I noticed that this laptop has both HDMI and VGA out. Have you tried connecting an external monitor to deterime whether it is the display adapter or the actual screen that is dead? If it is just the LCD; a replacement will run you $120-$160.
If you have the laptop, but not the charger; you can find replacements all over the place. One place I use (and highly recommend) for Dell parts is http://parts-people.com (http://www.parts-people.com/index.php?action=category&id=... if you want a charger for your laptop). If it is another issue; could you please post additional details?
