Hi....this is my first post on here so please be gentle........ I have a Dell Inspiron 600m which I have been using for just over 2 years with virtually no problems....but about a week ago I was on a plane playing solitaire and my screen showed a few green, blue, and red squares and then went black. It sounded like it was still running, though. I turned it off and tried again a few minutes later, and it was still black but sometimes if I moved the screen back and forth I would get a brief view of my desktop. I hooked it up to an external monitor, and everything is working fine. I have spoken with several places, and I get different answers every time so I was hoping to gain some insight via this forum. Any help you can offer is greatly appreciated, thanks so much for your time!! -Kristen!
