When I was shopping for my current Thinkpad T61 I was given to understand that the switch on the front of the case physically turned the power to the bluetooth and wireless devices on or off. I have never inspected the wiring diagrams for the T61 to see if this is really true. But if a business traveler turns off the switch and then powers on the laptop during a flight, and as a result of the radios not really being turned off the plane crashes, the bill that Lenovo will receive will not be trivial. I feel comfortable in assuming that corporations quake in fear of the unbounded greed of ambulance chasing attorneys. As for Linux software, I don't know. I do know that if I flick the switch off while running Jaunty I instantly lose my bluetooth mouse and my wireless connectivity via the internal Intel 4965agn. _______________________________________________ PLUG mailing list [email protected] http://lists.pdxlinux.org/mailman/listinfo/plug
