It is readonly, I cannot toggle it. I am not sure how acpi figures it is on and the wifi drive figures the hardware switch is off. I noticed a lenovo notice about a similar problem under windows, and an updated windows driver to fix it, but that is supposed to only apply to waking up after suspend. There are also these guys who solder out the hardware switch. I think that is what I am going to do next: https://forums.lenovo.com/t5/X-Series-ThinkPad-Laptops/X201-Faulty-Hardware-Wireless-Radio-Switch/td-p/1063743# Martin -- %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% Martin Cracauer <cracauer@cons.org> http://www.cons.org/cracauer/
