.Sh HISTORY
The
.Nm
device driver appeared in
.Nx 6.0 .
.Sh AUTHORS
.An Jukka Ruohonen
.Aq jruohonen@iki.fi
wrote the actual
.Nm
as well as
.Sy wmidell
and
.Sy wmihp .
The
.Sy wmihp
was based on the earlier work done by
.An Michael Gmelin
.Aq freebsd@grem.de
for
.Fx .
.Sh CAVEATS
While
.Tn WMI
should provide a certain degree of portability across laptop
models from a particular vendor, there is no guarantee that the mappings
are functional in all models.
.Pp
The
.Sy wmihp
driver conflicts with
.Xr hpqlb 4 .
