MacBook Pro starts but shuts down

My laptop was in sleep mode for about 4 days. I try starting up now and it will not complete the startup process. I see a white screen then the progress bar at bottom and then it just shuts off. How do I get the MacBook to fully start up again. It is only about 6 months old.

Hope when reading this will help with issue, further down this page Resolve startup issues and perform disk maintenance with Disk Utility and fsck - Apple Support

My computer starts but then immediately shuts down

Computer starts but quickly shuts down.

could be a broken cpu fan
if it's not spinning then the system would shutdown to avoid getting overheatet and die

Just done a fresh install of Snow Leopard with all updates,iMac 5.1 behaves strange, sometimes I start Google Chrome and look at youtube videos the computer freezes and shuts down immediately, I believe its related to overheating ?

Just done a replacement of the pata DVD drive (its new and is working ok), and a fresh clean install of Snow Leopard with all updates, iMac 5.1 behaves strange, sometimes I start Google Chrome and look at youtube videos the computer freezes and shuts down immediately,
I believe its related to overheating ?
iStat Pro shows GPU diode temp at 66 C, CPU at 48 C, Fan rpms is around 1000
Any ideas somebody ?
The hard disk has been previously checked with state of the art techniques that have confirmed that the hard disk drive is in perfect condition.

1.5-3 minute boot up as opposed to 15-20 seconds
And
why it takes a long time to load a lot of things.
I have restored this
from a time machine partition.
TimeMachine is only a backup and restore, it won't fix issues in software and according to your information, doesn't even optimize the restore for best performance on boot hard drives.
What you need to do to regain your speed is to understand how your machine works
Why is my computer slow?
Fix any and all issues in software following this list of fixes
..Step by Step to fix your Mac
Then follow this defrag method I've outlined
How to safely defrag a Mac's hard drive
Most commonly used backup methods
There shouldn't be need to reinstall OS X fresh unless your having file structure issues which if they are should appear when in the Steps, which then a zero erase and install will cure as well as any bad sector issues, the defrag step wouldn't be necessarry on a freshly installed system obviously as the files are written all together, not in portions all over the drive.
Hope this assists.

When I start iPhoto it opens up but shut down after a few seconds. Any advice please?

Try this: launch iPhoto with the Option key held down and create a new, test library. Import some photos and test to see if the same problem persists. If that does the same or you can't create a new library try the following:
1 - delete the iPhoto preference file, com.apple.iPhoto.plist, that resides in your
User/Home/Library/ Preferences folder.
2 - delete iPhoto's cache file, Cache.db, that is located in your
User/Home/Library/Caches/com.apple.iPhoto folder (Snow Leopard and Earlier).
or with Lion and Mt. Lion from the User/Library/Containers/com.apple.iPhoto/
Data/Library/Caches/com.apple.iPhoto folder
3 - launch iPhoto and try again.
NOTE 1: If you're moved your library from its default location in your Home/Pictures folder you will have to point iPhoto to its new location when you next open iPhoto by holding down the Option key when launching iPhoto. You'll also have to reset the iPhoto's various preferences.
NOTE 2: In Lion and Mountain Lion the Library folder is now invisible. To make it permanently visible enter the following in the Terminal application window: chflags nohidden ~/Library and hit the Enter button - 10.7: Un-hide the User Library folder.

I am so frustrated I could spit.. I have been experiencing issues for 1 week now and am unable to use my iphone. It started by shutting down every time I'd try to use it and now it won't turn on. When I plugged it in the charger apple flashes .

i have been unable to use my iphone for going on a week. It started by shutting down when ever I'd try to use it. Now it has just a dead black screen. If i plug it in it doesn't charge And the flashing apple continues every 2seconds never charging or turning on. I'm frustrated because I can't even get in to troubleshoot. I bought an iphone cuz I thought it was the best phone at the time. My contract isn't up til Aug. and I'm stuck with a bill and no phone. I do not own a computer but I have an ipad4 which I love. HELP!

Make an appointment at the genius bar are your nearest Apple store. At this point there is nothing you can do without a computer, so if you don't have one and don't know anyone who has one that you can use the Apple store is a good fallback.

