Some of the Fn keys on my Lenovo Thinkpad T460s do absolutely nothing (the ones assigned to F4 and F7-F12 to be specific), the others work as intended.
Now I wouldn't expect them to work out of the box (since some of them normally do a specific Windows function) but I would at least expect them to return a scancode when pressed, however nothing happens instead.
Though apparently they don't work natively on Windows either, I had to install software from the Lenovo drivers page (I think it was the settings dependency package) for these buttons to be usable.
Nothing is mentioned on the wiki page for this laptop regarding this issue, perhaps someone with the same model can report if these buttons work on his/her system?

It sounds like running below and hitting a key returns nothing. I have seen this happen on laptops and you can check a few more places.
sudo showkey -sCan you try hitting the key and checking dmesg?
look for something like this
atkbd serio0: Unknown key released (translated set 2, code 0xbf on isa0060/serio0).
atkbd serio0: Use 'setkeycodes e03f <keycode>' to make it known.Also run evtest and post results
sudo evtestOffline
Output of "dmesg | grep serio" (after trying the fn keys in "sudo showkey -s"):

Lets try running against the AT keyboard. Run the following and then hit the key and see if you get feedback
sudo evtest /dev/input/event4Offline
Well normal keys show up there when I press them, as for the problematic Fn keys, again nothing (as well as the Brightness keys which is weird because they do work)

Though that could have been a different issue since more recent posts about this indicate the same issue that I'm having: http://article.gmane.org/gmane.linux.ac … devel/3995
Its not really clear to me what the current status of this issue is, apparently there is a patch for it but its not yet in upstream? Either way, I guess I'll just have to wait for an update and I'll mark this as solved for the time being (might be useful to mention this in the wiki though).

yep I was curious if you had the module thinkpad_acpi as there is an active kernel bug: https://bugzilla.kernel.org/show_bug.cgi?id=114731
