My macbook shuts down automatically after 30 seconds of inactivity

after immediately start up, maybe less than 30 seconds, the menu comes up asking if i want to restart/shutdown/sleep/cancel and if i don't cancel immediately the computer shuts down.
if i cancel, the menu shows up after about 30 seconds.
i have checked the energy saver prefs and everythign is set at 15 min.

Update: I found the problem in similar posts. Once I inserted the headphones completely in (no metal showing), the problem was resolved.

MacBook shut down automatically when rebooting

I have The following problem after installing mac osx lion on my Mac book: The computer shuts down automatically few seconds after i reboot The computer. Please help. I checked The disk utility but there are nô errors on The disk.

Hi
Have you solve your problem yet? Mine was the same - it's Dockables "fault"
Were you able to boot into Safe Mode, by pressing and holding Shift key at Start up, I think you need to press and hold a while, till you see a progress bar below the Apple logo.
Then you can quickly go and delete all the Dockables.
If you found another way to boot up, also delete Dockables immediately.
Cheers

Satellite M100 shuts down automatically after about 10min

Hey there guys :)
My Toshiba Laptop has been powering off abrubptly and on it's own lately.
When I turn my Laptop on, everything appears fine, battery if fully charged, AC adapter plugged in etc. However, after about 10 minutes of use it will just turn off and make a little 'zoip' noise or similar. Turning the laptop back on right after works, but I find that it will only stay on for about 4 minutes before doing the same. Turning it back on again reduces the time it stays on, sometimes not even going past the boot sequence.
However, if I leave it alone for a couple of hours and come back to it, it will stay on for about 10 minutes again, before going thru the same process.
I have a waranty, but I'm hesitant in taking my laptop in because I don't want to lose my files.
So I am hoping someone here has a fix for my problem :)
Thank you,
Osman

Hi
Sorry to said it but in my opinion its a hardware problem. This strange notebook behavior seems to be a simply overheating!
The notebook supports an overheating protection to prevent the hardware from the damage.
If the temperature increases to the higher level the notebook shuts down automatically. This is a fact and nothing unusual in such case.
Mostly the fan cleaning helps but sometimes the notebook must be opened for professional cleaning. But note: I dont recommend opening or removing any cases! You would lose the warranty!!!
Maybe a simple vacuuming would make the job.
Anyway, you said you will not lose the data on your HDD. Well, I wonder why you dont create an data backup You can also remove the HDD and connect it via external USB controller to the second PC and could save the files on the other HDD.
After this procedure you should put the HDD again into the notebook and try to reinstall the OS.
If it does not help I would recommend taking the warranty.

Macbook shuts down unexpectedly after an hour of use

I've had my MacBook since 2006, and I've had some minor problems now and then.
But since few days ago, my mac shuts down unexpectedly after I use it for about an hour.
at first I thought that maybe it's the fan, cause I've never cleaned the fan since the day I've bought it and my mac gets pretty hot after a while. but it used to work just fine when it got even hotter.
now I'm guessing maybe it's the battery? I've also never replaced the battery to a new one, cause I've almost always used power adapter instead of using battery alone. but I think I've heard it somewhere that the battery still dies even when you only use power adapter. is this true?
I usually just turn mac right back on when it shuts down, and it goes well for about 30 mins and then it shuts down again.
could anyone please be kind enough to tell me if it is the battery that's causing this such a frustrating problem? I don't know if this would help figure out the problem, but this is what battery info says,
Battery Information:
Battery Installed: Yes
First low level warning: No
Full Charge Capacity (mAh): 3674
Remaining Capacity (mAh): 3648
Amperage (mA): 0
Voltage (mV): 12443
Cycle Count: 105

Thank you so much for answering! I've actually read your answer to other similar forum, and have just installed iStatPro. it says that my fan is "exhaust" and at 0rpm. do i HAVE to replace the fan to a new one? can I just open up my mac and clean out the fan? if so, would you recommend this instead of buying a new fan? one last thing, if I buy a new fan, is it easy for me to replace it by myself? again, thank you so much for your answer.

MacBook Shuts Down Unexpectedly After Inserting DVD

I was about to watch my new TRANSFORMERS movie on DVD and after about 3 minutes of watching, my MacBook just shuts down immediately, so i tried the second time. This time, i was plugging in my ipod to recharge while the movie was paused. Once i got back and started to play my movie, the whole screen turned black (but the movie was still playing), and it shuts down again. Can anyone please tell me why??

I have JUST started experiencing the same problems where I'll insert a DVD and the computer may or +may not+ shut down unexpectedly in the middle of playing. When I try to restart with the dvd still in the laptop, it may also shut down again before I can successfully log in. This has also happened with several different DVDs over the last 4 days, so I don't think it's tied to the DVD itself...
I also have the computer on, plugged in, with the battery taken out, and with an external harddrive and mouse plugged in. Are the peripherals making it worse?
I bought my macbook in the US with a 3 year applecare plan and am now living in Beijing, China. I would like to be able to get this issue fixed, but don't know where to begin with calling a place in China. What is the protocol?

