Why does the screen on my MacBook Pro keep going black? It happens randomly. Please help.

No patterns, it just crashes. Happens every couple of days or so.

try these :
Hold down SHIFT - CTRL - ALT(Option) same time with the POWER BUTTON for a quick 2 seconds then let go and normally turn on your computer

  • HT1338 The screen on my MacBook Pro keeps going black.  This is happening more frequently.  I have had it in to the Apple store multiple times and they can't find a problem.

    My MacBook Pro screen keeps going black.  This is happening more frequently.  I have had it in to the Apple store several times for this and they can't find anything wrong other than it is locked up for a while.  Since it is happening more and more, I am worried that at some point this will be permanent.

    Has it actually happened at the store?
    If not then we need to get it to do that. Now it may be completely random but you need to try and make a note of as many things as possible that happen when it does it.
    How long has it been on for, what are you doing at the time, what's connected. If it's reproducible then you've at least got somewhere.

  • My screen on my MacBook Pro keeps going black

    I got my MacBook in September of 2010. It's a 2.66 GHz Intel Core i7 with 4 GB 1067 MHz DDR3. I have had great luck with it, until recently. This problem has been going on since like August now and it's time I should quit ignoring it. For some reason when I am just using my computer normally my screen goes black. Everything seems to be disabled but the keypad still lights up. The only way to get my macbook working again to to forcefully shut it off and turn it back on. Sometimes when i use the mouse a certain way (such as sliding 3 fingers to view other open windows) it shuts off. I have also updated my software from Snow Leopard to OS X Lion. I don't know what could be causing it. I have had some issues sending in laptops before to get fixed but I have a feeling it's going to come down to that. I'm a college student and use my computer daily and being a broadcasting major I need this computer for everything I do. Can somebody please help?

    I had similar problem with my MacBook Pro. Login window goes black in 4 seconds, but it is not turned off. Push power and screen comes back but goes black again in 4 seconds. I can type in password, but before it logs me in, it goes black.   If I connect to external monitor, the screen stays up, and I can use extermal mouse but keyboard input is ignored.  This was obviously display problem of the Mac, at the least. (no clue why keyboard does not work when connected to external monitor.
    I have solution: Reset PRAM
    1. Power down Mac compeltely.
    2. Hold down Option, Command, P and R keys (four keys total) while you press power button to boot up Mac
    3. Mac will restart at least twice. Listen to noise.  After 2nd power up, lift all keys.
    I kept holding down the keys and Mac restarted like 5 times before I released keys, then rebooting stopped. Mac now works. The article I read said "wait for 2nd reboot". I though it would stop after twice.
    In my case, I think use of extranal monitor confused Mac Book Pro eventually. I see no other side effects (such as loss of data on hard disk, resetting clock, resetting default settings etc) while I do reset, so I think this is relatively safe thing to try.

  • Why does the display on my 27" iMac keep going black?

    This seems to be happening very often now. It started with just every once in a while.
    I will be using my iMac and the display goes black. It does NOT go to sleep. Just the display goes black. I do video and audio editing on my iMac and if I am listening to playback or a song while the screen goes black, I can still hear it. So, I know it has not gone to sleep.
    A way that I have gotten around this is by, once the display goes black I will then push the power button to make the iMac go to sleep. Then, I will push it again to wake it up. This usually works and the iMac will work just fine afterwards. Now what is happening, the iMac will go black again after a few seconds of being turned back on from sleep.
    I tried to run a diagnostic with an Apple person over the phone and for some reason my iMac will not respond to this.
    AND... It has gotten worse. I can't even boot up my iMac from a power down without the display going black.
    Any help?

  • Why does the volume on my MacBook Pro change on its own?

    I just got my MacBook Pro and sometimes the volume goes up or down and usually when this happens iTunes opens up and starts playing randomly. Why does this happen!?

    No. Have Apple fix this little problem before it becomes a bigger one.

  • Why does the sound on my MacBook pro turn up automatically?

    I recently did a small update to my MacBook Pro.
    Everything was fine until my volume went up automatically, and I could not turn the volume down.
    The only way I can turn the volume down is if I close my computer and open it again.
    I do have an Apple TV, I don't know if this has anything to do with it. The remote for the Apple TV was not touching anything when the volume automatically shot up.
    How do I get this problem to stop?

    Hello bdockery
    Try turning off the IR sensor if your MacBook Pro has one. Check out the steps in the article below to get that sorted out and see if it starts to happen again.
    Pairing your Apple Remote with your computer

    Thanks by advance
    Jean-pierre

    Sorry, I am sending now the image again:
    Anyway, my screen is getting back to normal now (it is just light blue) but I am curious to understand why it happens (just after 2 months it happened again).
    In the country where I am right now we don't have an Apple Store, so any recommendation how I can find out if the problem is the screen or graphic card/sub-system?
    Thank you so much

  • Can anyone help read my crash report? My 2010 macbook pro keeps going black screen with looped sound

    I've had this laptop since 2010 and it's been pretty good up until about two months ago when it would just randomly crash. The screen would go black and if there was sound going on, the sound would just loop on that single second like a broken record. The only way to get it out of that is to hold the power button and then turn it back on. When these crashes would happen in the beginning it would only be when I had Adobe Photoshop running, now it just happens whenever I'm simply using the internet browsing through Tumblr, Youtube, and Facebook.
    Every time I turn my computer back on I get a crash report like this:

