I don't have such a file in the system, but here's some stuff I grepped
from /var/log/messages:

One thing which puzzles me here is the acer-wmi driver. As you might
guess from the host name, the laptop is a Lenovo Ideapad S12 with Intel
and Broadcom hardware. Often driver names are different from hardware
brand names, but still "acer" doesn't really seem to fit the picture
here.
