On this M400 laptop I found another interesting scenario.
   >The VGA is attached before powering on. After the system is powered on, the system will select the VGA as the primary display device in BIOS phase. Then I use the hotkey of "Fn+F5" to switch the primary display device from VGA to LVDS panel. And after the system is booted, the VGA can't work well, neither.
    If it can display on both VGA and LVDS in BIOS phase, the VGA monitor can work well as expected.

Thanks.
