This should not affect files and is worth a try.

I have a black screen on Dell Studio 1737 laptop.When I was connecting my VGA cable from my TV to my laptop (both were on big mistake) anyway there was a small spark from the cable connection to the VGA connection on the laptop, and my screen went black and all the media control lights went on and stayed on. (not normal behavior) I turned off the laptop with the on/off switch, waited a few minutes and turned the switch back on. The media control lights came on briefly just like they normally do,but then there was nothing no light on the on/off switch and a black screen. I am hoping that someone might have a guess as to which path from the VGA connection that the short may have taken. Thank You in advance for any ideas that might help. Ron
