Responder a:Boot Up Problem - Black ScreenThe exact thing has happened to me . When I changed the Hdd on an SSD I put a poor quality adhesive and the screen peeled off. The same symptoms, screen totally off, fan at high speed and the system runs slow. I put an external monitor and it works very slow. Both connectors are apparently not damaged. Although this is surely the problem because of Dan's brilliant diagnosis, it fits into the description of the problem. It would be nice to know if Mr. Ron Goldman solved the problem by changing the LCD flex.
