I have a Latitude E5470 on Win 7 x64 that I am not able to use the soft key toggle switch (FN + Prtscr) to turn on or off the wireless connection. This functionality works perfectly in the Win10 laptop, however seems that the driver does not allow or is not functional in the Win7 environment. (In Win10 the airplane mode appears when I toggle the option.)
Have anyone experience this issue or knows of a workaround to resolve this in Win7 ?
Thanks in advance. - Ron
This may sound crazy, but it could be that the Fn mode is default on that laptop. Try just pressing the Prtscr button without pressing Fn and see if that works. I know that I have mine set to default to the Fn mode and I have to press Fn to get the "F" key to work.
