Mbp keep shut down, if I release any button,

My mbp was an 2010 version,, in OSX, I buy it for work because trust of stable system, today it shut down automatically, and no weather what I try t reset mec or anythings else.... it keep shut down when boot up, if I hold any one key, it can boot up, but shut down after release the key about 10 sec...
By the way... many of the apple problem issue guide links are disable now.

Hi, thanks for help, I have try the disk repair, it finished repair at second time. But still have the problem. I also try to recover the *OS, but it show an unknown error and not allow me to continue recovery. I will try command R to partition the hard drive, then re install OSX,,, Hope it was only the hard drive goes wrong..... I already decide to replace with a ssd...
my mbp was a 2010 version, 2ghz duo core 2gb ram using it for 3d drawing and planing online store...

MBP keeps shutting down!

My macbookpro keeps shutting down by itself! It also makes a loud noise why I try to boot it up again.

Reset the SMC and PRAM following the procedure outlined here: http://docs.info.apple.com/article.html?artnum=303319 and http://docs.info.apple.com/article.html?artnum=2238
The loud noise is probably the startup chime, but if it's always loud, then your computer isn't saving the volume settings from the previous session.

HELP Ipod is stuck, will not shut down or respond to any button pushes

my ipod suddenly will not do anything, I was playing it & skipped to a track on it & it got stuck, the screen shows now playing but it is not doing anything, I cant get it to shut down play etc, or respond to any button click wheel pushes. I can feel it vibrating in my hand, I have plugged it in to itunes & nothing, it does not see it nor does windows. it has been working good so far, I just got it off ebay from someone 2-3 weeks ago. I have been using an inexpensive usb & AC charger with it, I did not see any reason to pay more for other branded usb & ac power adapters. I can feel it vibrating when I press the buttons but nothing happens.
I need some input soon, I dont want it to burn out.

what is causing it to crash? is there anyway to prevent it? I am using an inexpensive USB cable & AC power charger, can this cause problems? is there any difference between the cheap ones & the more expensive ones? I did not see any reason in paying 30.00 odd dollars for items that I can get for about 5.00 to to the same job, charge & sync my ipod. I have also just bought & been using an apple ipod radio remote to listen to FM radio, can this cause any problems?
Do skipping around to different songs & albums & sections on my ipod cause problems? is this bad for the hard drive?
when I 1st got the ipod, & hooked it up to itunes, I did not have to register it or anything, itunes just synced my library to it, in the info section on my ipod, it reads format; windows, & I am on a windows PC so it seemed ready to go.
do I need to do anything else to it now? it seems to be working now.

Mid 2012 retina MBP keeps shutting down

Hello, my mid 2012 retina macbookpro is being annoying, it keeps turning off at random times, I read some other people have been experiencing the same frustration
Do you happen to know what may be the problem and if there's a solution I should try before turning it in on warranty (I need it for work)...
Thanks,

My phone keeps shutting down approx every 5-10min for about a minute then it turns back on itself. I have updated the software so thats not the issue, any suggestions?

Do you have a case on the iPhone or have you damaged it in anyway? If you have a case, try testing without the case.
Also, try restoring the iPhone and testing it as a new device.
If that doesn't take care of it, get a Genius to take a look at it or setup service online.

Hello,
Have you blown the dust out lately?
One way to test is to Safe Boot from the HD, (holding Shift key down at bootup), run Disk Utility in Applications>Utilities, then highlight your drive, click on Repair Permissions, Test for problem in Safe Mode...
PS. Safe boot may stay on the gray radian for a long time, let it go, it's trying to repair the Hard Drive
Reboot, test again.
If it only does it in Regular Boot, then it could be some hardware problem like Video card, (Quartz is turned off in Safe Mode), or Airport, or some USB or Firewire device, or 3rd party add-on, Check System Preferences>Accounts>Login Items window to see if it or something relevant is listed.
Check the System Preferences>Other Row, for 3rd party Pref Panes.
Also look in these if they exist, some are invisible...

My macbook pro keeps shutting down when I try to use it , any ideas ?

I don’t know why this happens and with the information you have provided I doubt anyone can do so so with accuracy.
Please read these (they concern general trouble-shooting and how to pose questions on these fora):

Start by doing an SMC reset http://support.apple.com/kb/HT3964 and see if that resolves it.

