Help--why has MacBook screen gone dark and how do I get it back?

I have a  MacBook (model 4,1  running OS 6.8).  I use the MacBook as my desktop computer in conjunction with a separate desktop monitor. Today, when I unplugged a USB hub from one of the ports (after carefully ejecting anything on the desktop that needed to be ejected before unplugging), the screen on the MacBook--not the separate monitor--suddenly went dark.  I thought it had gone to sleep or into screensaver mode, but noticed that the white light on the MacBook also wasn't showing. 
The separate monitor display (on which I'm typing this message) seems fine.  I checked DIsplays/Arrangement in System Preferences, but both displays were detected in their usual arrangement, though I did notice that the working display has a white bar across the top but the MacBook display doesn't have one.  I clicked "Detect Displays," but that didn't change anything.
I then did a restart, and things seemed to go as usual:  the shutdown went okay and on restart, the white light went on on the MacBook and the monitor screen lit up normally.  However, the MacBook's screen is still dark and the white light is off.
Can anyone tell me why this happened and how to get my MacBook screen back?  I don't know whether unplugging the hub caused the problem or whether it was just a coincidence that something that runs the MacBook display happened to fail right then.  Would appreciate any help out there very much--thanks!
PS: Just tried shutting down and powering on again with the separate monitor unplugged, but the MacBook screen still stays black and the white light shuts off as soon as the desktop loads.  When I plugged the separate monitor back in, it worked fine.  So the problem doesn't seem to be a conflict with the separate monitor (which I've used for years).

Update:  I went away for an hour, and when I came back I saw that the white light had gone on as usual when the MacBook went to sleep.  When I touched the keyboard, both displays went on; however, the MacBook display went dark immediately and the white light is still out.

  • Why did my Address Book disappear and how can I get it back?

    The Address Book application has simply disappeared on two of my MacBook Pros. I thought the first one (work laptop) was a fluke but now that it's happened on my own MacBook I think something is wrong.
    The app is no longer available anywhere on my hard drive. It's as if I threw it away, but I didn't. I can't open any associated files, so I don't even know if the data has been preserved.
    Can anyone help me figure out why it disappeared, where it went, and how to get it back, short of reinstalling OS X 10.5.8 (the version I'm currently using)? I want to upgrade to Snow Leopard (not Lion -- no one seems to like it), but I'd like to fix this problem first. And I can't upgrade on the work MacBook because I have to use the enterprise-approved OS version.
    Thanks!

    Amy, is there a chance they could both be Syncing to another device that has the data erased?
    What are the sizes & modification dates on the files you found?
    Could be many things, we should start with this to be safe, though 2 different ones would seem unlikely to be this problem...
    "Try Disk Utility
    1. Insert the Mac OS X Install disc, then restart the computer while holding the C key.
    2. When your computer finishes starting up from the disc, choose Disk Utility from the Installer menu at the top of the screen. (In Mac OS X 10.4 or later, you must select your language first.)
    Important: Do not click Continue in the first screen of the Installer. If you do, you must restart from the disc again to access Disk Utility.
    3. Click the First Aid tab.
    4. Select your Mac OS X volume.
    5. Click Repair. Disk Utility checks and repairs the disk."
    http://docs.info.apple.com/article.html?artnum=106214
    Then try a Safe Boot, (holding Shift key down at bootup), run Disk Utility in Applications>Utilities, then highlight your drive, click on Repair Permissions, reboot when it completes.
    (Safe boot may stay on the gray radian for a long time, let it go, it's trying to repair the Hard Drive.)
    If perchance you can't find your install Disc, at least try it from the Safe Boot part onward.

  • Where, O where, has my address bar gone? (And how do I get it back?)

    My location bar has disappeared. There is only the search bar. I want two separate bars, not one. How do I get back my location bar?

    You have the Classic Theme Restorer extension and that makes the Navigation Toolbar work differently.
    You can check the settings of this extension in its Options/Preferences in Firefox/Tools > Add-ons > Extensions.
    It is also possible to hide the Navigation Toolbar when CTR is installed and enabled.
    Make sure all toolbars are visible.
    *"3-bar" Firefox menu button > Customize > Show/Hide Toolbars
    *View > Toolbars<br>Tap the Alt key or press F10 to show the Menu Bar
    *Right-click empty toolbar area
    Open the Customize window and set which toolbar items to display.
    *"3-bar" Firefox menu button > Customize
    *if missing items are in the Customize palette then drag them back from the Customize window on the toolbar
    *if you do not see an item on a toolbar and in the Customize palette then click the Restore Defaults button to restore the default toolbar setup
    You can try to delete the xmlstore.json file in the Firefox profile folder.

  • Why has theDownloads window been removed? How do I get it back with full functionality and Window Title?

    Windows 7 32-bit. Firefox 21

    The Downloads window was removed in favor of the new download toolbar button and panel.
    * [[Find and manage downloaded files]]
    You can re-enable the old Downloads window as follows, but this workaround may no longer have an effect at some point in a future version.
    # Type ''about:config'' into the address bar and press Enter.
    # Press the big button to bypass the warning.
    # In the search box, paste ''browser.download.useToolkitUI''
    # In the search results, double-click ''browser.download.useToolkitUI'' to set its value to '''true'''
    If you're missing any feature of the old Downloads window, try a download manager add-on.

