Here's a demo video of Intel's Anti-Theft Technology feature released in Fall 2008:
Intel AT-p includes hardware-based detection mechanisms that can recognize potential loss or theft. When a suspicious situation is identified, Intel AT-p will activate according to your IT policy in "theft mode". As a completely flexible engine, Intel AT-p allows you to specify which detection mechanism should be used to assert theft mode and what actions to take. When the notebook returns to its rightful owner, it can be reactivated to full functionality via a pre-configured pass phrase or token generated by the IT console.
