Macbook Pro 2018 Touchbar Model won't turn on (Black Screen)
Hey Guys,
i just got a Macbook Pro 2018, with Touchbar from one of my relatives to repair.
The first Time i plugged in the USB C Cable it turned on fine, but after i started the Update to OSX Big Sur, it suddenly turned off after the Update (the Update Bar was full) and the fans were going to full speed for a moment, so i thought, that it just needed some time and left it for like 10 minutes. After i came back, it had still a blackscreen. So i removed the backplate just to see, that the fans are still spinning. i removed the battery connector, and waited like 1 minute. i reconnected it and plugged in the power cord. it showed the Apple Logo and did the chime, but in the boot sequence it crashed like half way in, then the fans again were spinning for full speed for a moment, and the display gone black again, now when i repeat this process nothing happens.
Maybe someone knows what to do?
And sorry for my English, i am from Germany, and i dont write it that often
