All PCs and many electronic 'gadgets' such as PDAs have 'real time' clocks in them that obviously run all the time even when the main device is 'switched off' - they have to in order to keep accurate time ! The activity of these 'clocks' would be detectable by a very sensitive receiver tuned to the correct frequency. The signals would be at a very low level and would be further attenuated by the screening effect of the metal car boot.

As an electronic engineer I think that this COULD work !

If anyone is interested I could build a 'jammer' to defeat such a system but easy thing is not to leave your laptop in your car ?

P.S This 'wireless' technique is used to calibrate electronic wrist watches !!

Sounds interesting. I don't know about other people but I would be interested to see if the jammer works.
