Booting up with 0 brightness that can't be changed

I have a late 2010 MacBook Air 11" with Windows 7 / Mac OS X dual boot.
Windows 7 has been working great for a couple of weeks now, but this morning after Windows resumed I was presented with a blank screen (not backlit). I can see the resume animation fine, it's just once it actually goes to the desktop that the screen turns off.
The volume and brightness keys no longer work (with or without pressing the Fn key).
I may have hibernated the laptop with 0 brightness and it is now stuck in that state. I have tried rebooting with no luck. Mac OS and Windows 7 safe mode both work fine.
I tried logging into safe mode and re-installing bootcamp, but it gives me a bluescreen the moment i run setup.exe I also tried uninstalling bootcamp but windows tells me that the installation manager wasn't installed properly.
Is there a config file I can delete or some way to force it to reset the screen brightness from within safe mode? I'm really stuck!

this happened to me last night. i panicked at first but then realized the screen is still there, just not backlit. the trick is to get a very bright light source (i held mine under a bright lamp) and you can move the cursor to the bottom right of the screen and hopefully you'll see your mouse cursor moving around there. then single click on the power icon and select adjust screen brightness. from there you should be able to move the slider back to where you need it. hope this helps. also hoping Apple develops bootcamp drivers to support function key operations (brightness, volume, etc) soon.

  • Is it possible to have a dual boot system with Windows that can ALSO be booted into a virtual machine optionally?

    I have been looking for a solution to this for some time now.  I want the convenience of a virtual Windows environment that can run simultaneously with OS X Lion--something I have right now using Virtualbox.  But at the same time, there are graphics and processor-intensive Windows applications (for me, games and engineering applications) that don't run well at all in a virtual machine.  So, here is what I am looking for:
    A dual boot (i.e. bootcamp) system running Windows 7 and OS X Lion in which the Windows 7 machine can EITHER be booted as a virtual machine while running OS X OR booted physically so as to utitlize all system resources.  The real trick however, is that I I want the virtual machine and the physical machine to be the exact same system.  Meaning, if I boot physically into Windows and change something... rename a file, run a program and create a file, etc...  those changes will all appear in the virtual machine.
    Now, what are my options?  I have read about Virtualbox and VMWare Fusion's "Raw Disk access" function but I can't tell if that's what I'm looking for or not...  I half-thought that they were talking about converting a physical OS into a virtual machine, but without the intention of booting the physical OS again...
    Also, I'm open to any software, free or otherwise.  Thanks!

    both VMWare Fusion & Parallels Desktop for Mac can use a bootcamp Windows installation as VM exactly like you want.

  • How to save a Photoshop PDF file with fonts that can be detected in Acrobat?

    We created a PDF file using Photoshop CS5, for the purpose of using it as a watermark on documents.  We saved this file as Photoshop PDF file, but for some reason the fonts cannot be detected when the file is opened in Adobe Acrobat.
    We need it to be recognized by Acrobat so that we can easily add the watermark to documents on a regular basis.
    Right now, Acrobat cannot detect the fonts in this file -- even though it is a basic font like Arial -- so when we add the watermark to a document, the fonts in the watermark becomes very degraded in appearance.
    Any advice would be hugely appreciated!

    I've tried several settings when saving as a PDF, to try to produce a file with fonts that can be detected by Acrobat.  I tried the presets listed in guide: Photoshop Help | Saving PDF files
    But none have worked.
    I cannot use PNG because it is not one of the formats that Acrobat allows for a watermark.  And JPG doesn't work because I need transparency.

