I had two of these and both times the gpu went on it, they run too hot so the gpu either fries or needs reballing. It's possible sometimes to rescue them by reflowing the gpu with a heat gun, this melts the solder again and fixes any dry joints. To get your info off the laptop you can try plugging it into a tv or monitor with a VGA / monitor cable, as a lot of the time you can still get a picture on the monitor when you can't on the laptop screen, I know this was the case with both of mine that died.