Nokia Lumia 925 Windows phone keeps shutting down

     I have had a problem for the past 2 months, my Nokia Lumia 925 with Win 8.1 keeps shutting down spontaneously. (I did not have this problem before 8.1) This is my third phone in the last 2 months (warranty program keeps sending me replacements) and it shut down for the first time this morning. All 3 have developed the same problem, the phone will shut down spontaneously and the only way to start it up again is a soft reset (Volume down + Power for 15 seconds). I have had a total of 10-15 shutdowns between the 3 phones and this is a conservative estimate.
     I am thinking that this has to be a setting or an app that I use (and few others do) that is causing the shutdown since I have only seen a few other similar issues in the forums. Here are some of the basic facts about my situation and some of the actions I have taken:
              - I have wiped the phones repeatedly (3 phones wiped a total of 3 or 4 times not including the initial setup of the replacement phones, which is getting really old--really fast).
               - I have tried turning off NFC, but that obviously wasn't the issue because NFC was off this morning when it shut off.
                - I have tried trimming the screen protector/screen guard I installed as suggested in one of the other forums even though that seemed ridiculous (I think that was a different model phone too, but I gave it a shot)
I have not noticed any common occurrence such as
                           --when a certain app is running
                           --when it is on/off charger,
                           -- When the battery is full or low (it was 24% this morning).
               -I have 2 chargers, 3 if you include the car charger that I have never had to use due to great battery life.
               - I have called tech support several times, all AT&T can tell me is that this is not a known issue and I should wipe it again. Nokia says the same and that I should send it back to them for repairs. That seems fruitless to me because I have had 3 different phones, what are they going to repair that a new phone won't fix?
       It takes me 3 hours to reinstall and set up my apps, I am getting very frustrated. I really love the way this phone functions, the software is good, the screen is brilliant and very sensitive, the camera is great (although a bit slow), and the size and feel are perfect for me...I hope that someone here on the forums can help.
Thanks for your help in advance...

Hello, mariaadamsky.
We appreciate you reaching out to our community regarding your concern. You are using a Lumia 925 as well, correct? Did something happen to your phone that possibly caused such behavior? Did you try doing fixes on it?
Latest software released for Lumia phones is the Lumia Cyan. To confirm that you have it installed on your phone, go to Settings> extras+info. You can also try going to Settings> phone update> check for updates to check if there's an available update. Are your system apps also updated? While connected to WiFi, go to Store> ...> downloads to check for pending updates. Let's hope that the phone will not shut down while doing this process.
By the way, we can try other fixes that could help us identify the real cause of the issue. In case you wish to have it repaired in a Nokia Care Point, warranty claim may vary per region and Nokia does not have an international warranty. Also, creating a backup is a must to avoid data loss. Where did you buy the phone and where are you located right now? To know about the manufacturer's limited warranty, go here: http://nds1.nokia.com/files/support/global/phones/guides/Nokia_Manufacturers_Limited_Warranty_with_W....
We look forward to your reply.

MBP unexpectedly shuts down for no reason- help!

MBP unexpectedly shuts down for no reason.
My MBP has been working fine, until I updated to 10.5. Originally this problem started in Bootcamp running XP, but has now done this once in OS X, just a while ago. There seems to be no difference- even when the psu is plugged in. Just now when it did this again, I pressed the power key and the led on the front blinked really fast, then there was a tone- like it was doing a firmware update (but I did the firmware update months ago!).
I've done a power reset- taking out the battery and holding the power key down for 20 seconds, which seems to have helped, but then again this problem seems to be rather sporadic, and one can never tell when it is going to happen next.
Oh yes, there is a mechanical 'click' that sounds when it does it- like a relay click. Is there a relay power related IC on the motherboard?
Any clues anyone? (I'm sending this exact letter to Apple as well)
Tom

It's an interesting thread, but I seem to have the problem even when the cord is plugged in. I did have battery problems when I first got this MBP, but they seemed to settle down once I used the computer a bit more. FWIW, I have now got them mostly while using Bootcamp. BC beta 1.3 was really stable and good. It wasn't until I bought Leopard that this problem started. And again, it's only happened 3 or 4 times now.
I'll just have to keep saving. I'm sure Apple will wise up to this sooner or later. (Incidently, I haven't been able to send anything to Apple as I can't find their direct contact addie. Can someone 'remind' me? Thanks!

Mbp keep shut down, if I release any button,
