Thanks Pat, there's only the "lighthouse" button, that I'm interpreting
as wifi on/off button. Other than that there doesn't seem to be any
"bluetooth" or related button.

As for:
# lsusb

Bus 001 Device 003: ID 138a:0018 Validity Sensors, Inc.
Bus 001 Device 004: ID 064e:e258 Suyin Corp.

"Validity Sensors" seems to be the fingerprint reader and "Suyin Corp."
seems to be the laptop camera.

I wrote Matthew Garrett the hp_wmi author, but haven heard back. I'm not
sure, maybe I shouldn't contact him directly or maybe he's just busy or
on holidays currently.

If anybody can point out to me what direction to take from here I'd be
very glad.

Thanks,
