If you switch it off using the switch next to the power on/off switch then that was what I was referring to as the hardware switch as opposed to using the Fn function key combination.

I know you say you don't wish to remove the wireless card yourself but it looks easier than my Amilo L7300 to do.





It looks as if you just need to take off the bottom cover and if you look at the board below the HDD and to the right of the memory that looks like your wireless card. You can see what seems to be 2 RF connectors in the top left.

edit: I should have added that if you do decide to remove it, unplug your power supply (Battery Charger) and remove your battery first.

edit2: Looking on the FCC site the 8180 cards are pretty new, is your Laptop not still under warranty or has it just expired?
