Two things you can do – to recover your lappy and protect your data.
If you are concerned that thieves can steal your laptop during a trip you can implement GPS tracking:
Encrypt the whole harddisk using TryCrypt: http://www.truecrypt.org/
This is because software-only encryptions have been found to be very unreliable if your attackers are skillful programmers.
Laptops get stolen all over the world and the main problem is that we often trust too much on key locks. Any physical lock or key can be broken. In a similary way, biometric locks such as fingerprints and eye-scans can be circumvented with special skills and devices. So GPS tracking promises an extra security layer.
