MacBook Pro 2011 15" won't turn on, sleeping light flashes once.
My Macbook Pro won't turn on since I tried to use a mini display to HDMI adapter. Now when I press the power button, I hear the hardisk and the sleeping light flashes one time, and if I wait 3 minutes, the screen is white for 10 seconds, and the Macbook reboot; When I close the Macbook powered up the sleeping light stays turned on.
If someone can help me because I use this Macbook for my studies.
Is dit een goede vraag?
