I have a generic compal laptop without such physical button. However, I got this bug. The solution offered in comment #50 fixed it for me. Just prior to this bug manifesting my laptop went into sleep mode it failed to wake up from leaving my touchpad in this disabled state and as described in separate bug Network Manager turned off pretty much making my laptop unusable.
