I have a macbook pro that i got, the issue is that when you press the power button nothing happens, no fans, no hard drive spin up, no sound, like it has no pwoer, however, the LED on the MagSafe adapter turns amber / green when plugin, the battery shows all All lights green when pressing the test button. I am trying to figure out if this means its something on the logic board :( Serial Number Information W804840LAGW
