Mac book black screen

Can't turn on my Macbook.
computer light is on but screen is black.
Any fix?

I have the same problem, too.  I have a MBP 15" and all at a sudden, the screen randomly turns black or off.  I need to type my login password to get screen working again.  This is no danger but very incovenience to me. 
However, once I had installed the latest OS X Mountain Lion operating system, this problem just disappeared and now I become a happy guy again loving my MPB 15"!!!  For USD20 only, it is worth a try!!!  Good luck!!!

  • I sprayed glass cleaner directly on my mac book pro screen. Will the screen be permanently 'spotted'????

    Sprayed glass cleaner directly on my mac book pro screen - will the screen be permanently 'spotted'????

    No chemicals should ever be sprayed on the screen of a Mac - they have coatings that can be damaged.  Only use plain water, on a clean cloth that is only slightly damp and do not wipe over the edges of the glass.
    How much damage was done depends on what kind of cleaner was used and how much was sprayed on.

  • MAC SLEEP BLACK SCREEN

    mac sleep black screen needs cursor movement to clear

    I have a variation on this issue.
    We have been rolling out Lion and came accross this issue and applied the fix suggested and it works. However the new twist is that when the user logs in all their apps have shutdown (without savaing).
    For security reasons our company insists that all workstations (Mac or Windows) implement account lock down after 15 mins on inactivity. So I need to find a fix for this.

  • My Mac book pro screen has a constant white mark on it.

    Hi,
    My Mac book pro screen has a constant white mark on it, i have no idea why, its like its inside the screen, its never been dropped or had anything fall on it and the mark is starting to get bigger. Has anyone else had the same problem? i've inserted a pic of it, hopefully you can make it out.
    Thank You

    I see a multitude of white marks on your display.  Your best option is to make an appointment at an Apple store genius bar and have the technicians examine the MBP.  Hardware problems such as this cannot be solved via these forums.
    Ciao.

  • Does anyone know what to do when a apple mac book pro screen won't wake up from sleep?

    Does anyone know what to do when a apple mac book pro screen won't wake up from sleep? I have tried to restart it and it still won't come on.

    Try this, which is located in your macbook pros user manual.

  • Has anyone experience Mac Book Pro screen went alien green and black?

    Hi...I was using my mac when the screen suddenly turned alien green and black, I can still use it though (like save the file and so on). It turn alright after you restart the computer, but I'm afraid if something has gone wrong.Does anyone ever experience the same problem? Does anyone know what is wrong with my mac? I start using this computer since November 2008. Cheers!

    Update:
    I brought it into the Apple Store near my house once. Booted up fine twice. Brought it back, because the green and black vertical lines, and the inversion of colors froze the computer 4 times after the visit. The Apple Genius ran a MacBook Pro NVIDIA graphics card test, which went well until it FAILED one of the tests.
    I had the option to have it fixed in the course of a week, but I thought that since it froze only a few times, that I could work through it (I have important final projects coming up), but now it won't start up. I will have to have Apple ship it away to fix it, because they are behind in their repair shop in the store. So, I will be without it for a week.
    They said it had something to do with the logic board, which I think is part of the motherboard. So, I am glad I backed up most of my projects' data, as they said they might have to erase data when they fix it.
    So, save your files onto external media (HD, flash drive, CDs, DVDs, etc.), and don't let this problem persist; have an Apple Genius check it out, so that you're not in my boat.
    I wish you the best in your troubleshooting!

  • Why does my mac book pro screen go black when it goes to sleep and then will not light up again unless I unplug the power cord

    When I either leave my mac book pro open, but idle long enough for it to go to sleep or close the top and put it to sleep, the only way to light up the screen again is to diconnect the mag. connect power cord. Any ideas why and/or how to  correct this problem?

    So this is what I got when I took my computer into the apple store to have it diagnosed.
    After the apple technician performced several tests, the only thing that fixed the issue was an SMC reset. Based on this he figures it is probably a software or firmware issue that is going on. He is a little concerend how ever that the fans of the comupter don't reach maximal rpm when the computer is displaying the issue. So he recorded the problem, and told me to just perform the SMC reset as needed for the next couple months and wait for a new update from apple. If the issue persists I am to go back to the apple store and they will take the appropriate steps.
    He said an SMC reset doesn't hurt the computer in any way, so its safe to do. I am gonna contact blizzard and let them know about the issue as well because if it is software, it could be their game (Diablo 3) that is causing the issue as well. If I hear of anything new i will let you know. So get on the blizzard form and let them know of the issue to fix the problem faster.
    Thanks for your help,

  • My mac book pro screen is black

    I have a 15 inch mac book pro. I dont know the year or type because i got it as a persent and opened it later. The battery is removable and it is silver. When starting it up it chimes like it normaly would. I just stoped working one day when i got home from school. If i change the volume i can hear the indicator that it is changing. I know you can solve it because other people had the same problem as me. Also the keyboard doesnt work so i use a different one. Can i get this solved without taking it to the apple store. Thanks.

