    My NB200-134 of FN keys does not work after upgrade from Windows 7 starter to Windows 7 ultimate. I tried to install all the drivers found on the Web from Toshiba website for my lappy but it still does not work.

    Hi asalamk,

    The FN keys are controlled by value added and Flash Cards Support utility package. I think you forgot to install these tools

  • X 220 microphone does not work after Windows 10

    Firstly, as far as I know, my upgrade to Windows 10 has worked very well and I love the new OS. The only problem I have is that my microphone does not work. It shows it as being installed and working properly, but I can't use it anywhere in the system. The driver is the Contexant 20672 SmartAudio HD.

    When I go to "Set up a microphone" is said "the wizard could not start. Make sure that your hardware is working properly and check your audio configuration in the control panel to control Audio devices and sound themes. »

    My microphone is turned on and the volume is growing.

    Any ideas?

    The same problem. I deleted the folder drivers\win\audio and loaded the drivers of Windows 7 instead of Windows 10 drivers from Lenovo site. Solved.
