Macbook pro shuts down periodically intermittently

My macbook pro (~2010) shuts down intermittently. The whole thing just shuts off. I find that it seems to happen more often when Pages is running but I'm not entirely sure of the correlation.
Here is the error report that appears when it starts back up. Can anyone interpret it for me?

Mid-2010 15" MacBook Pros - the bad NVIDIA GPU
If you're having frequent kernel panics with your 15" mid-2010, or intermittent screen problems, the problem is, more than likely, the faulty NVIDIA GPU found in a number of those machines.
Here's just a sample of a kernel panic log that points to the faulty NVIDIA card:
Kernel Extensions in backtrace (with dependencies):

            dependency: com.apple.iokit.IOGraphicsFamily(2.2.1)@0x8301b000
Here's the "official" Apple take on the issue - but the very real kernel panics need not be preceded by 'Intermittent black screen or loss of video'... in fact, you might not experience any video problems at all. Although video problems can certainly be a portent of things to come…
So what can you do? Print out a copy of your kernel panic and a copy of the Knowledge Base article and take them, along with your machine, to your local Apple Store or an Apple Authorized Service Provider. The unfortunate thing is that many people have passed the “three years from date of purchase” now and Apple is not honoring the free logic board replacement for many users. Some dealers seem to be making some exceptions for those past the three year mark, but don’t count on it…
Good luck,
Clinton

Macbook pro shuts down intermittently

my macbook pro shuts down intermittently i do not know what the problem is ?

Dsannin,
if you boot your MacBook Pro in Safe mode, does it behave in the same way?

My girlfriends Macbook Pro shuts down at the Apple Logo....

My girlfriends Macbook Pro shuts down at the Apple Logo....
1)I start the computer
2)It loads to the apple logo
3)A progress bar shows and loads about 5% then it dissappears and a few seconds later the macbook pro shuts down.
Any solutions?
If not, is there any way for me to reinstall the os without losing any files such as(any of her pictures, music, etc)?

Hi S,
See if you can run Repair Disk: Boot frominstall disc (insert disc > restart > immediately hold down c key andkeep holding it until you see “Preparing Installation”) > at first screenselect the language and click Continue > click on the Utilities Menu in themenu bar > open Disk Utility > select your HD in the panel on the leftside> click Repair Disk at bottom of main window. Run this at least twice,and keep running it until it says “appears ok” twice in a row. If that doesn’thappen, you may need a stronger utility such as DiskWarrior or if the directoryis damaged beyond repair, you may need to reinstall the OS, or you may have a damagedHD (repair utilities can only repair the directory structure, not the HDitself). When this is finished, quit Disk Utility, quit the installer, andrestart. Once booted normally, go to Applications > Utilities > DiskUtility and run Repair Permissions.

Macbook Pro shutting down. Hardware error code 4MEM/62/40000000:0x7f537f90

Macbook Pro shutting down. Not the same action making it shutdown. Anywhere from being online to attaching a photo to an email to working in Word or Photoshop. Even after it's closed and not being used. I come back to it being shut off and saying it had to restart because of a problem. I ran the Hardware check and got the Hardware error code 4MEM/62/40000000:0x7f537f90.
I must say I am quite disappointed. I have used Mac for work but had a PC since day one, and I JUST got this Macbook Pro in Dec. I was delighted that Mac usually didn't have as many problems with viruses etc as PC. And now last couple days, constantly shutting itself down. The closest store to me is a few hrs away. I am in South Dakota, store is in Minnesota Any help would be appreciated.

Can you post a screen shot of About This Mac -> (More Info) -> System Report -> Memory and click on each DIMM and post the bottom right pane. You can also do the same without a screen shot using just text version using the following highlighted command in OSX Terminal. The output is also listed.

My 15" Macbook Pro, shuts down by it self (Random occurrence).

My 15" Macbook Pro, shuts down (randomly) by it self, some times it will not turn on, and some other times (very rarely) the fans go on “very loudly” the second I turn it on. But the computer, does not turn on at all, even with the battery fully charged and the fans runing full blast.
Some other times, it will not wake up. It will only turn on or wake up if connected to the power adapter, even if the battery is fully charged.
I have already reset (a couple times) de firmware, the smc and he pmu and the problem persists.
Al this goes on randomly and unpredictably. Some times it works just fine for 4 or 5 days and the suddenly something happens.
I also think that some times the computer runs extremely hot.
PLEASE HELP!!!!!!

