Hi there.
I have Macbook Pro 16" 2019, model number A2141, motherboard number 820-01700. I have some problem with dedicated graphic card. When Macbook switches to dedicated GPU it is getting instantly hot and starts to show glitches on screen, then it freezes (trackpad is not clicking anymore) and shuts down.
I tried to reinstall MacOS But it was a pain, it started to show glitches in middle of installation and I could not finish it. I only was able to reinstall MacOS when I put Macbook outside (it is winter and -2 Celcius).
Now situation looks like this, If... -
Hi guys I have a Macbook a1707 with motherboard 820-00281, without liquid damage that behaves strangely, with the battery connected the Macbook does not turn on and the USBC meter stops at 5v in loop, when I disconnect the battery the Macbook turns on and works fine, I have already tried to replace the battery twice without success, as soon as I connect the black cable of the battery the Macbook does not turn on, it stops at 5v and in loop. -

Hello there
I have problem with Macbook Pro 15" 2017, model 2017, MB code 820-00928.
I bought it as broken with some artefacts on the screen, first I thought that this is problem with ribbon cable but after inspectiing ribbon cable I know it is fine. I tried to reinstall macOs and then I figured out that this must be something with GPU as installation freezes at the end (when drivers are loaded). I installed Windows and was able to install every each of drivers except GPU driver, as soon as I tried to install GPU driver - black screen and restart.
