Shine a flashlight on the dark screen to see if you barely
see the icons on the desktop. If so, then the LCD Inverter is bad.
Plug in an external monitor and see if the display shows up on it. It can be any kind of monitor even the old big fat crt monitors as long as it has a vga cable to connect to your computer's vga port. If so that proves your video card is ok. The video will show on most systems when you reboot without you having to do anything. Some systems will require you to hit the FN (Function key) + F1 thru F12. Hold down the FN key then hit the correct key for displaying on the monitor (F1 thru F12). The correct key will normally have CRT/LCD on it or it will have the icon of a display.
If you see no icons by shinning a flash light and the external monitor works, then your screen is bad. If you see no icons by shinning the flash light and nothing shows on the external monitor, then most likely your video card is bad.
The lcd inverter can be purchased on ebay for less than $15. It is located at the bottom of the lcd screen. You'll have to remove the plastic strip that is around the lcd screen by removing the plastic or rubber bumpers that have screws under them. Normally there will be bumpers at each corner and maybe along the insides on the plastic strip. Remove the bumpers, the screws and pry the plastic strip off with a little force with your fingers. You will then see the lcd inverter at the bottom of the lcd screen.
Just put your computer's name and model in the ebay search followed by lcd inverter.
Actually it looks like your laptop uses the LED screen instead of LCD so it will not have the LCD Inverter. You will have to purchase a new screen. I found the one below on ebay.
