gps tracking device can cost a fortune, I suggest you get a smartphone and install a gps tracker app like mobilespy on it, the solution is much cheaper, more info check Monitoring-softwares.com

Hi so it needs a small radio transmitter and a receiver with a signal meter so you can see where it is going so some kind of radar system that is the expensive bit.

I have a Thinkpad also and it did the same thing. Never could get it to work again. I just got a wireless mouse from MS and use that. It works fine and you can use it anywhere on almost any surface.
