Satellite L850 - 1 H 4 - a strange problem with the FN key

Hello

I have a strange problem on my laptop. When I uninstall my PVAT my start "FN" key works, when I install it it s not working not properly. Its market not only the volume key (F9 and F10) without pressing the "Fn", if I want to press F9 or F10 I have to press FN + F9, even with the rest of the buttons.

When I install PVAT I have to press FN, so I can use my F keys (e.g. F3 to search on the browser tool, alt + f4 - I have to press Fn + alt + f4), and I can't use real functions like mute, disable Touchpad etc. Use the volume keys only. Y at - it a problem if I run my computer without PVAT, this may affect its performance?

Where could be the problem and can I fix it? I'm with Windows7 x 64, but the laptop was with no OS when I bought it. And there is a problem with this version, I bought its impossible to install the Pakc3 Service, it s with SP1, can be the problem? I put t know what to do... perhaps I run the laptop without PVAT, sounds good, because the buttons work fine without it, but I don't know if it interacts with something else.

Thanks in advance!

Its possible to use the function buttons by pressing another button without the use of the fn or FN.
This option can be changed in the BIOS.

Go to the BIOS by pressing F2.
In the BIOS, choose Advanced-> system configuration Options
Here you should find the option that allows to change the special function keys which allows you to use the function FN or without button Fn button

By the way: this theme has already spoken here in the forum several times. therefore recommend that you use the advanced search to Forums before posting new thread

  • Strange problems with the database

    Hello

    I just got my Fuze and am very happy with it; However, I am having a very strange problem with the database. I have a 16 GB sdhc card that I use with the "rocket" and there are about 4 songs on the card that will not play and have no information charge tag. Their tags appear in the tag browser (not the in the track information screen) as just an empty rectangle. Under the track information screen, sizes are listed as ~ 4000 mb. The songs will not play and I can not jump in front of one of these songs once they were loaded.

    At first, I suspected some kind of corruption of tag, so I set out that night to track down the problem. I removed the 16 GB card and reset the player. Then, I loaded one of the corrupt in the internal memory of the player. The track has been scanned and played correctly. Then, I removed the track of the internal memory and it loaded on another SDHC card. Yet once, everything worked correctly, so I knew that the card I was using was a kind of system files or physical problem. I returned the original 16 GB sdhc card in the reader and checked that the file was still unplayable, and then I plugged the "rocket" to my computer. I transferred the unplayable file on my computer and compared (with md5sum) to the original file, thinking that if there was the file system or physical corruption the copy of the map would be damaged. However, the files were equivalent.

    To make things even more interesting, I also have problems with the registration of the kind. I have some files tagged Genres such as 'Classic' and 'Rock '. In the list of the genre, I see this:

    C

    CL

    CLA

    CLAS

    Class

    Classic

    Classic

    Classica

    Classic

    Rock

    So, there is corruption on the kind of 'Classic' but not the kind of "Rock". Each of the substrings of 'Classic' contains only a few titles, with most of the other titles listed where they should be. I checked that the tracks are labeled correctly and in exactly the same way as the other tracks that do not have this problem.

    I am at a total loss about what to do, and I'd really appreciate any advice or suggestions. I use the current firmware, 2.03.31a and the songs in question are in Ogg Vorbis format.

    MM

    Thanks for your replies.

    I managed to find what may be the problem. Tracks that received corrupt tags had the names of total path with more than 256 characters. It seems that the driver internal fat32 the rocket uses vomits all over the place when the path name is too long. Before the "rocket", I got an iPod running rockbox tags with the same directory structure that I have on the "rocket", so I don't think that this restriction on the length of the path name is a limitation or requirement of the fat32 file system. Reduce the path corrected the problem with the files being unreadable.

    However, the problem with foires genres the rest. Looking at the files show that corruption, they all have a little information in tags. Most of the information is contained in the hashes I have files that identify them via musicbrainz. The limit on the total number of characters in the tags of the track includes the "rocket" label is not read or use?

  • strange problem with the database link

    Hello world

    I have a strange problem with the link of database in Oracle 11 g Express Edition;
    There are two computers: computer-server and the client computer. Tnsnames.ora are the same on both computers IE.