  • Web dynpro screen with multiple rows with columns that can be edited

    Web dynpro screen with multiple rows with columns that can be edited individually:
    Hi
    I am busy creating a screen in web dynpro for ABAP which we would like to make available via Portal ESS (Portal 7).
    I need to add 'n type of table (or almost something like Excel) or something in which someone can type a few paycode numbers (there should be lets say 10 blank rows in which info can be typed in and if I click on a button or so, more rows must be added if necessary.  Then in the other colums stuff like amounts must be entered which one should also be able to edit then and there.
    Can anyone assist in what I can use for this?  There does not seem to be some existing element that I can use.
    Help will be appreciated.
    Regards
    Debbie

    Hi Debbie,
    Whiel Creating table you need to be care full that use chose INPUT FIELD as the CELL EDITOR. Just guessing that if ur table is not editable u might have choosen TextView as default cell editor type.
    check link for details on TABLE UI
    [http://help.sap.com/saphelp_erp2005/helpdata/EN/b5/ac884118aa1709e10000000a155106/frameset.htm]
    easy way is to first add UI ELEMENT TABLE to your VIEW, then right click over it & select create binding from context. After you have a pop up where you can select what columns you want what should be its cell editor etc.

    Hi. When I boot to Boot Camp with the latest Apple Windows Support drivers can't see my USB Flash Drive, DVD and OS X volumes but not my USB external drive that has an MBR partition scheme (using iPartition from GUID) and in there it has different volumes [HFS when I boot to Snow Leopard, Fat32, NTFS]. What can I do with Boot Camp to make it see my USB external drive and why isn't it seeing the USB when it can see the USB flash drive both use USB?

  • Is labview able to communicate with softwares that can simulate dynamics?

    I am currently trying to use labview for my simulation, but it turns out that i still have a long way to go.
    And it would really be pain in the a** if i have to make it all in labview.
    Is there any way that labview can communicate with other software that can simulate dinamics with 3D model also such as (CATIA, NASTRAN, etc)
    -Just a student-

    Hi Nandha,
    Could you please describe exactly what you are trying to do in more details? What kind of simulation are you trying to create? We have several LabVIEW toolkits that might help you accomplish your goals. Please review the following:
    NI Developer Suite Control Design and Simulation Option
    You can click on specific links on the left-hand side of the above-mentioned website. Particularly look at Control Design Toolkit, System Identification Toolkit, and Simulation Module.
    You can quickly create custom LabVIEW user interfaces to verify Simulink models interactively and rapidly build controller prototypes and hardware-in-the-loop test systems based on Simulink models with the Simulation Interface Toolkit. (Simulink is a trademarked product of the MathWorks).
    I also found the following links on www.ni.com related to CATIA, and NASTRAN. VRML files are natively supported in LabVIEW 8.20. You can also input VRML files in NI INSIGHT .
    I hope this helps! Let me know if there is anything else I can do for you.

    im given a period for the sake of this example lets say period 1 i get nothing else. I have to find the greates grant year grab the amount for period 14(which is the total from the previous year) and add it to the amount of the current period. in this case period 1 grnt_year 11

    the current period +(current period - greatest year 00)
    hope that makes sense so in other words with the new data above. if i was querying period two of grant year 11. i would end up with $800
    because the greatest year is 11 it contains a period 0 with amount of $400 so my total should be
    period 2 amount $ 600
    period 0 amount $ 400 - period 2 amount of $600 = 200
    600+200 = $800
    if i query period 1 of grant 360055 i would just end up with 800 of grnt year 10.
    i have tried to modify that query you supplied to me with no luck. I have tried for several day but im embarrased to say i just can get it to do what im trying to do .

  • Create a PDF with DDX that can be converted to PCL by generatePrintedOutput

    Hi all,
    I have a scenario that puzzles me a bit.
    I have some forms that are Interactive forms (stored as XDP with the property Dynamic XML Form).
    I need to assemble these xdp-forms (and fill them with data) and add it all up in one PDF. This PDf should be converted to PCL and later shipped off to a printer. However I see a conflict in doing this by using the Invoke DDX and generatePrintedOutput services.
    I can easily create my PDF, but to make it work I have to include the <NoForms> tag in my DDX. However when I do this I end up with a non xfa-based PDF. When I try to pass this to the generatePrintedOutput service it complains that the form is not XFA-based.
    If I then remove my <NoForms> tag from my DDX I get the error from Assembler telling me that "the baseDocument cannot be assembled becasuse it is an XFA-based form".
    What am I doing wrong? Could you elaborate a little on the behavior of these two services.
    I have found the link to the documentation on page 38 in http://help.adobe.com/en_US/livecycle/9.0/ddxRef.pdf, however I don't think it tells me what is wrong.
    Please advice