Solved Vista Home Premium Start up / shut down loop

Ta Da The C:\windows\winsxs ETC. that was my solution found it on this site and other sites and decided to try it:
It was actually the 3rd choice of solutions on that particular page and I could not complete the solution as directed because the files I was supposed to delete were not there, funnily enough that is why I chose that solution as I really did not believe it was an update error but may provide me with a "Look Inside" . So I followed along and it would not let me delete the file as instructed but it let me rename it I did rename 1 file and rebooted. Everything proceeded as normal but it actually finished loading the NVidia driver for onboard graphics ( which was where it was crashing ) and that was it.
I still dont know for sure why it would not load the driver and I never did get any blue screens or failed update messages or error codes. On the upside I now have a working repair disk that I didnt have before, and created a backup that I didnt do before
I have an HP Pavilion m 7580n ( Media Center) that is locked in a start up shut down loop.
It starts normally and runs up normally until the desktop flashes on the screen for about 3 seconds. At this point It is still loading things like the Internet connection , Icon indicates connected, nvidia control panel icon. It never gets any further than that.....?
if I am fast enough to dbl click an icon it will load whatever the icon represents but will immediately flash to the "Shutting down" screen. It then shuts down and auto starts the loop again.
I have also tried ctrl / alt / del and I get there but it crashes instantly.
The machine is now running Vista Home Premium. Upgraded from XP by an online download so I have no OEM disk.
I dont know if it is 32 or 64 bit I would guess 32 as it was an XP upgrade
What I have tried so far
I have ruled out ANY Hardware problems by swapping hard drives and loading a different OS. Win 7 on it and everything works fine for hours. Benchmarks, stress tests, temp tests, games, mem tests
I have made a vista repair disk and tried all of the "Non Destructive" options available.
I have tried every safe mode option.
I have hooked the problem hard drive to another computer and accessed it that way, and ran virus scanners
and clean and repair programs. No Bad sectors, clusters, nothing bad
I have removed all "Junk" and files I can replace
I have striped all unnecessary hardware. swapped RAM, Vid Cards ETC.
I have tried all of the above both connected and not connected to the Internet and everything many times and many differant combinations.
Nothing has made any difference at all
A little history of the machine.
It was bought second hand with the Vista Installed and came with a paper sticker with a hologram
and a Key That was apparently mailed after the online update ?
It was activated and displayed windows genuine logo in System Folder
It received updates automatically and by request no problems.
I mention this only because I cannot be absolute certain it is a legal copy and was wondering if this is some sort of disabling of pirated software or an expired demo?
It was used in a cottage where it could possibly of had a power failure during an auto update. I mention this as some update problems resemble my problem. I have shied away from trying those fixes as they involve elevated commands and such and my knowledge in that area is very limited. and I dont have any of the stages loading screens
It would be easy for me to format and reload an OS But the files I want are protected and I cant access them from another computer.
I havent Listed any Hardware as I am satisfied it is not a hardware issue However it is the AMD X 2 64 version
Any Non hardware related suggestions would be appreciated as I am certain this hardware all works
I get no BSOD's no errors.
Thanks for reading my lament

Do this, and while it is in the open re-examine your cpu pins w/ a bight light and hd zoom or a magnifying glass.
Thanks, xmad, I'll look at th CPU again tomorrow/next day under the glass when I take the board out. I already checked them under magnification and was leaning toward a funky board, but it never hurts to re-check. Eyesight is not what it used to be, for sure (I miss DOS, if that's a clue...). Don't want to flash the BIOS if not necessary, since it runs Windows fine and everything works except that RAM.
Bernhard, I don't have CPU-Z installed on that machine and don't want to install anything else until it's working normally. I'd never seen Click-Bios before and just need to get over my initial suspicion of something new! Also learn my way around it before I change anything. I'd never encountered a board reporting a bios different than printed on it. I've never messed with manual memory settings or done more overclocking than just a little exploratory and suprisingly successful nudge - if you could point me toward a good basic explaination of all those settings, I could learn from there.
Appreciate your input very much.
Have learned a lot just reading the threads here for the last few days. This is the best forum I've ever encountered. I'll report back - some suggestions in other posts resembling my problem ended with no resolution, and that's a shame because one doesn't know if it worked or not.

MacBook is starting to shut down after 5 minutes.

My MacBook has just started to shut down after 5-10 minutes. The computer still holds a charge, and the battery Percentage says that it's full, so I dont know what's going on.

If it's under AppleCare take it in immediately.
It is possible that a fan might not be working, and causing it to overheat & shutdown as a safety measure.
The other reason could be RAM.
But that's just my guess.

