LoJack For Laptops- New York Times

LoJack for LapTops: "Intel’s newest line of notebook chipsets for 2010 have an extra security feature: They can be ordered remotely to lock up at a below-the-operating-system level, so the laptop will only boot a notice that it’s not available. It can optionally display, say, the owner’s name and email, in case it’s brought into a pawn shop. To turn it back on, it needs an extra-special password that only the user, an IT worker, or Absolute can provide."