    If the battery is removable, it is pre 2009.
    Try these 2 things, if no joy take to an Apple store for a FREE diagnosis, they will then give you your options.
    SMC reset;
    Shut down the computer.
    Disconnect the MagSafe power adapter from the computer, if it's connected.
    Remove the battery.
    Press and hold the power button for 5 seconds.
    Release the power button.
    Reconnect the battery and MagSafe power adapter.
    Press the power button to turn on the computer.
    PRAM reset:
    ote: To print these instructions, open Help Viewer’s Action pop-up menu (looks like a gear), then choose Print.  
    Shut down your Mac.
    Locate the following keys on the keyboard: Option, Command (⌘), P, and R. You will need to hold these keys down simultaneously in step 4.
    Turn on your Mac.
    Immediately press and hold the Option-Command-P-R keys. You must press this key combination before the gray screen appears. Continue holding the keys down until your Mac restarts, and you hear the startup sound for the second time.
    Release the keys.

  • Slideshow in Lightroom 5.5 Mac Yields Black Screen

    I just discovered that the slideshow functionality in Lightroom 5.5 on my Mac yields only a black screen.
    This is the case for both impromptu slideshows (CMD-Return) and the Slideshow module.
    From a Google search and looking over topics in this forum, I've found other posts describing this identical problem for both Mac and Windows versions of Lightroom going back to the original introduction of Lightroom 5 over a year ago.
    I've been using Lightroom on various Mac computers since the first Lightroom beta release over 10 years ago. I generally don't use the slideshow functionality of the program, so I was quite surprised to discover yesterday that it's not working in Lightroom 5.5. I originally tried to preview/play a slideshow with 100 photos--some Olympus Raw files and some Canon JPEG files. I have since replicated this problem with a test collection of 5 JPEG images.
    I know that the slideshow functionality used to work back in Lightroom 3 and 4. I hadn't tried to use it in Lightroom 5.x until now, so I don't know when it became broken, but it's definitely broken now...and from reading various posts here on Adobe forums and in related non-Adobe forums, it appears that Adobe has yet to acknowledge that this problem exists...which I find surprising and disappointing.
    The only work around seems to be to export a PDF slideshow from the Lightroom 5.5 Slideshow module, which does produce a full-screen slideshow PDF. But, the slideshow functionality should work directly in Lightroom, as well.
    DETAILS:
    Hardware: Mac Book Pro Retina -- fully loaded (2.6 GHz Intel Core I7, 16 GB RAM, Nvidia GeForce GT 750M 2048 MB graphics card, External Apple 27" Cinema Monitor connected via Thunderbolt)
    OS: Mac OS X 10.9.4 Mavericks
    LR Version: Lightroom Mac 5.5
    Problem 1: Impromptu Slideshow (pressing CMD-Enter/Return keys from Library/Develop modules) causes:
    1. spinning beachball for seconds to minutes depending on how many images are in current folder/collection
    2. followed by "Preparing Preview progress bar
    3. followed by entirely black screen. Pressing forwards/backwards arrows do nothing; pressing ESC or mouse click returns to Lightroom module
    Problem 2: Slideshow Module - Clicking Preview button (or Preview triangle under slideshow window) causes:
    1. Preparing Preview progress bar
    2. followed by slideshow window turning completely black.
    Pressing forwards/backwards arrows does nothing; pressing ESC or clicking mouse returns slideshow window to display of slideshow layout
    Clicking the Play Slideshow button exhibits exactly the same behavior as above, except that my entire screen blacks out instead of just Lightroom's slideshow window.

    I’m disappointed

    Update:
    Just upgraded from Lightroom Mac 5.5 to 5.6.
    Per my post above, creating an impromptu slideshow (CMD-Return) or using the Slideshow module produces either a completely black preview or a completely black full-screen slideshow.
    While Adobe addressed other issues and bugs in Lightroom 5.x, they apparently did not address the slideshow functionality in this release, alas....

  • Mid-2010 Mac Mini -  black screen after installing boot camp drivers

    I successfully installed Windows XP Service Pack 2 on my new Mac Mini. The display worked without issue in XP at this point.
    After doing this, I proceeded to install the boot camp drivers. They installed and automatically rebooted the machine.
    After reboot, Windows XP no longer has a functioning display. The display is a black screen and eventually the monitor shuts off.
    Things I've tried:
    - Reset PRAM
    - Reset SMC
    - Tried both Mini DisplayPort and HDMI connections to connect to the HDMI port on the monitor
    - Booting into Safe Mode. Holding down F8 successfully brought up the Safe Mode options, but again the display was blank after choosing the Safe Mode option and attempting to load Windows.
    Message was edited by: mullingitover

    Update: Other stuff I've now tried--
    - Swapping out RAM modules. I've tried it with the stock 2GB sticks in place, also with a single 4GB stick. Same result.
    Other interesting/troubling problems:
    - Unable to boot into Safe Mode with command line. The text-only interface with safe mode options that is reached by pressing F8 during windows startup is displayed. However, no matter which option I choose, the result is a dead display.
    - Unable to boot with Windows XP install CD (?!). After choosing the CD at the boot selection screen, the display blanks and never wakes up.
