Hi Adam, thanks for your reply! I tried that already. Nothing happens when I press the power button with the battery unpluged. I checked the chargers voltage on the board and it´s ok, I have the 16.5v on both pins (2 and 4). It start’s ok bypassing smc.
If I unplug the battery, plug in the magsafe and then plug the battery again the fans automatically spin for 1 sec and then turn off. The “Restart automatically after a power failure” option on the Energy saver is unchecked. I found this doing some research (, maybe that’s the problem? It seems strange to me since that didn’t happend when the gpu crashed.
