They must have installed a new keyboard and did other things to it because although it's a refurb, it looks brand new.  No dead pixels either.  Outperforms my new $1000 Lenovo work laptop in all areas except disk which is expected because this unit comes with rotating media which does not matter to my son because he's playing games on it; the Nvidia helps a lot.  This was a great purchase.  Can't beat the price vs. performance ratio.
