My screen on my mac book pro goes blank for no reason when I use f1 and f2 keys it comes back

You can blank the monitor using those keys, that's likely what you did, it's a feature.

  • Screen on my Mac Book Pro goes out randomly when I touching trackpad.

    The screen on my Mac Book Pro goes out randomly when I touch my trackpad.  Every time the screen shuts off, I have to restart my computer so the screen will turn on again and it's driving me nuts.
    Does anyone have any idea why this is happening and a solution?
    Thanks

  • My screen on my mac book pro is black. I can see the mouse, but nothing on the screen

    Please help! My computer has been perfectly fine! I get home and turn it on, and it boots up just fine, but my screen is black. However, I can see the mouse but nothing else. What do I do!?

    Try resetting SMC and NVRAM and then reboot.

    Try booting the Recovery Partition.  Power off (hold the power key down for 7 to 10 second).  Boot and hold down the Command and R keys.  Is the screen still black?  If so it is not a software problem so take it in for diagnosis and repairs.  Make a Genius Bar reservation http://www.apple.com/retail/geniusbar/ or find an Apple Authorized Service Provider https://locate.apple.com/country .

    You have the misfortune of having a model identifier 6.2 MBP that is experiencing GPU problems.  There was a replacement program on these units, but that has expired.
    The solution is to have the logic board replaced, but that will be at your expense.
    A temporary solution is to download this application which will allow you to disengage the discrete GPU and run only on the integrated one.  Graphics performance will be degraded.

    Adding the shift key to the command places the screen shot in the clipboard as Hiroto pointed out.
    To get the file on the Desktop just remove the shift key.

  • Kernel panic and distorted screen on startup - mac book pro c.2008 on os x 10.4! HELP!

    I've had my mac book pro since 2007/8, it's on os x 10.4, and has worked well until last night when the screen froze in a crazy distorted pattern and I had to turn it off. Now it kernel panics every time i turn it on and it attempts to start up with the same crazy distorted pattern across the loading screen and even the kernel panic message.
    I don't have the start up discs with me.
    I've tried the troubleshooting for kernel panics i.e.
    1. holding [shift] when start up  - did nothing
    2. holding [option + command + p + r] when start up - chimed three times but wouldn't load  after this
    3. holding [command + s] on start up to boot in single user mode - it loads the logs but with the same crazy distortion and when i try to exit to boot in single user mode it won't do anything
    so that is where i am up to... really need my laptop for work and about to leave the country to travel so need it asap - i'm in melbourne and the apple store is miles out of city - any suggestions on reliable apple retailers also gratefully received...
    anyone any ideas on the damage/ cause/ possible solution???
    i love my mac. please don't die.

    If this happened spontaneously and not as the result of a software update or any other change that you made, then it's probably due either to a hardware failure or to data corruption. There isn't much you can do without the installation disc, and maybe not even with the disc. If you can boot in single-user mode, run fsck as prompted on the screen. If it finds problems, run it again.
    Any authorized Apple dealer should be able to provide service, but it may take more time than you have.

    My Mac Book Pro had a split drive with Windows Microsoft Access on it and it was removed when Mavericks installed.  I need this so how can I go back to the old system?

    Restore from the backup you had prior to installing Mavericks.
    However, the upgrade should not have altered your partition scheme. Did your erase and format the drive prior to upgrading?

    " how can I sync my iphone to my mac book without losing all the music and pictures on it?"
    You cannot.  Copy everything you want form the old computer to the new one, then sync it.
    it basically says you have to erase your iphone to sync to a new itunes!
    Correct Iphone will sync, or manually manage, with one and only one computer/library at a time. Syncing, or manually managing, to another will indeed erase the current content.

  • I am having trouble getting my My Mac Book Pro 15" Retina to wake up with an Apple Bluetooth Keyboard and Mouse while Docked in a Hengedock vertical docking station.

    I am having trouble getting my My Mac Book Pro 15" Retina to wake up with an Apple Bluetooth Keyboard and Mouse while Docked in a Hengedock vertical docking station. The Keyboard and mouse work great with the laptop lid open but when closed in the docking station the bluetooth signal does not seem to transmit.  Is there a setting that can be changed to allow an Bluetooth keyboard and mouse to wake the computer while docked?

    Please read this whole message before doing anything.
    This procedure is a diagnostic test. It’s unlikely to solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
    The purpose of the test is to determine whether the problem is caused by third-party software that loads automatically at startup or login, by a peripheral device, by a font conflict, or by corruption of the file system or of certain system caches.
    Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards, if applicable. Start up in safe mode and log in to the account with the problem. You must hold down the shift key twice: once when you turn on the computer, and again when you log in.
    Note: If FileVault is enabled, or if a firmware password is set, or if the startup volume is a Fusion Drive or a software RAID, you can’t do this. Ask for further instructions.
    Safe mode is much slower to start up and run than normal, with limited graphics performance, and some things won’t work at all, including sound output and Wi-Fi on certain models. The next normal startup may also be somewhat slow.
    The login screen appears even if you usually login automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
    Test while in safe mode. Same problem?
    After testing, restart as usual (not in safe mode) and verify that you still have the problem. Post the results of the test.

    Open your Displays system preferences.  Is there an Arrangement tab and does it show two screens?  If no Arrangement tab then your mac does not know it has two screens.  Maybe smc and pram reset will shake it free and maybe not.  Maybe there's something wrong with the connection.  Thunderbolt plugs are similar to mini-displayport plugs so make sure the plug is pushed firmly in so that essentially all the metal part disappears inside the socket.  The plugs can be a little tricky in that you need to make sure the plug is fully seated in their socket.
    If you do see two screens in the Arrangement tab then click Detect Displays and Gather Windows to get the Displays preferences of the other monitor on to your main monitor.  Check the resolution and if there is a refresh rate check that as well.

  • Ever since I updated to Yosemite my mac book pro keeps asking for Apple Id and password but will not accept them

    Ever since I updated to Yosemite my mac book pro keeps asking for Apple Id and password but will not accept them.  What can I do?

    Try the advice here. I had the same problem and it worked for me.
    You have to delete the "SC Info" folder from /Users/Shared. You will have to use Terminal to enable you to see this folder first. Make sure iTunes is not running when you delete the "SC Info" folder
    There is an article from Apple on this here. The "SC Info" folder contains iTunes authorization information.
    I did this two weeks ago and iTunes accepted by login. I haven't been asked for my AppleID or password since.
