Thank you. We've tried it again with a cleaned ME region and while it did manage to boot into an installation media, the installation of High Sierra took ages. The system now only boots to 90% and stays there indefinitely.
The board powers on fine but gets stuck with around 70% on the boot progress bar. The fans also gradually start spinning to a far higher RPM than normal. After a short while, it then simply reboots. Alt + D doesn't show any issues.
Any ideas?
I have 0v on 3v42_g3h without battery
on Q7010 pin 1-3 0v, pin 4 16,26v - 15,99 is not stable, pin 5 and 6 have 16,46 v drop down every second to 16,2.
when i connect a charged battery it turns on and works perfectly, but adapter-sense has 0V, no green light and CHGR_AGATE_DIV is 16v, otherwise no power on any lines with a magsafe connected. PPDCIN_G3H is there.

any ideas?
Lately we are more frequently getting Macbooks with the following Problem:
It only turns on when its cold and the battery is completly drained. works for a time. Shuts down at a random time and doesnt turn on.For the time after it "crashes" it gets hot. It does that until the battery gets low...
Now, we changed the SMC and the short is gone. Still 5v on the charger tho.. I noticed that all ports except one draws about 150mA. Only one is drawing just 11mA. Does that tell us somethng ? or is it irrelevant
It restarts constantly... sometimes it does manage to boot and the usual first startup screen is visible. In the part where you can connect to a wifi network it tells that it has to do a critical update. after i connect it, it tries to install something but fails with the message: "an error has...
board with water damage, it takes 1.4 Amp, turns on and shows an empty battery sign, but doesn't charge the battery(or a new battery) and then turns off and goes to 0 Amp, what is SMC bypass mode? How can I try the SMC bypass mode?
I have the same board with water damage and the exact same problem, it takes 1.4 Amp, turns on and shows an empty battery sign, but doesn't charge the battery(or a new battery) and then turns off and goes to 0 Amp, what is SMC bypass mode? How can I try the SMC bypass mode?
This board is showing 5.2V on the charger. The USB C Controllers have already been replaced and the issue persits.
What do you check/how do you find the responsible port? And what could be some more possible causes?
