Many times I heard that thieves have device to check/detect if there's any electrical/electronic devices on car. But I've never seen such a device before. I wonder if such device really exist or it's just a pure speculation?
There are so many electronic/electrical devices in a car: Radio, battery, ECU, etc and I do not see how the so call detector can differentiate these devices base on the wave (if it really can be picked up).
Yeah, plus the fact that no such device has been seized by police anywhere in the world before...
I think the thieves are expert scouts, ie. they stake around parking lots observing the interior of a car and try to notice any thing that might tell that the owner is an IT worker and/or has a high probability of having a laptop in the car. Anyways, a laptop bag on a seat is a no-brainer... or, maybe they might stake out near a place where IT workers work at, and then it's easy to identify which cars parked there has an owner that carries around a laptop.
If there is such a detection device, I'm not sure if it is picking up signals from Li-ion batteries. That's the only component that a laptop has freakin' lots of, compared to other electronics that's natively in a car.
