  1. No effect upon pressing and a function key


    I have an ASUS laptop, K52JC, it used to perform certain function when combination of <fn> key and a function key are pressed simultaneously. For example -


    • Pressing <fn> and <F10> simultaneously will mute the sound


    • Pressing <fn> and <F11> simultaneously will decrease the volume


    • Pressing <fn> and <F12> simultaneously will increase the volume, and so forth


    I have its Windows 10 re-installed recently. Everything works fine after the installation, except when combination of <fn> key and a function key are pressed simultaneously, no effect seems to be generated, as the computer does not respond accordingly.


    Please advise how to resolve the above problem.

    :)

    FN key always on

    If you press “Num Lock" (might also be labeled "Num Lk”) (I’ve also seen it labeled “Pad Lock” for numeric Pad) it turns on the blue keys, and inverts the meaning of the “Fn” key – it’s a way to use that embedded numeric keypad without having to hold down the “Fn” key the entire time. To fix it, just find and press the “Num Lock” or “Pad Lock” key again. (Note, sometimes these keys are themselves “Fn” keys, so you may, or may not, need to also hold down the “Fn” key to get the right function.) Often there is an indicator light associated with the setting.

  3. New laptop FN keys not working [Solved]

    Ummm, that is normal - depending on the function you are doing (assuming I understand what you are saying).

    On a notebook, the Fn key is like a shift key that switches in a different set of functions for the F-Keys.

    For example, in Windows pressing the F5 key typically refreshes the display. In File Explorer, it will refresh the displayed files. In a browser, it will refresh (reload) the webpage. But pressing Fn + F5 does something different, depending on your notebook. On my Toshiba notebook, if I hold down the Fn key and press F5, it switches the video output of my notebook between the notebook monitor, a connected external monitor, or both.

    New laptop FN keys not working [Solved]

    Exactly what I was used to do, pressing the FN key with an F key but that didn't work....
    If I press the FN key I get f1 f2 f3 and so on.

    It was just the other way around, but I figured it out now.*Smile No effect upon pressing <fn> and a function key :)
