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". -- | Jeremy Chadwick jdc@koitsu.org | | UNIX Systems Administrator http://jdc.koitsu.org/ | | Making life hard for others since 1977.
