When I press Fn + Space, the OSD message appears correctly, and the quick settings menu shows the keyboard button with Off / Low / High options. Howe= ver, the High setting doesn=E2=80=99t seem to have any effect. Should this keyboard control button even be visible in this case, or did I = mess something up again? --=20 You may reply to this email to add a comment.
