The issue Warren listed off is specific to the Lenovo T420.  It does not
happen on the T430, nor later models (this is further confirmed by the
last person posting in the thread).  Models prior to the T420 may also
have the same problem (speculative / I do not know for certain).

I interpreted what Warren was saying to mean "yes it works, but some
models of laptops/hardware don't work with it".
