Macbook Pro 2012 wont boot

While i was using my Macbook all of a sudden it shutdown when i connected a usb to it. It was/is charged to 98/100%. The charger is shockproof and after the shutdown the light at the end of the charger is very faint. Any advice? I wanna avoid opening it but apple is not an option in my country.

  • Brand new MacBook Pro 2012 not booting install of Mountain Lion

    Hi,
    I have a brand new 15" MacBook Pro 2012 model (2.6Ghz, 8GB Ram) - works fine on OS X Lion. As I had just bought it I decided to upgrade it to Mountain Lion straight away, and here's where the problems start.
    After apparent install the machine re-boots, but upon re-boot I get what I have found to be called 'the grey screen of death' where the loading icon disappears and the apple logo appears and the screen dulls slightly. I have also noticed that through the install process I lose keyboard and trackpad funcionality and the 'spinning wheel of death' froze, even though the loading icon contined to countdown the minutes till install.
    I have read many threads online now about how to reboot and reinstall OS X Lion, I have done this succesfully. I managed to save the OS X Mountain Lion files to an external device and attempt to reboot that way - same problems!
    How on earth do I get OS X Mountain Lion working on this machine?
    From the threads I have read no one has answered this - they simply answer how to reboot into OS X Lion. Others have stated that they have been in to see Apple's "Genuis" bar and the "Genious's" cannot explain the problem and attempt to put it down to hard drive failures etc. Problem is, there seems to be a **** of a lot of people out there with the same issue - surely it's OS problems and not hardware if it's a brand new MacBook?
    Has anyone else experienced this? And does anyone else have a solution to my problem?
    For the record, I have updated my EFI and firmware as well as my operating system before attempting install.
    Cheers,
    Leigh

    As you've Mountain Lion, press Command and R keys on boot, open Disk Utility, erase the drive and reinstall Mountain Lion

  • Macbook pro a1150 wont boot past kernel, stuck on gray screen.

    got a macbook pro a1150 ati 1600 gpu.  last for characters in sn are vww.  will not boot past gray screen after the gray screen with the apple logo.  it has a fresh install of 10.6 on a new hard drive from a laptop of the same exact kind.  when in target mode and its Hard Drive used as a boot divice, it will boot.  no broken graphic on startup with the apple icon and the pin wheel spinning.  boots to safe mode just fine, will even do updates.  but will not boot from the NEW hard drive or the dvd rom.  when i put the old hard drive in with 10.5 it wont boot past the blue screen and the same with the 10.5 install disc i baught.  reset pram, changed ram, removed wifi card and even tried disconnecting the dvd rom but still will not go to the login screen.  even disabled auto login (when it was in target mode).  do i reflow the gpu? is it a gpu problem?  one thing strange.... in safe mode, lines show up on the mouse icon and just that.  the rest of the screen shows everything fine, i've seen this before with the nvidia chipset but not with ati.  how do i fix it?

    to better explain... the macbook pro in question never get to the blue startup screen which happenes before the login menu.  not though dvd rom, hard drive, external dvd rom or external hard drive.  just stop there.  i hear the hard drive working / dvd spinning and the computer reading the disc but after a few min of just seeing the grey screen both would spin down.

  • Macbook pro (retina) wont boot - can't get to recovery

    I'm having a bizarre problem with my Macbook pro retina 15".
    I was using bootcamp/booted into windows and playing Star wars the old republic when the machine suddenly froze, then the display started going into lots of squares of multiple colours.
    When I try to boot in to OSX it freezes after the apple logo and the small cirle stops. If I try get to the recovery by pressing cmd + r the same thing happens. I've also tried using the internet recovery option, the same thing happens after it connects to my wifi etc.
    If I press alt during bootup to get to the different drives to boot from, the icons (i.e. OSX or bootcamp) are displayed but are slightly brown and look a bit distorted. If I select bootcamp and try to boot into windows the squares/distorted screen issue starts again.
    I have also tried booting from a mountain lion install usb i made - same probelm as above: freezes after apple logo.
    I've also tried resetting the PRAM/NVRAM or whatever its called.
    Does anyone have any ideas I can try as I can't call Apple care til Monday now?
    Thanks

    Nope. Your only option is to take it to an Apple Genius Bar as your system is FUBAR. More then likely a hardware problem from over heating.