    Open in PS and print to the Adobe PDF printer. However, a 448MB TIFF seems huge. At 200 dpi and 24 bit color (millions of colors) that leaves you with a 61inX61in graphic. Even at 600dpi, that is 20X20.
    For us to help you, please indicate exactly how you are trying to convert from PhotoShop. For Acrobat, are you trying to open the TIFF in Acrobat directly? Is the TIFF a single sheet, or multiple sheet? There are a lot of unanswered questions for us.
    One of the limitations on file size is the size of the temporary PS file that is created in the PDF creation process. This PS file is created in the TEMP folder that is limited by MS. So you might try emptying the TEMP folder.

  • Help with photos that can't be imported

    Hello all,
    Every time I open iPhoto there is a message saying new photos have been found and asking if I want to import them to the library. I click "yes" and the same message is shown again.
    After that, I get a message saying the photos have been added to the folder Recovered_Photos_NN.
    The problem is that the folder is empty and that no photos are added to any library. I already have up to Recovered_Photos_25 folder with no photos in it and every time I open iPhoto a new folder will be created.
    I think this happened for the first time once I connected my iPad 1 to the iMac.
    I have never been able to identify what 24 photos they're talking about. It's always 24 photos.
    Can anyone help me to find what's going on?

  • Using a Heiarchical Tree with data that can be grouped

    Hello Forum
    I have been tasked with coming up with a selector for one of our applications that uses a tree. I have built a mock-up using the example provided at Craigs Oracle Stuff (https://sites.google.com/site/craigsoraclestuff/oracle-forms---how-to-s/forms-how-to-create-a-hierachical-tree-form) that subsuitutes our data in the SQL for his, and I have successfully added another loop as the data is located in 3 tables, but have come across a few issues. I have been searching the forums and google, but cannot find anything to solve the issues that I am having. Any help is appreciated. This is being developed in 10g. The data is structured as follows.
    Category(root)
    ID, Name
    1, A
    2, B
    3, C
    SubCategory (Level 2)
    ID, Name, CatID
    1, A, 1
    2, B, 1
    3, C, 1
    Codes (Level 3 and beyond?)
    ID SubCatID Description
    1, 1, 'The, quick'
    2, 1, 'The, quick, brown'
    3, 1, 'The, quick, brown, fox, jumps'
    4, 1, 'The, quick, brown, fox, jumps, over, the lazy, dog'
    5, 2, 'Wafting, zephyrs, quickly, vexed, Jumbo'
    6, 2, 'Wafting, zephyrs, quickly'
    As you can see the codes table has a lot of repeating values that are delimited by ',' (commas). I can produce a tree out of the 3 tables but...
    Problem:
    The description in the codes table can be as many as 255 characters. The tree seems to truncate the values around 60 characters. I am not sure what the maximum data lenghts in the tree are, or if the max lengths are limited by the node or the entire tree. Although the Category and Subcategory names can be as much as 120 characters, they are more typically around 25 characters.
    Could this problem be remedied buy deepeing the levels of the tree by grouping the values in the codes table on the comma delimiters? The max number of commas in the description is 9, so that would make the tree up to 11 levels deep. I know how to get the text between the commas, but am unsure how to link the data back to the parent
    Ex. The tree would be
    A
    ->A
    ->->The
    ->->->quick
    ->->->->brown
    Thanks for any Assistance
    Mike
    EDIT: I found the reason that the label of the node is being limited in length. The limit is actually 50char because of this line in Craig's code in the Create_RG function:
    gc_id := Add_Group_Column(rg_id, 'label', CHAR_COLUMN,50);
    I changed the limit to 255 and now all of the data displays.
    Although working now, I would still like to know id there is a way of grouping the data into the tree view, as this would make the tree much more readable.
