I think this must be a fairly common way for HP at least to do it. The switch on my HP dv5120us feels like a momentary of some sort, and in windows it turns the radio on and off. However it seems to be a bit confused for linux, if its on, and the led in the hinge is on, then there's a 50% chance the radio is on. Tapping the button in linux turns off the led, but never turns it back on, so I have to tap the button and restart the network, repeat till the led comes on. However, iwconfig and iwlist appear to report that it is functioning when in fact it is not until the magic twanger combo of button taps and network restarts finally manages to enable the led again. In other words, it appears that button status and led status to make it work are a real crap shoot. Communication between the button and the radio certainly seems broken on my lappy. It BTW has a bcm4318 radio in it. -- Cheers, Gene "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