  • Macbook pro 2011 wont boot

    Hi,
    I need a help regarding issues with my macbook pro. I am getting bluescreen on start up. Here is a link: https://www.youtube.com/watch?v=lzryrh5x-Rs
    I did new reinstall of mountain lion but it was working for about 10min, after I did first update, I did restart but it just stopped at grey screen.
    I went also to apple shop, they did tests and said that all HW tests are ok and it should be something software related.
    What could be causing this issues? Could be logic bord regarding all HW tests?
    Interesting thing is that when it is doing recovery it can be powered whole night with no problems.
    A also did pram reset but no luck.
    Tnx

    Run these steps first. I see you reinstalled. Run the other troubleshooting options, particularly in the second article.
    If you see a blue screen at startup - Support - Apple
    Mac OS X: Gray screen appears during startup - Support - Apple
    If it persists, run the Apple hardware test. It could be your logicboard ...specifically thinking your discrete GPU since this has been such a big issue for these models.
    Using Apple Hardware Test - Support - Apple
    Message was edited by: nbar Completely misread the OP. I see hardware diagnostics checked out. Can you boot into SAFE MODE without trouble?

  • Mu macbook pro 2012 wont start it goes into this i cant get anything help please

    my macbook pro is only on safe mode, was working fine then plugged in battery charger and it came up with a funny screen and voice asking what language i wanted i did disc repair but it said it didnt need it all i can get into is the help line PLEASE HELP

    Adam,
    if preserving your files is worth your effort, then copy them to an external drive; if not, then don’t. Once you’ve preserved whatever you care to, go back into Disk Utility from Recovery mode, select your internal disk from the left-hand side of the window (probably the first item in the list), and select the Erase tab on the right-hand side. In the Format dropdown, select “Mac OS X Extended (Journaled)”; in the Name textbox, enter the name for your reformatted volume (“Macintosh HD” is typical); and then press the Erase… button. Once the erasure is completed, exit Disk Utility, and then select Shut Down from the Apple menu. When you power it up, OS X Internet Recovery will download your MacBook Pro’s original version of OS X from Apple’s servers, and then reïnstall it. When it restarts after the installation, run Software Update to bring it up-to-date, and then copy your preserved files back to your internal disk.

  • My Macbook Pro 2011 wont boot properly. only when batter is disconnected. HELP

    hi all.
    i have recently bought a macbook pro, 2011 i5 4GB knowing it wasn't fully working, but i need some help.
    when i try and power it on, nothing happens at all (it did turn on once for about 10 seconds, then shut itself down.) i have since been playing around with it, fault finding, and i have found out that if i have the battery disconnected, and have it connected to the charger it works! (if holding CMD+D.) i have tried running the hardwear test, but when holding down the relivent keys on startup it just continues to load the OS X as normal. i do not have the start up discs either. im not entirely sure where to go from here, id love to know what could possibly be causing this fault. any help would be greatly appreciated. thanks in advance.

    Update - I've got it all powered up, updated etc. it only doesn't start now after a forced shutdown (holding off button) if I press shutdown, restart etc it works fine. Really want this sorted, any help would be greatly appreciated. I'm ripping my hair out! Thanks

  • Macbook pro 17" wont boot up

    Greetings,
    I left my macbook working on my desk , when i came back back the computer was in sleep mode, the computer woke up but the screen did not turn on, however i could hear the sounds of OS X when i clicked on the volume keys but no video. after holding the power button for 7 seconds the computer turned off. when i tried restarting the computer the sleep light would light up and remain solid, but it would not boot.
    Took the ram out and the sleep light blinks 3 times, but when i put the ram back again but it goes back to the solid sleep light with out doing nothing
    some steps i took
    -battery is fully charged and it charges the battery
    -unable to do a pram
    -took off battery and disconnected form wall and hold the Power button for 8 second
    i would also note that this machine had the logic board replaced due to the nvidia 8600gt recall.
    Thank you in advance
    -Illankid

    well i took my mac to an apple authorized service center, the tech told me that computer does not boot up and thus they are not able to perform the "nvidia test" which mean that the laptop does not fall under the recall. so im stuck on ordering a new logic board on my dime.ill update on my decision.i am missing it.

  • Macbook pro retina wont boot

    A week old laptop refuses to boot have tried everything availiable online still no luck!
    Are apple skiming on quality?

    Many thanks, will try and get it replaced if lucky as get back to London on the 13th of January as presently in Kenya. Was happy with my original bought last year which has worked flwlessly so picked another for my daughter, however having it die in less than ten days is a pain as gave it to her as a Christmas present.
    What is the procedure when you book a genius appointment?
    Are they supposed to get it working while you wait?
    If they cant manage this do they replace the same machine?
    Any advice is highly appreciated.
    Thanks in advance

  • MacBook Pro: Tiger wont boot past grey apple screen w/ spinning gear, HELP!

    Hey everybody,
    I have a 1.83 Ghz MBP with 512 mb of RAM (lame I know). The other day someone was using my computer to burn a CD on iTunes when all of my programs began failing. On instinct I rebooted my computer to solve the problem. Alas, now I cant boot past the grey apple screen, and the gear is spinning away. Saddest part of the story is that I had time set aside to back up my computer the day after this happened . Anyway what is the best thing to do from here? I haven't made any moves to fix it yet really, so what is the best thing that I can do to try and get my files back?
    Thank you,
    Sam A.