    CT =
    (DESCRIPTION =
    (ADDRESS_LIST =
    (ADDRESS = (PROTOCOL = TCP)(HOST = krzysztof) (PORT = 1521))
    )
    (CONNECT_DATA = (SERVICE_NAME = XE)
    )
    )

    I created the database link:

    Create database link zdalny
    Connect to < user_id > identified by < password >
    using "CT".

    Customer cannot connect with server when I do not use above the command. But when I change 'use' for using "krzysztof:1521" or by using "krzysztof" or "server IP:1521" - everything is ok.

    Why I ask. Because in all the materials that I read about Oracle command with the help of "CT" should work correct. But there is no. Do you know why?

    Thanks in advance and apologize me for my English.

    Rgds
    Krzysztof

    Here's the tnsnames of your server, but to connect to the oracle server db (any client or to another instance of db oracle), you must install oracle client.
    However, in your condition, you want to connect the DB1 Oracle OracleDB2 using a link db, I'm right? In this case you should always set the entry in the tnsnames.ora
    To verify that you can connect to Oracle DB2 from DB1 Oracle, you can use tnsping in the command line.
    In your case

    c:\tnsping CT

    (CONNECT_DATA =
    (SERVER = DEDICATED)
    (SERVICE_NAME = XE)
    )
    )

    Check your tnsnames entry in the machine, you are trying to connect to. And check if the tnsping is successful.
    Sometimes the error message says not everything, which means that you need to troubleshoot yourself and learn from the experience.
    Always in the opposite case, refer to the documentation.

    See you soon.

  • Strange problem with the formatting of the text

    Hello

    I had a strange problem with the formatting of the text. I created a document in Polish language and the strange thing happens when it divides the word to the next line. For example here on this part of the page, I have a word "umieszczamy", which should be divided "' u - CEF - szcza - my", but my Indesign divides in umi-eszczamy (as shown on the picture). " How can I fix it so it divides the word correctly?

    What language is awarded when you select the text? Hyphenation, but also the spelling, is controlled by the dictionary that is assigned to the text.

    If the language is correct, you might have to change the hyphenation in the user dictionary.

  • Satellite L850 - 17K: sheets of work, but not all the FN keys are available

    Hi everone,

    2 days ago I reinstalled Windows 7 (64-bit) on my Satellite L850 - 17 K.
    I managed to reinstall all drivers, but I had some problems with my function keys.

    After a long search on the internet I found the utility flashcards, but now I don't have 4 flashcards appear (brightness, touchpad, mute, wireless) but only the touchpad function and mute answer. Before you reinstall Windows, I had also a function for the output of the screen which is also shown/not unresponsive.

    The flashcards, I also don't look the same as before.

    Anyone got any suggestions on how to solve this problem?

    Thank you very much!

    Hello

    According to the specifications of the laptop your Satellite was shipped with WIN7 64-BIT Home Premium so I don't understand why you do not use this recovery image that includes all the necessary drivers and tools and utilities.

    Anyway, if you want to have the clean version of the OS all things can be downloaded from Toshiba download page http://www.toshiba.eu/innovation/download_drivers_bios.jsp
    You need to install is that Toshiba value added package and all other tools specific to Toshiba and utilities.

  • Satellite U300-13U - iTunes has detected a problem with the audio configuration

    Please can someone help me? I have a laptop U300-13U and that you have installed iTunes on it. However, when I open iTunes I get an error message saying 'iTunes has detected a problem with the audio configuration and may not play correctly' which is an understatement - it does not at all!

    I uninstalled, reinstalled iTunes and Quicktime, but in vain. I have searched and exhausted the iTunes support boards but have nowhere either. The sound is fine as I can read CDs with no problems at all. The only suggestion I can get is that there may be a problem with the audio device magnet is not Apple and vice versa.

    Does anyone have AN idea at all as to what might be going on here? I'm completely out of my depth, I'm just a simple girl who wants to play his music!

    Thank you so much.