15' MacBook Pro Mac OS X (10.4.8)

I have the same thing happening with a new macbook I bought my wife and I called apple today and after going back and forth between apple care and apple customer service they are shipping me out a new replacement macbook as it is less than 30 days since I bought it. I am waiting for their email with the Fed ex info so I can send this one back and then they will send out the new one.
If it is still in warranty I suggest you call Apple customer service and let them know how bad it is and insist on a new one!
This one also reboots at the slightest movement and it took me several tries to finally log in on it tonight to delete all the user accounts before I send it back!
Hopefully the replacement one is glitch free!

MacBook Pro shuts down when i close the lid

Hey,
My MacBook Pro shuts down when i close the lid.
It started to do this one or two times, but now it is every time.
I have the latest battery update, so this should not be the issue here..
Any sugestions??
I have started to suspect the it might be some faulty conecctions or somthing..

If it's unable to go into the proper sleep state for some reason then it will do that.
Run /Utilities/Console and click 'All Messages' top left then close the lid, wait a minute then open it again - if it's shut down then reboot and open Console again and check the latest log lines looking for 'sleepimage' - it should give you an indication of what happened/didn't. If you're not sure what it all means post _just those lines_ here.

Macbook Pro Shuts Down During or Soon After Start-Up

My macbook pro shuts down after booting up. Sometimes it makes it to the desktop, but sometimes just to the gray screen. Also, at desktop, it asks if I want to shut down. Is something pressing on the shutdown button? Any help on what to do?

Try resetting the SMC.

Power or other problems related to unexpected system sleep, shutdown, lights or fans call for an SMC reset. Read all the steps.
Before Resetting the SMC
Try each of the following steps in this order before you reset the SMC. Test the issue after completing each troubleshooting step to determine if the issue still occurs.
Press Command + Option + Escape to force quit any application that is not responding.
Put your Mac to sleep by choosing the Apple () menu from the upper-left menu bar and then choosing Sleep. Wake the computer after it has gone to sleep.
Restart your Mac by choosing the Apple () menu from the upper-left menu bar and then choosing Restart.
Shut down your Mac by choosing the Apple () menu from the upper-left menu bar and then choosing Shut Down.
Resetting the SMC on portables with a battery you should not remove on your own
Shut down the computer.
Plug in the MagSafe power adapter to a power source, connecting it to the Mac if it's not already connected.
On the built-in keyboard, press the (left side) Shift-Control-Option keys and the power button at the same time. The power adapter indicator light may cycle off / on once.

Welcome to Apple Discussions!
This is just a wild guess on my part, but I have read that when a hard drive is beginning to fail, sometimes the optical drive will also malfunction. You can check out the physical health of your hard drive with the following utility:
http://www.versiontracker.com/dyn/moreinfo/macosx/32454
You can download the demo and run it several times for free.
The instructions to restart your computer sounds like you might be experiencing a kernel panic. Here's a link to read about that:
http://www.thexlab.com/faqs/kernelpanics.html
It's also possible that the optical drive itself is going south. You could run the extended version of the Apple Hardware test to see if you get an error code that would indicate the optical drive.
Good luck!

My macbook pro shuts down OSX and all my programs when the lid is closed

Hi,
I am having a problem. My macbook pro shuts down OSX and all my programs when the lid is closed. I close the lid, and then I hear the shutdown music and then when I open it again it automatically restarts OSX and all my windows and programs are closed, any info gone.
This doesn't happen all the time. Just once a day or maybe twice a day. It seems like it happens basically when I have my computer just the way I want it, to keep an eye on things for the day.
I just recently switched to a mac and while somewhat savvy, I am not a programmer or techie, but it seems to me that when I shut the lid, it should do the same thing every time.
I have a intel core 2 duo 17 inch macbook pro with 2.33 processr and 2 gig ram, if that helps.
I am in alaska and there is no genius bar here and I am hoping to figure this out before I begin bugging our local independant mac store about this.
Thanks in advance,
Lylah

Ahhh, enlightenment!
That would make sense. What I usually do, after closing the lid, is to wait for the apple to turn off and then set it down on it's side leaning it against the side table. I will try to wait for it to indicate that it is fully asleep before I move it next time. Personally, I prefer my computer to NOT fall asleep at all, but I am told it is not an option. Apparently this function is hardware related accoring to my local mac shop. They tracked it down for me because I hated this feature when I first bought my computer and was trying some way around it.
The shutdown music I was refering to was that music the mac makes when shutting down, which doesnt usually occur when it goes to sleep, unless it is malfunctioning like this.
What does resetting the pmu do? (what is a pmu as well?)
Thank you very much.
Lylah
