  • Why my F11 key does not work

    Using Win 7 64 bit on a Pavilion model h8 - 2260t.   When you try the features on my new HP I find that the key to Fll, which is vital when necessary, does nothing.  Start-up and constantly hit the F11 key is that anything put produce a black screen. I had disconnected my external elements before you try.   I have it benchset for 10 minutes in the hope that he would.  Nothing happened.  If I should have access to the Recovery Manager, using the F11 key, it could not be done.  And of course the discs are not normally provided.

    Any notice or any other action to correct this problem.  Thank you.

    Try to hit the F8 key to ensure that the function of the keys working and also if the F11 key does not is not a problem with the keyboard, it could be a problem with the partition on your system, like why you can't access the recovery through the F11 key Manager. If I were you I would order in addition a backup RCDS from HP directly, if you have these disc you have nothing to fear, even if your not able to sign in to windows.

  • Spectrum 13D-3000: Sound LED (F11 key) does not work on Windows 10 1607

    Hello!

    After the upgrade to Windows 10 1607, I have a problem with the sound led (F11 key).

    It is now always red even if I turn on the sound (by pressing fn + f11 key) or by turning on the sound in the Windows menu.

    Before updating the LED becomes white when I turn on the sound. IDT Reinstaling driver did not help. What can you recommend to solve this problem?

    Mykyta salvation,

    Thank you for your answer!

    Hello!

    I think the best option would be if you connect an external keyboard and test it. You can connect it via USB.
    If you have desktop, take the keyboard and test it on your laptop.

    If the external keyboard works, you need a new internal keyboard. New keyboards are not so expensive then contact ASP and ask for it. ;)

  • Satellite L775 - mouse pad does not work properly

    I have a laptop Toshiba Satellite L775. I run Win 7 Home Premium. My mouse pad does not work properly. I also have a Logitech Anywhere MX wireless mouse. I tried the mouse pad to work properly with the key FN and F9, but it does not work. And you really have no idea if that turns or out of the mousepad anyway, subj for another time I guess.

    What does not work, but I have to do is to go to Control Panel then mouse option load that and just scroll the tabs without changing what each time and then close and the touch pad works. But only for this session. If I have my laptop nearby, or turn it off, I have to start throughout the whole process.

  • The internal keyboard BACKSPACE key does not work

    I have a laptop Toshiba Satellite and the BACKSPACE key does not work.

    He will start work the rare opportunity, but then it just stops working again.
    This happens on everything, including word and internet ect.

    It has been like that for a few weeks now and I turned the laptop and turn off many times.
    Is there a way to fix it myself or I send for repair?

    Please, * don't * tell me:
    Get an external keyboard
    Try it turn on and off
    Just highlight the words and use the delete key - it's annoying to have to do this all the time
    Type carefully and do not make so many mistakes

    Thank you!

    > Please, don't tell me not to:
    > Get an external keyboard

    And why shouldn't t someone recommends you to check the functionality using the external keyboard?

    It s recommended to connect an external keyboard to verify how the BACKSPACE key would work using 2nd external keyboard. In case the back might work properly using USB keyboard, the question is very clear; in such cases its main shortcomings. The key cannot be replaced or changed or fixed. In this case, need to replace the entire keyboard!

    In case the BACKSPACE key does not even using the external keyboard, then this would mean that the internal keyboard controller is faulty and in this case only the replacement motherboard would be useful.

    But to be honest, I think that its simple keyboard failure and a replacement would solve this.

    Hello

    I have a problem with a Satellite C660.
    The keyboard, I cannot use the SHIFT key. After you have installed windows everything worked properly, the problem recurs after a few days. Practically the SHIFT key does not work.
    On the one hand I'm the A and the other side works like ESC.

    Help me I'm crazy.
    Thank you.

    Hello

    To me that sounds more like a keyboard failure, I can't imagine that it could be linked to the question of the windows operating system do you have tested an external USB keyboard.

    Please test this. In this case, you can check if it s really a software problem.
    If the USB keyboard works correctly, it means that your internal keyboard is malfunctioning.

  • FN key is not working properly on my Satellite P875 - 32H

    Hello world

    I have problem like many others, FN key is not working properly. Let's start from beginning:

    1. I bought my P875 - 32 H with Win8 64 bit and everything was allright.
    2. after upgrade to 8.1 probles issued many and most of them I solved it, BUT,
    3 recently, I found that the FN key works in combination with
    (a) f5
    (b) f6, f8 (only with media player works, with winamp does not work).
    (c) f12 (I turned off wifi via Control Panel, but the light still flashes),.
    (d) 1 and 2
    (e) or z (US keybord) - keyboard backligth on/off - I have try several solutions based on the forums (install the driver on toshiba support site) but without success. Throught BIOS I turn on backligth but I can not turn off without entering the BIOS.
    (f) space I've ever used this combination.

    I tried on the Microsoft forums, but there is no solutions.

    And another question
    Why my P875 - 32H model is not on the drop-down list on the toshiba support site?

    Concerning

    At first, I have to say that I hope that you have updated your machine following the instructions on http://www.toshiba.eu/innovation/generic/windows8_1-message/
    FN feature keys is controlled by specific tools Toshiba and you need to install or already installed are Toshiba system driver and utility of Toshiba feature key.

    FN + F5 key combination is for touchpad. Did you install driver touchpad correct?
    F6 and F8 are designed to work with media player. In the past (WXP) using small plug-in, it was possible to use it for Winamp. I think that something like that doesn't exist anymore.

    You know that's not easy to say to install this or that and everything will be OK. The feature keys FN is where several things work together.

