MacBook Pro turns off during boot?

This is kind of a long story.
I have a 13-inch, Mid-2010 MacBook Pro running OS X Mavericks. I was using it near a bathtub, when a moderate amount of water spilled onto the keyboard. I immediately dabbed out most of it, and put it upside down for some time. It was running then, with all the keys and trackpad working fine. t turned it off, and tired turning it on after half an hour. Nothing. I decided to keep it switched off for 7 days, during which I would open the lid every now and then to find vapor on the screen from the keyboard which I would wipe and close again. I turned it on when there was no vapor spotted for 3 days. I plugged it in after 7 days, to see that the battery status indicator was erratic. It turned on with a sound from the SuperDrive (the usual click). There was no startup chime. A few minutes later, it turned off. I decided to reset the PRAM and SMC, and I realized that I can get to my account window successfully (and type a 22 letter password) as long as I keep any key pressed throughout bootup (option, command key, etc). I have tried many times, but it just turns off with a "nik" sound. I haven't backed up, and I have about 270 GB of important data stored that I CANNOT lose.
If it helps, it's 250GB drive crashed in December but it was replaced with a 500 GB and has been running smooth until this.
Please help me! Any advice at all is extremely appreciated. Thank you!

Take the HDD out of the MBP and install it in an enclosure. Connect it to another Mac and see if you have access to the HDD. If so, copy what ever files that are important to you to another HDD.
Then you can take the MBP to an Apple store genius bar for a FREE evaluation. Prepare your self for unfavorable news.

Macbook Pro turns off during OS install

I have been given a 1st gen MacBook Pro to upgrade (clean install of Snow Leopard and a few apps). Specs are 2.16GHz with 2GB RAM and a (non-standard) 640GB drive. It is second hand so I don't know the history of it. After booting from SL DVD and starting the install (format drive first) the laptop turned off after a few minutes. Repeated process and same result and also tried a Leopard install DVD with the same result.
Any ideas? Never seen or heard of this ever happening to a machine short of having a power failure! The battery is fine and it will boot and run normally from an external drive.
Any help appriciated.
Cheers, Paul

Try a new internal drive.

My Macbook Pro turns off during start-up

About a week ago I started up my mackbook pro and it turned off after about 2 second after the start-up tone... this happened repeatedly. I found by holding down the "ECS" or "SHIFT" on start-up it boots up but then the "Are you sure you want to shut down this computer" window appears repeatedly, even when I click cancel. If I don't click canel within about 2 seconds, the computer turns off anyway.
I left it for a day or two and then tried starting it up again... it started up fine...??? I updated the OS from Lion to Mavericks as I needed the new version of Keynote.
Another day or two later... it was tuning itself off again on startup and once booted...???
Now I am here online trying to find some answers and have reset the PRAM... its still turning off. I left it for about 5 mins while typing this discussion in and it booted OK again and is still running.
Any suggestions?

danyog1,
if it works for you in Safe mode, then that suggests that something that runs at startup in normal mode could be the problem. Download and install EtreCheck, and please open your own discussion and include in your initial post there the output from a run of EtreCheck.

My Macbook Pro turns off suddenly with no reason

My Macbook Pro turns off suddenly with no reason. The battery it's ok, the temperature of the mac it's normal, but the pc turns off. What can i do ?

Xirver,
if you boot into Safe mode, does your MacBook Pro turn off suddenly then also?

Cleaned files and apps with "app cleaner" and now MacBook Air turns off during start up. What happens? What can I do? Please help

Cleaned files and apps with "app cleaner" and now MacBook Air turns off during start up. What happens? What can I do? Please help

The "app cleaner" managed to do bad things to the file system so that it is unable to boot any longer.
This is the primary reason I always recommend that any of those so called "cleanup" apps never be used. They do more harm then good.
Try a safe boot by holding down the shifgr key when you hear the boot chime. Maybe that can fix the damage.
Let us know what happens.

MacBook Pro turned off on its own and now won't turn back on.

MacBook Pro turned off on its own and now won't turn back on. Battery had 41% just before this happened and green indicator on power cord is showing, so it seems like it's charging. What should I do?

