My daughter has my Dell XPS 15Z Laptop Windows 7 with her as she is studying abroad in the Dominican Republic for college credits. Her computer was running plugged in with the start up screen icon when it went digital and lost the screen. the fan runs faster. she can turn it off with one click. starts up same problem. It is really hot there now and the laptop was on the bed. I told her to hold a flashlight up to the screen to see if she can see the icons but she can't (Had an inverter problem before on another laptop) nothing works that she can see. like the CAPS button does not light but she can hear the fan. My first thought is its hot and wet. I have limited phone with her but what can I do?