    Please check the download page of Toshiba on http://www.toshiba.eu/innovation/download_drivers_bios.jsp and install all necessary drivers, tools and utilities for Win8.1.

  • Keyboard does not work properly

    Hello

    I had trouble getting my laptop satellite to initialize. Recovery disks & pressing F keys weren't working so I decided to open the laptop to see if there are any loose connections. To my surprise, the laptop seems to work again once I had the USB keys and put back them in! Unfortunately, before that I did, I opened the keyboard and peeked inside.

    When I booted up and tried to use the keyboard keys half of their work and the other half seem to think that they represent two other keys for example if I type the letter 'E' I get '3' and '-' as a whole. After 5-10 minutes the entire keyboard will become totally unresponsive until I restart again. Of course, I think I've done something here because this problem since I opened the bottom of the keyboard. This could be a hardware failure I have caused or is anyway that this issue can be resolved without replacing anything?

    Thank you very much

    Tom

    Hi Tom

    Theoretically, it might be just a connection lost between the keyboard and the motherboard, but I'm afraid, it can be a serious problem of m.
    Maybe you have damaged the connector of the keyboard cable or something similar, and not the keyboard does not work properly.

    I think the keyboard needs to be replaced to check if only this part is affected

  • "A" key does not work on Equium A60

    Hello

    I bought my Equium A60 for more than a year.

    I cleaned the keyboard about a month ago and now my key will not work properly!

    I had jumped off the top plastic part off and blew out the dirt and the thing below rubber came out! It normally covers the sensor, it a little attached to it and presses down on it, so that's what makes the letter arrived on the screen! I put on top of the sensor and covered with plastic bits, but it won't work unless I press and press about 60 times! This is not very practical when you try to type fast!

    Could someone help me please! I don't know what to do.

    And A is that you use a lot, so I can't avoid it!
    Its only the key has, so I don't really want to buy a whole new keyboard, although I would do it as a last resort a little to solve this problem. But even in this case, the rubber part does not come with keyboards? !! I would have thought that isn't that high woth plastic letters on? Will it get a technician, paste it on?

    Help, please!

    Thanks in advance...

    Hi nicola,.

    I can't give you precisely answer how to solve your problem.
    It seems that you will need a full keyboard.
    As far as I know it is possible to also buy only the key caps, but I do not think that a replacement of the key CAP will help you.
    In my opinion, you should ask the Toshiba service partner in your country. Maybe the technician may be able to deal with this issue without replacement of keyboard.
    If this isn't the case, then I guess you need a new keyboard. Don't be afraid, that's not very expensive.
    But as I said at the beginning to seek advice before you buy and replace something.

    Hey Jake,

    Follow these methods.

    Method 1: Follow these steps:

    (a) restart your computer if you have not already done so. There is always the possibility that the error Code 31 that you see was caused by a temporary problem with Device Manager. If so, a simple reboot can solve the Code 31.

    (b) have you install a device or a change in the Device Manager, just as the Code 31 error appeared? If so, it is very possible that the modification caused the Code 31 error.

    (c) cancel the change if you can restart the computer and then check again the error Code 31. Depending on the changes, some solutions may include:

    Remove or reconfigure newly installed unit.

    Restore a version prior to updating the driver.

    Use system restore to undo the Device Manager recent related changes.

    http://Windows.Microsoft.com/en-us/Windows-Vista/system-restore-frequently-asked-questions

    (d) to remove the registry values filters upper and lower. A common cause of errors in Code 31 is the corruption of two registry values in the class of the CD-ROM/DVD-ROM drive registry key.

    Note: This section, method, or task contains steps that tell you how to modify the registry. However, serious problems can occur if you modify the registry incorrectly. Therefore, make sure that you proceed with caution. For added protection, back up the registry before you edit it. Then you can restore the registry if a problem occurs.

    Vista and Windows 7 updated drivers love then here's how update the most important.

    This is my generic how updates of appropriate driver:

    This utility, it is easy see which versions are loaded:

    -Free - DriverView utility displays the list of all device drivers currently loaded on your system.
    For each driver in the list, additional useful information is displayed: load address of the driver,
    Description, version, product name, company that created the driver and more.
    http://www.NirSoft.NET/utils/DriverView.html

    For drivers, visit manufacturer of emergency system and of the manufacturer of the device that are the most common.
    Control Panel - device - Graphics Manager - note the brand and complete model
    your video card - double - tab of the driver - write version information. Now, click on update
    Driver (this can do nothing as MS is far behind the certification of drivers) - then right-click.
    Uninstall - REBOOT it will refresh the driver stack.

    Repeat this for network - card (NIC), Wifi network, sound, mouse, and keyboard if 3rd party
    with their own software and drivers and all other main drivers that you have.

    Now in the system manufacturer (Dell, HP, Toshiba as examples) site (in a restaurant), peripheral
    Site of the manufacturer (Realtek, Intel, Nvidia, ATI, for example) and get their latest versions. (Look for
    BIOS, Chipset and software updates on the site of the manufacturer of the system here.)

    Download - SAVE - go to where you put them - right click - RUN AD ADMIN - REBOOT after
    each installation.

    Always check in the Device Manager - drivers tab to be sure the version you actually install
    presents itself. This is because some restore drivers before the most recent is installed (sound card drivers
    in particular that) so to install a driver - reboot - check that it is installed and repeat as
    necessary.

    Repeat to the manufacturers - BTW in the DO NOT RUN THEIR SCANNER device - check
    manually by model.

    Look at the sites of the manufacturer for drivers - and the manufacturer of the device manually.
