MacBook Pro 2015 15" DG shuts down at 50% on progress bar

Tried to start my Macbook last night but would restart as soon as it reached 50%~ on the progress bar. When trying to boot into a recovery mode it would restart at about 30% on the progress bar and my windows 10 install would also fail to boot. Made a Big Sur install USB on another computer and that too restarts after 30%~.

So far I've tried:

  • PRAM Reset
  • SMC Reset
  • Disconnected Battery
  • Removed SSD
  • Different 85W Magsafe adapter
  • Big Sur Installer USB (Without Battery or SSD after failing with them).
  • Thunderbolt Ethernet Adapter in both Thunderbolt ports

None of which have changed the restart point. Did have a "Service Recommended" notice on the battery (Serial is not covered under Apple's recall, either not affected or previous owner did it), hence testing without the battery, was undervolted and wattage limited with Volta. Has Catalina, Big Sur and Windows 10 installs on it (Can see all in bootloader).

Screen appears to have yellow hue in top left corner, red in top right and bottom left corner, which I don't remember seeing before.

Thanks for any help.

Update (10/16/2021)

I reopened the Macbook and noticed some very minor corrosion/some sort of goop on the magsafe connector, small enough I wouldn’t have cleaned it if I did not have an issue. Ended up removing the entire logic board to check the underside at the same time and saw nothing on the backside. Decided to connect the SSD, IO board and boot it with a USB Mouse and Keyboard on a HDMI monitor. Booted right up and did the sensor freak out with Fans at 100% usage and CPU locked to 800mhz and iGPU with 0.00GHz request (Intel power gadget). Catalina, Big Sur and Windows 10 all worked fine although device manager in Windows gave the GPU a code 43 error and a facetime camera error (Wasn’t connected). Slowly pieced the machine back together after this and if I connect the trackpad connector the fault returns, this connector also needs to be connected for the keyboard to work it seems. Battery is completely dead even though MacOS says it holds charge, unplugging magsafe with “55%” charge just instantly kills the machine.

TLDR: Booted with just logic board completely fine, anytime I connect the trackpad problem returns, battery is dead dead but doesn’t effect boot issue.

Given the systems age have you replaced the battery yet?

What is the color of the MagSafe LED? Amber, Green or not lit.

As it used to normally, goes green as it's plugged in before turning orange a second or two later. Battery has not been replaced for the time I've owned it, was looking into doing it when I had time.

Let’s get a better view of things, install this gem of an app! CoconutBattery take a snapshot of the apps main window and post it here for us to see 기존 질문에 이미지 추가하기

I cannot boot into MacOS or even into a recovery partition with or without the battery installed (ref: original post). I disconnected the battery as I also believed this could've been at fault but it didn't effect the problem

OK, lets give this a try restart the system with the MagSafe plugged in press the Shift (⇧) key to enter into Safe Mode
