My laptop has just shut down and won't power up

I have a MacBook Pro laptop. When I turned off the alarm it just went black. I tried to restart it but it was unresponsive. After 2 hours I was able to restart it but it has since been randomly blacking out or parts of the screen will be blacked out.

The startup disk may need repairing ...
Restart your Mac while holding down the Command + R keys. From there you should be able to access the built in utilities to repair the startup disk if necessary, or restore OS X using OS X Recovery
Be aware, OS X Recovery requires a high speed broadband connection.

  • My iPhone 5s has just shut off and won't turn back on. Please help?

    I was just chatting on a app and the phone just froze, went to a white screen with the apple trade mark. Then it completely shut off and wouldn't turn back on. I tried charging it and it still won't turn back on.

    Thanks for the advice but I've tried this it hasn't worked. I've held down both buttons together for more than a minute. Do I have to hold them down longer than this?

  • My iPhone 4 has just shut down.  Rang the phone then vibrated for 2 minutes bank screen, will not turn on, also tried charging and will not charge.  Any suggestions

    my iPhone 4 has just shut down.  Rang the phone then vibrated for 2 minutes bank screen, will not turn on, also tried charging and will not charge.  Any suggestions?  I did download a ringtone app and went on to iTunes to sync!. 

    Try charging the iPhone via a wall socket for at least 30 minutes then try a reset by pressing and holding the sleep/wake button and the home button for 20 seconds (maybe longer) until the Apple logo appears, ignore the red slider.  Then turn back on. You won't lose any data doing the reset.

    Have you tried holding the power button down for several seconds? I would try the force quit as mentioned earlier first, or go to the Activity Monitor in Applications>Utilities and try force quit there.

  • My iPhone 4 shut down and won't turn on again.What should i do?

    My iPhone 4 shut down and won't turn on again. I tried charging it and do it again...When i charge it , it opens the " Connect to iTunes" , when i switch to the computer to connect it , it doesn't work... It starts to the apple screen , and then just shuts down again. I tried holding the home and sleep/wake button at the same time..I tried everything. What should i do?

    Your iPhone is going back and forth between recovery mode and powering on which is really strange.
    Have you tried a hardware reset while its connected to your computer? This will force it back into recovery mode so that you can restore it. If restoring and setting up as new doesn't help, go ahead and take it to an Apple Store for a replacement

  • Ipad will just shut down and not power back on until it is plugged in

    Ipad will just shut down and will not reboot until it is plugged in. Any suggestions??

    I'm going to guess that your battery isnt just dead?
    Have you tried a reset? Hold down the sleep and home keys, past when you see the red power down slider  and until you see the silver apple. Let it reboot and see if that helps.
    If it won't hold a charge, make an appointment at your local apple store and have them take a look at it.

  • My IPad just shut down and does not want to start again?

    My IPad just shut down and does not want to start again....what can I do?

    Assuming that the battery isn't empty (it can take up to 10 or 15 minutes charging before it responds) then have you tried a reset ? Press and hold both the sleep and home buttons for about 10 to 15 seconds, after which the Apple logo should appear - you won't lose any content, it's the iPad equivalent of a reboot.

  • HT1688 We bought the new iphone 5s when they came out from at&t and my dad has completely shut off and won't do anything? It has not been in ANY water or anything else that could have caused this

    We bought the new iphone 5s when they came out from at&t and my dad has completely shut off and won't do anything? It has not been in ANY water or anything else that could have caused this.

    Try to reset the device:
    Device Reset (won't affect settings/data/music/apps/etc)
    1. Press and hold (& continue to hold) BOTH the Sleep/Wake button & the Home button.
    2. Continue to hold BOTH (ignoring any other messages that may show) until you see the Apple logo on the screen.
    3. Release BOTH buttons when you see the Apple logo and allow the device to boot normally.

  • Adobe Reader is shutting down and won't open

    Adobe Reader is shutting down and won't open, can i get some support?

    Some things to try...
    Using Windows Explorer navigate to C:\Program Files (x86)\Adobe\Reader 11.0\Reader, then double-click on Eula.exe and accept the license agreement
    Can you open Adobe Reader by itself?  If so, try disabling Protected Mode [Edit | Preferences | Security (Enhanced)].
    It could even be a malware issue; see http://helpx.adobe.com/acrobat/kb/reader-core-dll-error.html

  • My iphone just shut down and i cannot get it started again

    my iphone just shut down and i cannot get it started again

    Hey Barry,
    It really depends on the circumstances.  If you haven't powered your phone off yourself for quite some time, sometimes kinks can just happen and this sounds like one of them.  Every so often on mine I will have to use this method but it is in the very minority of occasions.
