My Dell Inspiron laptop (runs Vista) was working fine this morning, then I turned it off. When I tried to turn it back on, some lights came on and the welcome tones, but no screen at all. I've taken the battery in and out as this was the only thing I knew to try. Any ideas?

DennyGirl at a loss!

you might have accidentally switched to using a external monitor...try holding down your function key and pressing the key that has the picture of a monitor on it. I think dell is f5 but not sure.

Thanks so much! I didn't think anyone was ever going to have an idea. Unfortunately I can't try your suggestion yet as the picture mysteriously came back on, but I am confident that I'll have more problems with it. I'll be sure to let you know if it works!
