    I was curious whether this also happens with Dell Vostro 3550 and seems not:

    Now, after doing once Fn+F2 to disable the device(s):

    # rfkill list
    0: dell-wifi: Wireless LAN
    Soft blocked: yes
    Hard blocked: yes
    1: dell-bluetooth: Bluetooth
    Soft blocked: yes
    Hard blocked: yes
    2: phy0: Wireless LAN
    Soft blocked: no
    Hard blocked: yes
    #

    Another press of Fn+F2 enables both at once:

    # rfkill list
    0: dell-wifi: Wireless LAN
    Soft blocked: no
    Hard blocked: no
    1: dell-bluetooth: Bluetooth
    Soft blocked: no
    Hard blocked: no
    2: phy0: Wireless LAN
    Soft blocked: no
    Hard blocked: no
    4: hci0: Bluetooth
    Soft blocked: no
    Hard blocked: no
    #

    BIOS A09 here, linux-3.4-rc7.


    Just do not know why I still get those "Unknown key pressed" messages:

    [ 2652.048353] atkbd serio0: Unknown key pressed (translated set 2, code 0x88 on isa0060/serio0).
    [ 2652.048363] atkbd serio0: Use 'setkeycodes e008 <keycode>' to make it known.
    [ 2652.103556] iwlwifi 0000:09:00.0: RF_KILL bit toggled to disable radio.
    ...cut...
