MacBook Pro shuts down abruptly during startup

Every time i turn on my laptop it starts up in safe mode and stops the progress bar. Then, it goes away and the computer shuts down. What do i do?

If you are under warranty or have Apple Care, give them a call and get a case number. Otherwise, take the computer to an Apple store or an AASP. Whichever is more convenient for you.

Macbook Air Shuts Down Unexpectedly During Startup following 10.5.7 Update

Downloaded 10.5.7 through the software update, installed, restarted. The grey screen appears, and after about 20 seconds the computer just turns off. Tried zapping PRAM, no avail. Any ideas on where to go from here? I don't have a ComboDrive/Superdrive for my MBA...

Some people have had more success by downloading the Combo update and reinstalling that way rather than through Software Update.

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.

MacBook Pro shutting down on bootup

My MacBook Pro, as of today, shuts down automatically during startup. I believe this to be an issue caused by the limited amount of storage available on the internal harddrive. I've managed to boot from an older backup on my external harddrive, and while I can copy files from the internal to the external, I can't seem to delete any files from it in order to free up some space and bootup properly again. I receive the error "The item can't be moved to the trash because it can't be deleted." Is there any way I can delete files that are on my internal harddrive, while I'm booted from my external harddrive?

I do not currently have the means to back up the data on my internal harddrive as my only available external harddrive is the one I'm using to run the older backup from. My original question was is there any way I can delete files that are on my internal harddrive, while I'm booted from my external harddrive?
Do you know if this is possible or not?

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.

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.

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.

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!
