hello, my laptop starts up except that this shows does not work on the internal screen to force seen on the internal one you have to connect a vga cable linked to an external lit screen then you just have to unplug it to recover the display internally.
When you have the external monitor connected, look at the display settings. If the screen is MIRRORED, then change it to EXTEND. If the screen is mirrored, then Windows could be waiting until the second screen is connected so that it CAN mirror the image to both screens.
