Hi,
I troubleshoot the 820-3332-A for "NOT TURN ON". I need some advice for what to do to solve the problem!

Hi
I own a A2551, 2020 MBP and it stopped charging after a software update. Now the battery is all drained, neither i can power it or charge the battery.
When i read the voltage in usb-c ports it pulls something around 5V then machine reverses the current, then sometimes pulls something like 2A then 0.24A.
I can see current is flowing in only 3 out of 4 ports. Does this sound like something you've experienced before?

Hello, I use macbook pro 2012 md103. When I want to replace the battery I accidentally damaged my logic board. I only damage a small part of the logic board, it only makes a little mark on the logic board, but it causes my macbook to take a long time to charge. From 0 to 100% it's took 15hours.

Hola tengo un MacBook pro 820-3115-b que me llega no enciende da luz verde en el cargador he revisado los voltajes de entrada y parecen correcto sin la batería conectada y con cámara térmica compruebo que el u7000 se calienta . Mi pego ya es que voltajes principales tendría que revisar para saber si anda todo bien . Es decir que voltajes me recomiendas revisar para ver dónde está el problema.
