Hello. I want a laptop, that can be prevented(by hardware) from establishing any wireless connection with physical switch. So that I can be sure that it does not have connection if the switch is in given position and it is not connected with wires, irrespective of software that the computer is running. Even better if I can check it myself by looking at electric circuit in the computer. By wireless connection I mean wifi, bluetooth, infrared or any other type of wireless connection. Can you recommend some laptop models to me?
