I have a T16 and ran into that issue. It may be that BIOS changes have
broken things, but I found that, by default, the F keys control volume,
screen brightness, and many other things. I can use Fn+F[1-12] to perform
traditional function key functions. I found that bios has an option to make
the traditional functions the default which is how I am running today and
have since shortly after I purchased the computer. One I set that BIOS
option, everything worked "properly". I now use Fn+F[1-12] to adjust volume
and screen brightness. I hope to get mute to work, but I need to figure out
which event is set when Fn+F1 is pressed to write trivial devd support for
it.

BTW, if you have not found it, Fn+K is screen lock. Most everything on my
T16 now works with FreeBSD CURRENT.
