Brightness of yoga 2 13 keys does not: it was TeamViewer Monitor driver

Hello, I have two Yoga 2 13 - I think that the model 59403750. Both have the same characteristics.

In one of these Yogas - "F11" and "F12" - brightness keys do not work and it is full BRIGHTNESS of 100% all the time. In the other (good) Yoga they seem to work OK - at least I can get the BRIGHTNESS down a few notches.

When I press and hold down the Fn key to get F11 or F12 to work the * seem * to do what F11 or F12 would normally - for example in a word processor or browser. It seems maybe just the function of BRIGHTNESS of these keys do not work.

Lenovo has calimed that this isn't a hardware problem and they are not liable under the guarantee.

I've done a little reading some time previously and saw something similar which was perhaps fixed by installing updated video drivers. Well, that has not worked - from the a few months ago. At the point where I've also updated the BIOS - again no luck.

Any ideas /inputs that you may have are appreciated. Thank you.

  • Laptop HP 15-R203tx: brightness (f2 and f3) function keys does NOT work

    Model - HP laptop laptop 15-R203tx

    OS - Windows 8.1 Pro 64-Bit

    Graphics - Intel HD 5500 integrated

    Dedicated NVIDIA GeForce 820 M

    I updated the drivers for my also well-integrated dedicated graphics card but still my function keys f2 and f3 for brightness control does not work although all other keys work.

    This PC comes with the BACK, but I started it with 8.1 Windows Pro 64-bit.

    Hello

    Well that does not explain why your f2/f3 keys do not work as you have only the Microsoft base driver installed - if the Intel driver has already been installed Ok, this may indicate a hardware problem.

    What happens if you try to install the Intel HD 5500 driver directly from Intel - it's the 2nd file in the list on the following link.

    https://Downloadcenter.Intel.com/search?keyword=Intel%C2%AE+HD+graphics+5500+for+5th+generation+Intel%C2%AE+core%E2%84%A2+processors

    If it installs Ok, reboot the laptop and let Windows fully load for a few minutes before checking it in.

  • Windows 8 Pro key does not work after changing HARD drive

    I had bought a Lenovo machine without installation of the OS and installed a Windows 8 Pro (and not an upgrade).

    After activation ( laptop settings-> activate Windows ) and control, the copy of Windows has been properly activated.

    The machine worked fine for 7 months before the hard drive crashed and I had to replace it. (Without recovery).

    On installation the same Windows 8 Pro on the new HARD drive again, it shows " this key did not work." "If please check and try again or try a different key"

    Please suggest a solution to this problem.

    If my copy of Windows would have been an upgrade version, it would not have worked the first time.

    Have you bought a copy of manufacturer of OEM of Windows 8 Pro system? Because there was no full version boxes retail copies of Windows 8 Pro. The following work around to try to see if it works with your copy and then try the phone activation;

    http://www.eightforums.com/tutorials/13375-clean-install-Windows-8-upgrade.html

    Activation of the phone:

    1. press the Windows key + X , and then clickrun, and then type: slui.exe 4


    2. then press the ENTER"" key.

    3. Select your "country" in the list.

    4. choose the option "activate phone".

    5. stay on the phone (do not select/press all options) and wait for a person to help you with the activation.

    6. explain your problem clearly to the support person.

  • Satellite A200-10N (PSAE3): Fn key does not work after upgrade to vista any time

    After upgrading Vista-Home - Premium--> Vista Ultimate shortcut with the fn keys does not work, for example Fn + F6/7 (brightness).

    New value pack installation has not been successful.
    Moreover, after upgrading the drive to DVD from Toshiba is default, too.
    Who can help?

    I didn't try any update on my A200 but you can try to follow: install Vista using recovery media delivered. When Vista starts for the first time go in Panel and you can find Add/Remove Programs option. Remove all the stuff designed by Toshiba.

    When we remove everything, making Vista upgrade. After finishing Vista upgrade install all the stuff of Toshiba designed by order of specific facilities starting with added value package. Check please the download page if all of these tools and utilities are available.

    As far as I know all the tools and utilities are designed as universal tools and I can't imagine that there is a difference between the version of Vista ultimate or premium tools.

    DVD player is part of the image of the installations only and I can imagine that upgrade installation has changed something, but the upgrade procedure is responsible for this. I don't see any connection to Toshiba.

    As I said I don't have a CD to upgrade, but if I find one I'll try to test it on my Vista (Premium) preinstalled A200-1CR.

    Bye and I hope that you report your experiences with the Vista upgrade again.

  • Satellite M70 - 181 - slider and escape key does not

    FN with F10 keys shows no reaction.
    Check all the drivers.
    But cursor and escape keys does not.
    Need help please

    Joe

    As far as I know, FN + F10 or FN + F11 active integrated keyboard and cursor control keys.

    Satellite M70 is a fairly old machine and I do not remember which driver may be responsible for this control. Try to reinstall the Toshiba Accessibility or FN-esse utility. Maybe this will help.

    I had M70 long ago, but I've never used this option.

    Thanks for your help.

    Hey Buddy,

    Have you reinstalled as Flash Cards Support utility? The FN keys to both tool and value added package.

    Again, you should check the site Web of Toshiba Flash Cards Support utility:
    http://EU.computers.Toshiba-Europe.com > support & downloads

    So uninstall old utility Support Flash Cards and then install the latest version of it.

    Check this box!

  • Portege R700 - Touch Pad, ecoUtility and presentation of the key does not

    Hello

    I got a Portege R700 with Windows 7 64 bit.
    This machine starts very slowly after the log in user mode only.
    The system is waiting for 1 to 2 Minutes before you can work. In administrator mode erverything is fine and fast.

    Thus our directors thought it might be the Toshiba Software and a lot has been disabled or uninstalled.
    Because this did not help and because I thought that it migt be cause of Kaspersky, I started to reinstalled and update the software from Toshiba. Most of it works now. Shortcut keys does not work, then I start TfcRst.exe via autostart now, even he would somehow it would be better in 'systemecommencent '.

    But still some keys do not work. The Tablet touch power switch, just above the touch pad does not work.
    The Fn F9 works. And the two keys to the right upper corner (ecoUtility/off button and the presentation-Key) do not work. In all three major, I get a pop up saying "this function not taken in charge.

    Anyone has any idea of this?

    Thank you

    Hello

    Why you n t try to restore the operating system back to the same state until the administrator has removed or uninstalled the Toshiba Software?

    Generally speaking the VAP (value added package) controls the multimedia keys.
    Also the FN keys require the VAP and Flash memory card Support utility.

  • FN key does not work on the satellite L745

    yesterday, I uninstall almost all toshiba prog and then my FN key does not work!
    Please help me this laptop is only a week

    Hello

    Install the VAP (value added package) and reboot the laptop.

    Then install the Support Flash Card utility and reboot once more.
    Then test the Fn keys.

    The buttons are controlled by Flash cards, so you should be able to use the buttons after a new installation of this app.
