Know of a good program to lock your laptop if it gets stolen?

[buckshotdots]

Hello, does anyone recommend a certain kind of lock for my laptop- I am thinking password protected program instead of an actual lock but open to anything. I would be lost/screwed if it was stolen/lost. Any ideas would be appreciated...

thanks, Gary.
