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^^

hello. I have 2141 on which I can't restore macOS. When loading, no buttons are active, it immediately wants to restore the Internet. But then I see an error 2100f. It doesn't boot from an external USB.
I can't flash it through dfu because I don't know the version of macOS that was on it. Help
By the way, for some reason it heats up inadequately and the coolers are at maximum -
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 ? -
I have just got in a MacBook Pro A2338 which was initially displaying the Apple logo followed by an explanation mark in a circle as described here:- https://support.apple.com/en-gb/102164.
After some error messages attempting to revive and restore the machine via DFU mode i have finally got the machine revived however now the issue seems to be when attempting to install macOS Sequoia via a bootable USB installer or via macOS recovery the machine just keeps freezing and restarting before the installation is complete, usually the installation has just started or is mid way trough before...08-10-2025, 11:04 AM -