    Hi, I posted to you in yoour other thread.
    I very much doubt Disk Utility or fsck will fix an +Invalid Node Structure+ error. That's a pretty serious error and DU is just not robust enough of a utility to repair it.
    If Disk Utility can't fix it, you'll need a more robust utility for the repair. I would recommend DiskWarrior. It is the best at directory repairs. It rebuilds then actually replaces your old directory. I feel every Mac owner should have a copy. Make sure you get the disk so you can boot up on it to run repairs. You can also install it on another drive and run it from there to repair this one. DW works faster that way.
    I use DW once a month to try and catch errors in my system from getting too far out of hand.
    If you have a good backup, hopefully a clone of your system before you had issues, an Erase and Install will also rid you of this issue. But, beware! You will lose everything on the drive with this procedure. Let us know if you need help with that!
    Cheers! DALE
    p.s. If the +Invalid Node Structure+ is real bad, there's a risk even the mighty DiskWarrior will not be able to help. Normally it will come thru; it's only in the severe cases it won't be able to do it. If you don't have a backup, and need the data bad, it's worth the try!

  • My macbook pro currently wont boot, when i turn it on it leads me to internet recovery and after that to the utilities pannel, when i tried to reinstall ox lion it didnt show any disk what do i do?

    someone help me plz thanks.

    The internal drive has failed.
    Make a "Genius" appointment at an Apple Store, or go to another authorized service provider.
    Back up all data on the internal drive(s) before you hand over your computer to anyone. There are ways to back up a computer that isn't fully functional — ask if you need guidance.
    If privacy is a concern, erase the data partition(s) with the option to write zeros* (do this only if you have at least two complete, independent backups, and you know how to restore to an empty drive from any of them.) Don’t erase the recovery partition, if present.

  • HT1948 USB drive with install image is showing in Startup Manager on a Mac Pro, but wont boot. Showing circle with cross strip, and shut down automatically. USB device are made and work on two different MacBook Pro, but used on Mac Pro. Any help?

    OS X installers have always been fairly specific, hardware-wise. I haven't read anything reflecting that situation with the Recovery HD, so it may be that the Recovery HD created for the MacBook Pro does not have the necessary drivers for the Mac Pro. Obviously, nothing definitive here, but a possibility.

  • MacBook Pro Won't Boot, Hard Drive Full

    Ok so recently my Hard Drive became full and I thought that I would clear up some space eventually but I wasn't going to delete files just yet so I switched my laptop off.
    Now when I go to turn my MacBook Pro (2012 model, 13-inch, 4gb ram, 500gb hard drive) on it gets stuck on 50% of the load bar and it simply will not budge from there. I have gone into recovery mode with cmd R and verified and repaired my Disk which wasn't even damaged in the first place. And I tried to reinstall Yosemite but couldn't  because of the lack of free space needed.
    I reset the nvram (pram) multiple times and it still wouldn't start.
    Then I tried to boot into safe mode which still didn't allow the bot sequence to finish.
    Finally I went into single user mode and run the code: fsck -fy and the hard drive was fine. So finally, I felt like I had to delete files using the single user mode, but I have no idea about the entire UNIX system so I am really stuck.
    I used this blog to get started: http://www.curphey.com/blog/2012/10/24/mac-wont-boot-full-disk/
    first of all I didn't get the log into your  root account bit at the start because mine just went straight to the terminal like black page and so I mounted the disk so that  it was writable with the sudo /sbin/mount -uw / code. However, now I am completely lost. How do I navigate to the downloads folder and actually delete the files
    ?? Could anyone please give me line by line code to do this? Or otherwise is there any other way I can start my Mac up again? I need it for Uni desperately.

    From single user mode:
    cd /
    cd /Users
    ls  <-- (a lower case L)
    cd <youraccountname>
    cd Downloads
    ls
    Then: delete <filename> , if it won't let you try: sudo delete <file>

  • My Macbook Pro won't boot up, I don't have any discs...bought from Craigslist

    I bought my Macbook Pro (2012 model) from Craigslist and only had it about a week, but this morning I couldnt boot it up.  I didnt get any discs with this computer. Only the powercord.  What can I do to get it to boot up and where can I go from there?  There was a software update last night and this morning it won't boot up.  Is my only option going to Apple Store? Is there anything else I can try to at least get it to boot up??  Thanks so much. 

    Yea, it has Mountain Lion on it. I have tried starting while holding down Command-R, and also the Comand R, Option P, and still won't let me boot up.  I made an appointment for a Genius Bar... Is this who I make the appointment with for help with this?  We checked the seriel number from "About this Mac" and we went to view that it had a few years left of apple care. It happened right after a software update.  Wonder if that caused it. Is there viruses out there for Mac's and should I have a program to clean it up after I get it going or IF I get it going tonight?  Thanks,
    Curt