Computer just randomly shuts down, is sluggish

Hi all,
Been having a problem with my HP Pavillion 774e (runs Windows XP) for the past month or so now. . .it just shuts down at the most random times. Typically I will start the machine, get going on the internet, and then foom. . .it just shuts off and restarts itself. There are no error messages when this happens. It also seems very sluggish when I start it; it doesn't have the typical whir that it usually has; it's just slower and seems to catch and click a lot more than usual. Sometimes when it restarts, it seems like it's trying to catch, like an engine that you are trying to start with a key, clicking and buzzing over and over.
I've tried a number of things to try to get it to not do this. I've opened up the computer, and cleaned it out thoroughly, I've run a malware scan, virus scan, run my copy of AVG PC Tuneup and cleaned things up, so I'm fairly certain it's not a virus/malware. I've also set the computer to not shut down on system failure in the control panel, and it doesn't help. I just can't figure it out. I've looked on many different forums for advice on what to do and I've seen advice about replacing motherboards, the power supply, etc.
I've also thought about doing a system restore (it seems to have begun when I had a windows update not install properly), but I'm concerned because if I go back that far, it would be before I ran the AVG PC Tuneup and downloaded a newer version of AVG 2012 (not sure if that would affect things, but it's why I'm concerned). I also worry because the thing doesn't stay on long enough to do anything; I just started it again and it shuts down in about two minutes. Safe mode also doesn't seem to help; it shuts down in there too.
Any advice on what to do with this machine? I don't want to junk it; it worked OK until just recently. But now, it's completely unreliable. By the way, I'm not an online gamer at all; I just want to use this thing for simple wordprocessing, powerpoints, and internet surfing.

seems like your power supply has started to show signs of it failing. Seeing that your computer is an older hp computer, its about time for something to show signs of getting wore out.

P7-1597c Commences Starting then Shuts Down

OK this may take a bit; I will start computer with built in graphics running, it will work for a couple of cold starts then try to start and shut down. I will put in my graphics card GE640, the computer will start and work fine I can restart but if I do a cold start it will try to start and shut down; so I will revert back to built in graphics; then install GE630 Graphics Card, computer will start, run fine and same symptom on cold start and the cycle continues. The following are some important additions I have made;
Added SATA Hard Drive
Added 750W Power Supply
Added 8GB Ram (I have 64 bit system)
Using HP 27" Backlit LED Monitor & ACER 24" Monitor
Anyone have any ideas?

My computer won't shut down, it just restarts

my computer won't shut down, if I try to shut it down it just restarts.
If I hold the power button down on the computer face for 10 seconds it shuts down but will not restart after (the button remains unilluminated) I have to unplug it them plug it back in affterwards to start it again.
I've tried disk utility, Nortons, even restarting with command+S then typeing fsck- fy (return) as I read on one of your previous forms. but nothing seems to work, any help would be appreciated!
thank peter

First welcome to the discussions.
The first thing I would do is Repair Permissions.
http://discussions.apple.com/thread.jspa?messageID=607640&#607640
After reading all the reports on Norton and disruptive behavior it causes in OSX I would recommend UnInstalling it.
You might have an issue with something else causing your problem but reading through the link above and UnInstalling Norton is a good start to isolate your issue.
Cheers Don

As of late, my COMPUTER has been shutting down Randomly.....

Ok here is what is happening. I am on the compuer, and all of a sudden the whole screen goes black and the computer sort of shuts down. but not completely. i can't see anything or do anything, but when i hold down the power buttton and push it, after man tries, it eventually shuts all the way down. and then it takes a couple more pushes to turn the computer BACK on. the fan comes on, and it restarts. i am using Tiger, its a 1.2ghz ibok g4. and i'm about to cry.

Hi, Brenda. You have found the G3 Dual USB iBook Forum, but don't cry. The iBook G4 Forum can be found here:

Maybe someone there can help you out.
Good luck!

Computer refuses to shut down/log off

I have a MacBook running the latest version of OS X and it's exhibiting some very peculiar behavior. As the title suggests, it refuses to shut off or allow users to log off, furthermore, some applications don't open or work properly. I ran a verify disk and permissions and they've come back with zero errors. What should be my next step in troubleshooting these issues?

Hello,
If your MacBook refuses to Shut Down, try this using the keyboard command for Force Quit. Command + Option + Esc. That will bring up the Force Quit window. If there any applications running, they will be listed there and your computer will not shut down until those processes stop.
As for applications not opening. Try locating and send their preference files to the Trash. I'll use iPhoto for an example. It's preference file looks like this:
com.apple.iphoto.plist It's located here: MacintoshHD/Users/YourName/Library/Preferences. In that Preferences folder are the .plist folders for the applications you use. Send the .plist files to the Trash. It's ok.. your MacBook will create new .plist files for you You will have to reset your preferences on these applications but considering they aren't opening anyway, this might help.
Also, if you haven't already done so get a good disk utility that you can run to clean out caches and log files and repair permissions all in one fell swoop. I use Onyx, it's free and it's here: http://www.apple.com/downloads/macosx/systemdiskutilities/onyx.html Download and install Onyx. Run the Maintenance and Cleaning scripts and reboot.
Hopefully something I've suggested will help.
