Hi I've had my MBP a little over a year (No Apple Care (ouch)) anyways I left it to get a drink yesterday and came back to find it had gone to sleep (sleep timer on 5 minutes) so I pressed any buttons moved the mouse and nothing. I turned the computer off by holding down the power button and back on and nothing. Since this happened I have not been able to get the screen to show anything yet i can hear the sound tone when lowering and uppering the volume. I have also tried connecting an external monitor to it and nothing. Would this be the logic board or the GPU and how much to replace the suspicious part? I was going to get a mac pro 2009 model anyways and I was thinking about just leaving the MPB alone and not bothering spending anymore money on it because it is nothing but trouble, the only thing is I have some important files on the hdd and I have tried target disc mode to another computer using Firewire cable and couldn't get that to work either. Is it possible to take the hdd and put it in a PC or something and grab those files i need?
