MacBook is turns off during start up?

My MacBook Pro was running sluggishly and thinking a lot. There was plenty if storage space on it so not the problem.
I validated the disk and was then told to repair disc. After running this utility it says that it can't repair it and to backup and restore but now, on restarting the laptop it doesn't get past start up mode - the apple comes up and a gear turns underneath with a bar that fills to just about half way and then the laptop turns itself off!??
Any help greatly received!

If a safe boot does not help, I would suggest installing a new HDD and installing the OS and then see if you can access your old HDD via USB.

If you provide the EXACT model MBP you have and OS, more details may be forthcoming.

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.

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.

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.
Ciao.

MacBook keeps turning off on start up

My problems started when I kept getting this Hal.dll error msg on starting up my MacBook pro, which I understand is a windows file since I at one time needed windows XP on my MacBook to run a certain program.
When I realized I no longer needed Windows, I started (foolishly?) deleting any and all windows files I saw in my applications folder. I Now realize that probably wasnt a good idea. Ever since doing that, i'd get the above error message when I turned my comp on.
I finally got past this by restarting in safe mode. This worked ONCE, when my ext drive wasn't handy.
When I tried restarting again in safe mode later at home, the computer now keeps turning itself off !!!
Now I get the apple icon, the spinning wheel, the status bar slowly filling, and then it all disappears and the screen goes black and the computer turns off.
I have tried numerous times with power + shift (safe), power + option (which shows me the mac hd volume, but when I select it will still turn off), power + option+D, and power + shift +s > fsck -fy > reboot and after all of these attempts the computer still just turns off.
At this pt I just want to get that desktop back one more time to make sure I have the files I want on my ext drive and move on.
Anyone out there have any ideas or advice on how to could get past the computer always turning off on me on start up?

This sounds like the same thing that has been happening to both my Macbook and Macbook Pro. Some others sound like they have similar problems. This is what I posted in the Macbook Pro area regarding the same symptoms. This is discouraging. These computers are expensive and they should have the bugs worked out better than this.

I wonder if I have similar problems. I have both a Macbook Pro 15" and a Macbook 13"
1st my macbook started shutting itself off unexpectedly. It got more and more frequent. I have done several fixes including: archive and install, sending it in to have a logic board replaced, downloading an updated disc utility repair, and sending it in to have a power component replaced. Now I will be sending it in for a third time and I think they will replace the Macbook machine if this repair doesn't work.
Now my Macbook Pro is doing the same thing. I have had it for about 6 months and it was running fine until now. I ran the exact same software on my 12 G-4 powerbook without any problems. One of the computer people at work said it sounds like a power problem. It happens whether it is running AC or on battery power and doesnt seem to matter what I am doing.
I am waiting for the macbook to be fixed before I address the Macbook Pro because I dont want to have both of my computers in the shop at the same time.
Any suggestions? This seems totally unacceptable for two new expensive computers.

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 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:

Reinstalling Lion/Mountain Lion Without Erasing the Drive
Boot to the Recovery HD: Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
Repair the Hard Drive and Permissions: Upon startup select Disk Utility from the main menu. Repair the Hard Drive and Permissions as follows.
When the recovery menu appears select Disk Utility. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the main menu.
Reinstall Lion/Mountain Lion: Select Reinstall Lion/Mountain Lion and click on the Continue button.
Note: You will need an active Internet connection. I suggest using Ethernet if possible because it is three times faster than wireless.
If this does not work, then you will have to erase and reinstall Mountain Lion:
Install or Reinstall Lion/Mountain Lion from Scratch
Be sure you backup your files to an external drive or second internal drive because the following procedure will remove everything from the hard drive.
Boot to the Recovery HD:
Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
Erase the hard drive:
1. Select Disk Utility from the main menu and click on the Continue button.
2. After DU loads select your startup volume (usually Macintosh HD) from the
      left side list. Click on the Erase tab in the DU main window.
3. Set the format type to Mac OS Extended (Journaled.) Optionally, click on
        the Security button and set the Zero Data option to one-pass. Click on
      the Erase button and wait until the process has completed.
4. Quit DU and return to the main menu.
Reinstall Lion: Select Reinstall Lion/Mountain Lion and click on the Install button.
Note: You will need an active Internet connection. I suggest using Ethernet if possible
            because it is three times faster than wireless.

Do you have backups of all the data on the startup drive? If not, do nothing else until you've backed up that data, if you still can.

[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.

Macbook air turned off without warning?

Hi! Last night my macbook air turned off without warning and wouldn't turn back on until I tried again this morning. A few weeks ago I had my battery and logic board replaced and since then it the screen has gone blue for a few seconds and then back to normal a few times, (in case this is related at all). Is there something I should do to make sure this doesn't happen again.

As you say it is just been repaired I would take it back to the place that repaired it and ask them to look at it.

How to turn off the "start-up vibrating"?

I've just received my 6500slide.very nice handset.
now my problem with it is like this you know every time the red button is long-pressed,either to switch on or off the handset,it will vibrate for about 0.5second together with the start-up tone. now i turned off the "start-up tone" in "settings->phone",and the music doesn't play now when switching on and off,but still it vibrates~anybody knows how to turn it off too?
also i'd like to know if there is any way to set the brightness of the screen,or to set how long the screen and keys remain lighting after slided close.it's said to be automatically set,but i feel them a little too much bright~also not so friedly to the battery.
btw,i have to say that 6500slide's profile is a mess for me.~it seems that you can change the profile sets everywhere in the phone,but none of the changes works

Simply turn off or turn down your volume before you shutdown the computer and the next time you boot, at will be gone or at least a pleasant noise instead of a vociferious one.
You can also press the mute key combo just after you press the power button at startup.
