Bought this computer and from day one we could not get it to change the time zone from Pacific Time Zone.  I did everything from adjust in settings, Registry edit and even tried to change it in the bios.  Whoever had this before locked everything down.  Less than 6 months in and it stopped allowing internet access.  Do not buy a refurbished computer as you have no idea who or what has tinkered with it and what they put on it.
