My Macbook Pro 15", retina display, early 2013 suddenly doesn't turn on anymore. I can hear the boot up sound, but the display doesn't turn on and the Apple Logo doesn't show up.

I thought that the graphics chip could be broken, but it's not only the display that doesn't work. The Caps Lock LED isn't lighting up as well.

It has about 80% charge and the power cable also works. I tried to use an external monitor but it didn't make a difference. I also tried SMC reset and all those things, without success.

Any ideas what the defect could be?

  • Can you attach an external display? Does the diagnostic mode work (press D during boot)? If not, most likely the logic board is fried and you'll need to have that replaced. – slhck Jun 25 '18 at 8:18
  • Thanks for the tip. I tried this and it didn't work, so I gave the macbook to the apple support. – Stefan Jul 17 '18 at 13:26
