Plug in something (preferably a external HDD or an external DVD drive), press the power button. If it reacts, it means the GPU or the display could be shot. Also you should try to use the Displayport to DVI or whatever converter it came with to connect it to an external display and see if that works. If it doesn't then there really isn't much to help you with, and either way you'll need to send it in to dell to replace whatever is broken. I'm going to guess its the motherboard though. One way you can get the data out is to get a usata to USB (which I can't find.. so I'm going to say its safe to assume it doesn't exist) and take out the SSD and pull the data out. Otherwise you can't get the data out, i'm afraid. The lesson from this story is to remember to BACK UP!!!! Backing up is extremely important for unfortunate events such as this.