MacBook shuts down abruptly after some time, then has problems starting

I have 13" MacBook that I'm having some problems with. I have OS X and Windows XP in a dual boot configuration, and the problem happens in either OS. I can only use the computer for anything from 3 to 30 minutes before it suddenly shuts down.
When this first happens, I get trouble restarting it. It often just comes as far as intialising the DVD-ROM (you hear the sound), then it shuts off again. It can take up to ten starts before it powers up again. And then it's just a matter of time before the whole thing starts again. This happens regardless if I have the charger connected or not, or if I use just the charger and remove the battery.
At first it was thought that the battery was faulty, and I received a new one last spring. However, the problem quickly returned, and I haven't bother to do anything more about it before now. Suffice to say, I miss using my shiny MacBook, and I hope that someone can point me out in the right direction. As the computer is 2 years this may, I doubt I can get it repaired for free on the warranty(?).
Long post, but I hope I've explained the problem thourough enough. I believe I did the SMC reset and software update last summer, though I'm not sure which revision I'm on. If there's any more information I can provide, please let me know. It just takes some time to get the computer to stay on long enough to check stuff

Macbook shuts down right after update.

IMG_5528.jpeg
I downloaded the last update. When the Mac shut down and restarted to install the update.. The computer shuts down. Not sure what is going on. Hope someone can help
I attempted to add picture

Hi DBolick5,
Thanks for visiting Apple Support Communities.
If your Mac is not starting up after installing an update, first try booting into Safe Mode:
Mac OS X: What is Safe Boot, Safe Mode?
http://support.apple.com/kb/ht1564
Starting up in Safe Mode
To start up into Safe Mode (to Safe Boot), follow these steps.
Be sure your Mac is shut down.
Press the power button.
Immediately after you hear the startup tone, hold the Shift key.
The Shift key should be held as soon as possible after the startup tone, but not before the tone.
Release the Shift key when you see the gray Apple logo and the progress indicator (looks like a spinning gear).
After the logo appears, you should see a progress bar during startup. This indicates that your computer is performing a directory check as part of Safe Mode.
To leave Safe Mode, restart your computer without holding any keys during startup.
Regards,
Jeremy

N73 got shuts down automatically after some time

hi,
my n73 music edition gets shut down after some time autmatically please can anybody tell me the reason.

The reason is that nokia phones have many bugs and problems.
A common cause of this problem is 3G. If the phone is in a weak 3G area the loss of 3G signal can cause the phone to reboot. It's an old problem thats been affecting nokia's for years. Disabling 3G can stop the random shutdowns.
It may also be worth updating the phones firmware but this is a fairly risky procedure that can cause more problems than it solves.

Nano shuts down music after 30 seconds of play

I just got a 6th gen Nano. When I play music, it shuts off after a minute or so and the screen goes dark. If I hit the sleep button, it will display the song in paused mode. I've tried turning it off and holding down the sleep button for 10 seconds or so to turn it on and resetting the Nano. Neither works. Any suggestions?

Update: I found the problem in similar posts. Once I inserted the headphones completely in (no metal showing), the problem was resolved.

Equium A60 shuts down automatically after 10min

My laptop TOSHIBA Equium A60, after 10 min of work it logs off because it seems to become very hot although the fan is working?
How can I fix this problem

Hi I had the exact same problem
It was definitely overheating, unfortunately whoever designed the heat sink radiator didn't think about dust build-up!
I've owned mine for about a year and a half and recently (last 5-6 months) I noticed the fan running at full speed all the time, then during summer it overheated often, now that the weather is cooler I cant blame the sun!
So I went down the road brought a jewelers screwdriver set for next to nothing and started dis-assembling the laptop.
I first found some instructions off the net (print them out!), the trickiest part is to remember to get the three screws under the CD drive!.
Once I had it apart and removed the heat sink and fan it was immediately apparent what the problem was, the heat sink resembled a shag pile carpet!!!
I went down the road again and got a can of compressed air, blew the dust away, put it back together and hey presto, its hardly even warm!
Any fool can fix this problem, don't waste your money giving it to a technician who will charge you 70 per hour to fix it for you.

My iPad is shutting down apps after 30 seconds--any thoughts

I have restored completely twice and have only a few apps but it keeps happening

Try a System Reset:
Hold down the on/off switch and the Home button simultaneously until you see the Apple logo. Ignore the "Slide to power off" text if it appears.
A System Reset does not remove any apps, music, movies, etc. nor does it cause any settings to revert back to default.
Also, you might wish to download the iPad-2 User Guide. Pay special attention to page 162. Note that this Guide also applies to the iPad-1 with IOS 4.3 except for those functions that are not supported by the hardware.
http://support.apple.com/manuals/#ipad
Finally, the User Guide can be downloaded at no charge via iBooks and a less comprehensive version of the Guide is included as a Safari bookmark.
