranty or covered by an AppleCare Protection Plan, don't hesitate to take advantage of your warranty and contact AppleCare.
Good luck!

My imac suddenly shuts down while on line.
My imac suddenly shuts down while on line. It has to be unpluged for a couple of hours before it will restart. Could it be the battery dying? Any other sugestions?
Which iMac..? Go to > How to identify iMac models
1. Reset the SMC > Intel-based Macs: Resetting the System Management Controller (SMC)
2. Reset the PRAM and NVRAM > Resetting your Mac's PRAM and NVRAM
Then test it for a time and report back.
You also might want to give the Extended Apple Hardware Test a run, as per > Intel-based Macs: Using Apple Hardware Test to see if it turns up a hardware problem. -
My 27inch iMac automatically shuts off
My 27 inch iMac will shut off automatically after about 30 to 45 minutes - it will not turn on when using the on/off power button. I have to unplug from the wall, hold down the on/off power button for 10 seconds, plug it back into the wall then usually, it will turn on. I have tried using different wall outlets and not using a power strip but unless i follow the previous steps, it will not turn on. I ran an apple diagnostic test - it showed no issues with the hardware. It was purchased from the apple refurbished store in April of 2013. For hardware -processor 3.2 GHZ quad core intel core i5 - memory 8GB 1600MHz DDR3, graphics - NVIDIA GeForce GTX 675MX -software - OS X, iLife '11
I think you should have received a 1 year warranty on this Mac, so I would take it in and have them fix it for free. If this is happening routinely at about the same time after boot up it sounds like an overheating issue, which is most likely hardware related.

Why is my Macbook suddenly shutting off?
I have a Macbook (A1278) and in the last couple of days it has started suddenly shutting off without warning.
The screen goes black and I have to press the power button to turn it back on.
This has happened both when the battery is full and when the power cord is attached.
There are no other problems that I have encountered in performance or otherwise.
The fully charged battery lasts 2 hours which is pretty good considering the computer is 5 years old.
Could this be a sign that I need to replace the battery? Or is something else the matter?
Solutions, advice or comments are greatly appreciated.Run the hardware test that came with the machine. Boot off the 'D' key. If nothing happens, you need the original installer discs to run it.

Hi,
Since a while my iMac suddenly shuts down and reboots.
It starts with a frame freeze, can't move the mouse cursor. After a few seconds my iMac shuts down.
I have no idea what the problem can be.
This is the report of Console when it shuts down.Hey MagicMarcus,
Thanks for the question. I understand that you are experiencing issues with your iMac unexpectedly shutting down or restarting. The following resource provides some great information if this happens, along with potential resolution steps if it is a reoccurring issue:

The volume on my iPhone is working intermittently (keypad tones, ringer, etc...). There seems to be no rhyme or reason or common denominator to when or why it suddenly shuts off. Any advice?
The problem is pin corrosion on pin number 21. It is ver simple to clean out. Google "where is pin 21 on apple dock connector." Then get a pin or dull needle and gently pull it over pin number 21. You won't see the corrosion on the pin or even see it come off, but it works.