The led on the power adapter should be amber if it is charging. Green just indicates that it is supplying power to the MBP.
Try a SMC reset:

I wanted to calibrate the battery my new macbook pro turns off

You should perform this procedure when you first use your computer? is this true? new macbook pro on may 11 2010 what happed was today on may 22 2010 i wanted to calibrate the battery my new macbook pro turns off when it runs out of battery. 3 times Typically, when macs run out of battery, they go into sleep mode. However mine skips this completely and just turns off. WHY? does this mean the battery is bad?
Resetting the PRAM (http://docs.info.apple.com/article.html?path=Mac/10.6/en/26871.html) fixed the problem in my case. then i did the calibrate the battery again this time it went to sleep not shut down i did this 3 more times why?
the 3 forced shut downs without entering SafeSleep. with logs indicating improper shutdown, will that cause severe corruption to the os and do i have to reinstall the os now?2.66 ghz 2010

the 9 more 4 in 10.6.4 forced shut downs without entering SafeSleep. with logs indicating improper shutdown, will that cause severe corruption to the os and do i have to reinstall the os now?2.66 ghz 2010 but if it happens again you should try
i hate to do this reinstalling the OS, if this do not work also, then you should call apple, or take your MBP to an apple store. on june 24 2010 i am going to talk to spence about this. so what do i do now? this happed on june 16 2010 4 more times
without entering SafeSleep. only one time it worked on 10.6.4

This is a current sensor on the power bus. This seems consistent with your symptoms.

macbook pro turns off when i unpliug

You either need to plug in your charger and if that isn't working if your machine is less than a year old take it in to your nearst Apple Store and let them deal with it. Or if you are out of warrantee you will need to get a new battery for your Mac

[SOLVED] USB Harddrive via fstab turned off during Boot - Error

Hello^^
I'm trying to mount my external USB Drive.
I put the following line in fstab:
/dev/sdb1 /media/Musik ext4 noauto,user,default 0 1
I only want to start the Harddive occasionally.
The problem is, when the drive is completly turned off during boot I get the following error:
No such file or directory while trying to open /dev/sdb1
Possibly non existend device?
I thought that the noauto Option should prevent fstab from mounting the hdd???
regards

PS: Manual mounting works without any problems...

Let me give you a hand then. The following I have in my /etc/udev/rules.d/11-media-by-label-auto-mount.rules, and what it does is:
-- pick the name of a drive,
-- create a dedicated /media/mountpoint name (certainly, "mountpoint" is replaced by the name of your drive),
-- mount the drive on boot,
-- unmount the drive on shutdown and delete the /media/mountpoint.
KERNEL!="sd[a-z][0-9]", GOTO="media_by_label_auto_mount_end"
# Import FS infos
IMPORT{program}="/sbin/blkid -o udev -p %N"
# Get a label if present, otherwise specify one
ENV{ID_FS_LABEL}!="", ENV{dir_name}="%E{ID_FS_LABEL}"
ENV{ID_FS_LABEL}=="", ENV{dir_name}="usbhd-%k"
# Global mount options
ACTION=="add", ENV{mount_options}="relatime"
# Filesystem-specific mount options
ACTION=="add", ENV{ID_FS_TYPE}=="vfat|ntfs", ENV{mount_options}="$env{mount_options},utf8,gid=100,umask=002"
# Mount the device
ACTION=="add", RUN+="/bin/mkdir -p /media/%E{dir_name}", RUN+="/bin/mount -o $env{mount_options} /dev/%k /media/%E{dir_name}"
# Clean up after removal
ACTION=="remove", ENV{dir_name}!="", RUN+="/bin/umount -l /media/%E{dir_name}", RUN+="/bin/rmdir /media/%E{dir_name}"
# Exit
LABEL="media_by_label_auto_mount_end"
Plenty of handy examples you can find in /lib/udev/rules.d/ and modify them so they meet you needs. I hope it clarifies the matter a bit.

My MacBook Pro shuts off during startup

When startup the apple logo appears, a spinning gear, and a bar partily filled(10%)
The bar disappears then reappears and disappears when the bar disappears the MacBook Pro shut off
(Haven't updated macbook since bought in 2011)

Yimajatl,
boot your MacBook Pro from your grey Mac OS Install DVD. When the desktop appears, select Utilities from the menu bar, and then select Disk Utility. On the left-hand side of the Disk Utility window, select your internal disk’s boot partition (typically called “Macintosh HD”). On the right-hand side, press the Verify Disk button if it’s not greyed out; if it is greyed out, or if it reports that errors were found, press the Repair Disk button. Once the verification/repair is completed, exit Disk Utility and select Restart from the Apple menu to restart in normal mode. Are you able to reach your login screen now?