    First, uninstall the third-party software that installed these extensions:
    com.vara.driver.VaraAudio          1.0.3
    com.Cycling74.driver.Soundflower          1.6.2
    com.pctools.iantivirus.kfs          1.0.1
    Remove the Dell mouse and use the original mouse.
    See if the above help. If they don't:
    The problem is likely due to the discreet GPU failing. Download gfxCardStatus 2.3 and use it to disable the GPU. This is a temporary workaround until you get your motherboard replaced.
    MacBook Pro (15-inch, Mid 2010)- Intermittent black screen or loss of video

  • HT4623 we cannot get past the screen that says ios6 - then it goes to connect to itunes please help

    Please help we have the iphone 4 and phone is just serching, we then have ios6 on the screen and then goes to connect to itunes, my parents have a pc but my dads itune details are coming up on itues we do not want to confuse the issue and loose our data on either phones, what can i do?

    hello

  • Why did the screen on my MacBook Pro turn black and ask me to hold down the power button to restart and then when I restarted it. ALL the work i had done was gone???

    How do I get back what I lost. When I was forced to shut down my computer?

    None of us knows why your screen turned black - it's the most serious form of crash, and yes, almost all the changes that you didn't save are lost.
    An exception are the audio recordings - they should still sit in the project package of your song. Locate the project in the Finder, ctrl-click it and select "Show package content". The Media folder will contain all your recordings.

  • Why do the applications on my Macbook Pro keep crashing?

    Hello everyone,
    Every time I'm using my Macbook, either Safari, Google Chrome, iPhoto, Microsoft Office Programs, etc. always crash. Recently Safari crashed and I was wondering if someone could explain what the crash report is saying. Thank you for your time.

    In every case I've come across where the cause of this crash could be determined, it was caused by faulty memory. Sometimes a system update seems to bring out the fault. See, for example, this thread:
    After the latest update, Safari is quitting unexpectedly
    It would be reasonable to try reinstalling OS X, but I doubt that there will be any change. You could also try the extended version of the Apple Hardware Test, but it misses memory faults more often than not. If you've upgraded the memory, reinstall the original modules and test, being careful not to touch the gold contacts. Clean them with a mild solvent such as rubbing alcohol.

  • Why does the back light on my Tour keep going in and out?

    All of a sudden (over the 4 or 5 days) my battery is draining very quickly.  I take my phone off the charger at 8:30am and by the time I am driving home from work @ 5:00pm the battery is completely dead.
    I also just noticed that there is something wrong with the back light dimming.
    You know how if you don't touch your phone for a long period of time (mine automatically locks) then the back light dims slowly to black.  My phone doesn't light up again until you touch a button or do something to the phone.
    Since I have been having battery problems I noticed that after prolonged none use my phone dims to black and then immediately lights back up again on its own. And it continuously does this all day long, which is why I think it is killing my battery.
    Anyone know why this is happening?  I tried turning the phone off for awhile and then back on....nothing seems to help.
    Help!

  • Why does the screen on my iPad mini jump around?  Apps open and close, I can't get back to the home screen.  Is my mini possessed?

    Why does the screen on my iPad mini start jumping--larger, smaller--can't close apps.  I reboot and still it happens.  Any suggestions?

    If the unit has NEVER been jailbroke, first try a system reset.  It cures many ills and it's quick, easy and harmless...  Hold down the on/off switch and the Home button simultaneously until you see the Apple logo.  Ignore the "Slide to power off" text if it appears.  You will not lose any apps, data, music, movies, settings, etc.
    If the Reset doesn't work, try a Restore.  Note that it's nowhere near as quick as a Reset.  It could take well over an hour!  Connect via cable to the computer that you use for sync.  From iTunes, select the iPad/iPod and then select the Summary tab.  Follow the on-screen directions for Restore and be sure to say "yes" to the backup.  You will be warned that all data (apps, music, movies, etc.) will be erased but, as the Restore finishes, you will be asked if you wish the contents of the backup to be copied to the iPad/iPod.  Again, say "yes."
    At the end of the basic Restore, you will be asked if you wish to sync the iPad/iPod.  As before, say "yes."  Note that that sync selection will disappear and the Restore will end if you do not respond within a reasonable time.  If that happens, only the apps that are part of the IOS will appear on your device.  Corrective action is simple -  choose manual "Sync" from the bottom right of iTunes.
    If you're unable to do the Restore, go into Recovery Mode per the instructions here.  You WILL lose all of your data (game scores, etc,) but, for the most part, you can redownload apps and music without being charged again.  Also, if you have IOS-7, read this.

  • I have a very tiny, fuzzy black speck on the screen of my Macbook Pro 15".

    I have a very tiny, fuzzy black speck on the screen of my Macbook Pro 15". It doesn't resemble dead pixels I've encountered in the past (it is only visible behind a white or brightly colored background), and I'm positive it isn't sitting on the surface. The computer is only a year and a half old and my software is up to date.

    Hi austinbread,
    It is hard to tell exactly what your issue with the MacBook Pro’s display is, but it is possible that there is a pixel anomaly. See this article for further information -
