    Set please BIOS to default settings and restart your notebook.

    The BIOS contains the option called: “Power On Display”
    This option controls the display output while the computer is started.

    I guess it can be set to “LCD Only” or Auto Selected.
    Usually it set to “Auto-Selected”
    If you choose “LCD Only” output image will appear (should) appear on internal display only.
