Gave up on this one, as my friend was offered to return the MacBook with full refund. I think the GPU was toast on this. -
MacBook Pro 16" (2019) A2141: power consumption? Dead GPU? MacOS not installing
A friend brought his fresh-from-ebay macbook pro A2141 after he failed replacement keyboard plugging.
I fixed all the little problems he introduced.
I am unable to install macOS to this device. Both Sequoia and Catalina (from Internet Recovery) start to install, but after ~2-5 minutes into the installation the macbook does a hard restart (max fan spin for a split second, then reboot without chime).
I noticed what I think is a very high power consumption, like 20V/1.7A when activating WiFi for internet recovery, and more like 20V/3.7-4.1A while downloading the recovery image or installing. The battery is charged 100% (as reported when in Recovery)
If I am correct assuming that amp draw is not normal, what is the normal amp meter readings on that model?
How can I find out which part of the system is drawing that power? I cannot boot macOS from external since that is prohibited, and I can't change that setting without an admin password, which I don't have since ssd is formatted^^

Mac crashes and restarts with kernel panic. No water damage on board. Board is clean. Memtest86 showing no errors. The installation Ventura or Sonoma is successful, but after 5-10 minutes of operation, the accident occurs again. Did a DFU restore and revive, twice with success and successfully reinstalled Sonoma. After 5 minutes of work Mac crashes with Kernel Panic. Apple Diagnostic (AHT) does not find errors.
How to localize the problem ? -

As some of you may be aware i had recently acquired a liquid damaged Macbook Pro A1708 820-00840-a which was not powering on, power issues sorted and it was down to a shorted capacitor, please see my original thread on this if you would like to find out more (https://www.badcaps.net/forum/showthread.php?t=103060)
Now that i have the Macbook Pro powering on i am experiencing a multitude of other suspected problems. Ha.
