My MBP won’t start anymore. All I hear is the optical drive startup sound. When it started it did this a few and then it would boot but now it doesn’t start at all. A couple of times that it did start I was able to log in and then it would crash/restart again. https://youtu.be/UpG_9SUOA7E
Let’s go for a spontaneous reboot. Unplug the mag-safe, disconnect the battery from the logic board, press and hold the power button for 10 seconds. Reconnect the battery then the mag-safe. Let us know if it boots.