    Take each of the following steps that you haven't already tried, until the problem is resolved. Some of these steps are only possible if you have control over the wrieless router.
    Step 1
    Turn Wi-Fi off and back on.
    Step 2
    Restart the router and the computer. Many problems are solved that way.
    Step 3
    Change the name of the wireless network, if applicable, to eliminate any characters other than letters and digits. You do that on your router via its web page, if it's not an Apple device, or via AirPort Utility, if it is an Apple device.
    Step 4
    Run the Network Diagnostics assistant.
    Step 5
    In OS X 10.8.4 or later, run Wireless Diagnostics and fix the issues listed in the Summary, if any.
    Step 6
    Back up all data.
    Launch the Keychain Access application in any of the following ways:
    ☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
    ☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
    ☞ Open LaunchPad. Click Utilities, then Keychain Access in the icon grid.
    Enter the name of your wireless network in the search box. You should have one or more "AirPort network password" items with that name. Make a note of the name and password, then delete all the items. Quit Keychain Access. Turn Wi-Fi off and then back on. Reconnect to the network.
    Step 7
    You may need to change other settings on the router. See the guidelines linked below:
    Recommended settings for Wi-Fi routers and access points
    Potential sources of interference
    Step 8
    Make a note of all your settings for Wi-Fi in the Network preference pane, then delete the connection from the connection list and recreate it with the same settings. You do this by clicking the plus-sign icon below the connection list, and selecting Wi-Fi as the interface in the sheet that opens. Select Join other network from the Network Name menu, then select your network. Enter the password when prompted and save it in the keychain.
    Step 9
    Reset the System Management Controller (SMC).

  • After connecting my iPhone to my Macbook Pro to download photos to my phone, my pages application is now gone from my computer. The icon is still in the dock. What happened and how do I get it back?

    After connecting my iphone to my Macbook Pro to download photos to my phone yesterday, my Pages application is gone from my computer. The icon is still in the dock. What happened and how do I get it back? Its not in my trash or anywhere else.

    The other 2 applications open like normal. All three give me info.
    Pages     ver.4.1          265.8MB
    Numbers ver. 2.1          89.5MB
    Keynote ver. 5.1.1        238.1MB
    They all list Apr 3 as the last time opened. That was when I upgraded to Mavericks. I certainly used pages and numbers since then as I have alot of my work files on this computer?
    Just very odd. I did find my original iWorks disc from when I bought the computer. I'm assuming i can reinstall it. Will try that. Thank you for all your help. Would still like to know what did happen?

  • All my windows live messenger contact have disappeared of windows messenger and appeared in my phone contact list on my curve 9360, Why, and how can I get them back where they should be?

    I went onto windows live messenger today and all my contacts have disappeared from it, but I also noticed that they had somehow now appeared in my curve 9360 phone contacts. How did this happen, and how can I get them back into windows live messenger and out of my phone contacts on my phone? This is driving me crazy, can anybody help please?
    My phone is the curve 9360, OS is 7.0.0 bundle 2259 And it was purchased Easter Monday
    Thanks.

    Thanks, but I checked iCloud and it has none of them.
    If it backed up to my laptop, that died and I just got the new computer. The one that's crashed won't even boot, so there's no way to even tell if it was syncing the contacts along with all the phone photos. Literally happened at the same time - it was because I had the new computer that I was finally able to pull the photos off the phone and make room for the upgrade. It had refused to upgrade for lack of space for some time.
    I had thought it was set to sync to iCloud but it vanished from BOTH my phone and the cloud. That's why I'm so angry about it.

  • Ipad2 gives me ""accessory is not supported" message w/ VGA adapter that I used lots of times before. Now it's not working. Why? and how do I get it back to normal functioning?

    Ipad2 gives me ""accessory is not supported" message w/ VGA adapter that I used lots of times before. Now it's not working. Why? and how do I get it back to normal functioning?
    I used the (Apple branded) VGA adapter lots of times last year. Now I got back to one place I used it many times and it does not work. When I restart iPad with the adapter connected, I get the "accessory is not supported"message. But that same accessory WAS supported before.
    This is very annoying as I planned a whole bunch of presentations starting this week to do with my iPad2 and that adapter.

    I received the same error message, "Accessory Not Supported"  from both the VGA and DV video adapters I purchased, both were boxed direct from Apple. However, to bypass this problem I  simply clicked on Photos icon on iPad2 and flipped through photos until it displayed on my projector.  I then exited the Photos app and my home screen displayed fine on the projection screen.
    Some logic issue with the video adapters, but launching Apple Photo app initializes the video adapters then they work fine for mirroring after that.
    Platform: iPad2
    IOS: 5.1.1
    Best regards!

    Double click on the picture of the HD on your desktop, then look at the bottom of the window that opens.
    First check the S.M.A.R.T. status on your HD: Applications > Utilities > Disk Utility > in the panel at left, select the first item in the list/your HD mechanism > look atthe bottom of the main window next to S.M.A.R.T. status and see if it says “Verified” or something more ominous like “Failing.”
    If S.M.A.R.T.status is "Verified," run Repair Disk: Boot from install disc (insert disc > restart > immediately hold down c key and keep holding it until you see “Preparing Installation”) > at first screen select the language and click Continue > click on the Utilities Menu in the menu bar > open Disk Utility > select your HD in the panel on the left side > click Repair Disk at bottom of main window. Run this at least twice, and keep running it until it says “appears ok” twice in a row. If that doesn’t happen, you may need a stronger utility such as DiskWarrior or if the directory is damaged beyond repair, you may need to reinstall the OS, or you may have a damaged HD (repair utilities can only repair the directory structure, not the HD itself). When this is finished, quit Disk Utility, quit the installer, and restart. Once booted normally, go to Applications > Utilities > Disk Utility and run Repair Permissions.
