If the laptop display does not show icons on the desktop and an external monitor does not display then the Graphics Adapter has failed. There is one thing to try and that is to boot up with the external monitor connected and try the keyboard key that sends video to the external monitor.

If that test fails then you need to consider the costs of repair vs cost of buying another laptop. The hard drive should still be good and can be connected with an external adapter to copy data to another computer
