The "black screen of death" is usually very easy to repair on a laptop. First turn your computer off by pressing and holding down the start button. Next unplug the computer and then remove the battery. Press and hold down the start button for about 60 seconds. Release the button and plug in the computer. Press the start button and the display should return. Replace the battery. If this does not work, try it again up to four times. No results usually indicates a bad mother board. Hope this helps.
