Chosen Solution
Got the good ol’ black screen upon boot. Tried all the common reset key shortcuts, tried removing the battery, tried different RAM configs, tried a different power supply, even tried the trick where you disconnect the fan, also waited for the battery to go dead - nothing. how should I go about with the diagnosis? where do I begin? what are some parts that are likely to be related to this problem?
Disconnect the battery and the MagSafe. Press the power button for 10 seconds. Reconnect the MagSafe and if the Logic Board is good you should get a spontaneous reboot.
