Chosen Solution
My MacBook Pro does not boot up, if you press the power button you get nothing at all, MagSafe light is on green no other colour but green, I have disassembled it guess what nothing happened.
Removed the mag-safe adapter, then disconnect the battery from the logic board. Press and hold the power on button for ten seconds. Reconnect the battery, then the mag-safe. You should get a spontaneous re-boot.
