I should've been a little more specific.

When I said hardware switch I meant a physical toggle switch near the left-front or left side of the chassis. Those are more common than aggregate function keys seen on the 1440. I am well aware of the wifi toggle key and pressing that didn't help anything.

Ultimately I decided to just do a factory restore. I ran out of time to work on it and went with the Windows fix-all. Thanks for your suggestions.
