Hmm, this link seems dead

Well.... How do you current limit?

There's a special comms circuit. I am not sure of the needed mods for connecting to a lab bench power supply. It's not as simple as giving 5v, then 20v. There's a handshake of some kind to ensure that the charger CAN provide 20v safely, and i'm unsure of this. I wish this would be answered...

I am also curious if there's anything special about this. Currently, I believe to guess power usage you can inline an ammeter.... but im not sure about current limiting.

How can I verify if a CPU is dead / possibly damaged? My first guess is to look at the CPU MOSFETs / power regulation IC, and look for a short. My guess is I want to remove those from the board, and replace it (and any other MOSFET that is involved in the operation of the power controller)...

Looking at the board, im curious if some components are interchangeable. The 820-1700-A board is still really expensive as a donor, and I'm curious if the 820-01598 board (2019 13in macbook pro) has interchangeable components. Particularly the "U8400 (lcd backlight TI dc->dc boost converter)" on...

Well, ive watched a LOT of rossmann repair videos over the past few years, and learned a lot on electronic engineering and such. I distinctly remember videos where Louis started checking to ensure the CPU / GPU didn't have any issues that'd kill it when powered up. So I know it's a...

I currently bought a broken macbook (A2141), that was water damaged, and want to repair it. I have the necessary tools I've amassed over time, but want to begin. I have decent understanding of electronics and the like (I have watched a bunch of videos of repairs, as well as am a professional...
