My MacBook experiences boot up problem.
A normal MacBook could startup properly after pressing the power button and a chime sound would be heard.
But my MacBook (2014 Mid MacBook Pro with Nvidia graphic card) is a different story. After I pressed the power button, I would hear 2 chime sound and the screen is not turning on. I have to force shut down and reboot again. Then everything seems OK again.
This is really frustrating, it happens every time I shut down or sleep my device.
