Jeff Marcom, as per http://download.lenovo.com/express/ddfm.html an update is available for your BIOS (2.58). If you update to this following https://help.ubuntu.com/community/BiosUpdate , does it change anything? If it doesn't, could you please both specify what happened, and just provide the output of the following terminal command:
sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date

Thank you for your understanding.

Title:
  [Lenovo ThinkPad T530] External display does not work through Display
  port or VGA

Status in “linux” package in Ubuntu:
  Incomplete
Status in “linux” source package in Precise:
  Confirmed

Bug description:
  Problem: 
  Connecting a display through the display port does nothing. I can try to press the key combo fn + f7 or trigger the monitor to refresh and the display is still blank on the external monitor.

  udev does not seem to notice the display port connection either.

  Expected result: External display should be mirrored when inserting a
  display port or VGA connection.
