MacBook Pro completely unresponsive after windows 10 dual boot

[PollenKidney]

Hi, after successfully going through boot camp and installing windows 10 on my MacBook Pro (13 inch late 2013 256GB, macOS Sierra public beta) I turned down the brightness of the display to zero and went to bed (leaving windows on with the display off). When I woke up the next morning, I tried to turn the screen on but nothing happened. I then thought the computer might have turned off, so I pressed the power button. Again, nothing happened. At this point I was freaking out, so I tried a hard reboot with the power button. To my relief, my MacBook started rebooting into macOS. However, the computer soon got stuck on the very last portion of the loading bar and would not do anything. I then tried going into single user mode to try to repair disk permissions. That went without a hick, but rebooting led to the same issue. I tried safe mode, but that had the same problem. I then gave up and tried to boot into windows. That worked, and this time I closed the screen when I went to bed in order to try and figure out what had happened the next day. This time when I woke up, the computer screen was dead and the computer itself completely unresponsive. I checked the power cable to make sure the battery was charged, which itwas. Then I tried every hard reboot method under the sun, and none of them worked. The computer just won't do anything.

List of things I have tried:

Cmd+control+power

Cmd+s+power

Cmd+r+power

Cmd+option+p+r+power

Shift+power

Unplugging power and all of the above

Unplugging power, Holding the power button for ten seconds, then releasing the power button as I plug in the power cable.

Does anyone have any suggestions as to how to start my computer?

Note: the power cable shows that it is charging the computer when I plug it in.

Is there an apple store near you? Do you have apple care?

I really can't think of anything else that you havn't done. They may need to flash it with a new image

I live in outer Shanghai, and the only Apple Store is on the other side of town. There's a retailer near me, but when I asked them they said they didn't offer the correct services. I guess I'll just have to set an appointment and drive out to the Apple Store.

Thanks for the advice!

Sierra is a beta release that is unlikely to be currently fully compatible with boot camp. You are always advised to install it on a separate partition or a non essential computer for exactly these reasons.


Putting El Capitan back on is the only sensible answer here.

I agree, but I don't know how the thread starter would be able to do so if it won't even turn on.

If you can get the computer to power back up, you can use a USB Drive with El Capitan on it to do a full restore. Anyone with a mac can make one - if you have any friends who have a mac you can try that. But again, it needs to power on to do this.