    Hello

    I don t use iTunes so I m not an expert player but first of all, you must give us some important information:
    -What operating system do you use?
    -Are you using the factory settings (Toshiba Recovery disk) or your own version of Windows
    -Do you have the yellow exclamation marks in Device Manager?

    OK, iTunes says that there is an audio configuration problem so do you trying to update the audio driver? If this isn't the case, you should try it.
    See the Web from Toshiba site for an update and see what happens. Then validate your result:

  • Strange problem with the keyboard event listener

    I have a full screen touch app. To close the application, I set an event listener on keyboard for the key "0". I don't want the press user due to some restrictions Alt + F4 key combination. Problems begin when the application loses focus. Here's the code;

    protected function onComplete(event:FlexEvent):void
    {

    this.setFocus ();
    this.addEventListener (KeyboardEvent.KEY_DOWN, trapKeys, true, 0, true);

    }

    private void trapKeys(e:KeyboardEvent):void {}

    If (e.keyCode == 96) {}
    This.Close ();
    }

    Else if (e.keyCode == 48) {}
    This.Close ();
    }

    }

    When the user change the screen to a different with Alt + TAB application, or any other combination of keys flex app loses focus and does not work when he turns back to my app "0". How can I solve this problem?

    Thanks in advance.

    Hi, Ahmed.

    I have absolutely no problem with the solution you are trying to set up - you use mode full-screen interactive mode of keyboard?

    Please consider:

    on full add keyboard listener

    protected function applicationCompleteHandler(event:FlexEvent):void

    {

    this.stage.addEventListener (KeyboardEvent.KEY_DOWN, trapKeys);

    };

    //

    protected function applicationActivateHandler(event:AIREvent):void

    {

    If (this.stage)

    {

    switch the State to display full-screen when activated

    If (this.stage.displayState! = StageDisplayState.FULL_SCREEN_INTERACTIVE)

    {

    this.stage.displayState = StageDisplayState.FULL_SCREEN_INTERACTIVE;

    };

    };

    };

    //

    private var exitHandled:Boolean = false;

    on NUMBER_0 | NUMPAD_0 exit-close

    protected function trapKeys(event:KeyboardEvent):void

    {

    If ((event.keyCode is Keyboard.NUMBER_0

    || event.keyCode is Keyboard.NUMPAD_0)

    (& this.exitHandled == false)

    {

    exitHandled = true;

    this.stage.removeEventListener (KeyboardEvent.KEY_DOWN, trapKeys);

  • Problem with the function keys

    Hi a few days ago my computer did an automatic update of windows.  This combination of time keyboard shortcuts in my Microsoft Flight Simulator 2004 have changed.  For example, ctrl + any Fkey and shift-several different keys do not work.  Some commands are not options in games keyboard assignments.

    Is there a way to restore my original keyboard settings?

    Thank you...

    Are you sure that Windows Update caused this?

    Restore your computer (by using the system restore) to a previous state - before you install the updates and see if it restores the 'fn' and other features with FS 2004.

    See http://support.microsoft.com/kb/306084 (assuming you are using Windows XP, because the game is compatible with XP and legacy OS)

    If restore fixed the problem with the keys on the keyboard and FS2004, manually install the updates one: after the installation of each update, restart the computer, try to play the game and check if the problem reappears at all.

    This, until you have installed all Windows updates.

  • Can not activate Win 8 - reports of problems with the product key

    Hi all

    I have just downloaded 8 Win and tried to upgrade my existing Win 7 Home Premium VM, which I run on VMWare Fusion 5.0.1 on my Intel MacBook Pro 2009. I wasn't able to do the upgrade in place - the installer told me that it was not possible to run Win 8 on this machine. Instead, I created a. ISO file and used to install Win 8 in a new virtual machine. Everything works fine, but I can't activate Win 8. The error message tells me that "something is wrong with the product key" even if I could install Win 8 with the same fine product key.

    I called various hotlines MS today but don't have anything got no solid advice. Am I the only one who experience this issue? Is there something I need to pay attention during installation of the virtual machine to win 8? Is it possible to install a fresh VM with a key product upgrade in the first place? I would appreciate any information you might have on this subject.

    Thank you in advance and Bravo,