My late 2012 MacBook Pro turns off at start screen

I Just got the display replaced on my late 2012 MacBook Pro and when I turn it on, a white screen shows up with a grey apple logo and a loading bar underneath. When the bar fills up about an inch, a gear circle shows up for a few seconda and my computer shuts off. Could anyone help me with this please?

Hello TUTBUR,
I'm sorry to hear you are having issues with your MacBook Pro. If you are unable to boot past the grey Apple screen, you may find the information and troubleshooting steps outlined in the following article helpful:

MacBook Pro Turns off Randomly Only when logged in OSX 10.8.2

Hi,
I have a 2010 Macbook pro with Mountain Lion 10.8.2. For a couple of weeks now, when its not plugged in to AC it turns off randomly, not at any specific battery%.
Things I have tried already that were not helpful:
- System profiler battery: 374 cycles, Battery Status: Normal
- SMC reset
- Clean install of Mountain Lion without any Migraion of old System files (wanted to do this anyways before the problem arose)
- Its does not seem to be a heating issue, has happened at low temperatures
What I have noticed is that if I either run the diagnostics at startup or enter to recovery mode, I can run the battery all the way to 0% (lasts a while) and this random swtiching off doesn't occur. It only happens when I am logged in to OSX. This makes me think its not a battery issue either.
Any help would be great.
Thanks!

Please read this whole message before doing anything.
This procedure is a diagnostic test. It’s unlikely to solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
The purpose of the test is to determine whether the problem is caused by third-party software that loads automatically at startup or login.
Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards. Boot in safe mode* and log in to the account with the problem. The instructions provided by Apple are as follows:
Shut down your computer, wait 30 seconds, and then hold down the shift key while pressing the power button.
When you see the gray Apple logo, release the shift key.
If you are prompted to log in, type your password, and then hold down the shift key again as you click Log in.
*Note: If FileVault is enabled under OS X 10.7 or later, or if a firmware password is set, or if the boot volume is a software RAID, you can’t boot in safe mode. Safe mode is much slower to boot and run than normal, and some things won’t work at all, including wireless networking on certain Macs. The next normal boot may also be somewhat slow.
The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin. Test while in safe mode. Same problem? After testing, reboot as usual (i.e., not in safe mode) and verify that you still have the problem. Post the results of the test.

Macbook Pro shuts down during boot

Hi there,
Few days ago I spilled some beer on my 2 weeks old Macbook Pro... I immediately cleaned it, removed the battery and charger and left it to dry for 1.5 day.
After the drying period I tried to power up the machine, it did work but unfortutanely shut itself during the boot (the spinning wheel) and power button didn't respond again until I removed and re-connect my battery. Tried everything such as Nvram/Pram and SMC reset, single user thing, verbose mode, changing ram dimms but got nothing. It did eventually boot with hardware test but again got nothing as the test indicated that there weren't any problems.
It always shuts itself after "Checking catalog file" in the verbose mode.
(The machine shuts itself even when I try to boot it with os x installation disc so the only thing that I can reach is the hardware test.)
(To tell the truth I don't know if I succeeded creating a bootable installation disc as I did it under windows.. I'm hoping that I failed and that it can actually boot from dvd drive)
Did I just screwed my logic-board, if so how can I run all the tests.. Any suggestions?

Actually the computer is 2 weeks old, I spilled the beer 2 days ago.
Immediately disconnect all peripherals, power cord & remove the battery. Turn the computer over with the lid partly open and the hinge facing upward to let the liquid drain. Do not flop it over and lay it flat - you want to separate it from the moisture. Place paper or cloth towels under the machine to sop up the mess.
After the computer disgorges whatever you spilled on it, don't turn it on for 72 hours or longer. You want to computer to dry out completely before turning it on again.
Some users here swear by hairdryers. Blow drying the innards may bake whatever was in the liquid onto delicate computer components. Better to let the computer air dry.
Use plain tepid water to clean out the computer. If you spilled iced beverage more than likely this ice fried the hot motherboard.
Sugary, acidic or milky drinks will almost always cause problems later on as the residue starts slowly corroding the computer innards.
Swab down any sticky parts with distilled water or denatured alcohol.
If none of the above works, you will need to take the computer to a repair shop. Apple Care does not cover liquid or food damage. Believe me, they can tell. So the old "my computer stopped working" line is not going to work.
In order to not void your warranty any further, take it and let the staff clean it. It's worth it for a 2 week old computer. In the future, avoid eating and drinking while using your computer. Will avoid future heartache and expense.
