Hello everyone,

This is my first post after browsing this wonderful treasure trove of knowledge for many, many evenings. I've decided to learn how to fix these things, properly.

My patient is an A2338 Macbook Pro M1 (late 2020).

It had some corrosion around JT710 and JT700 caused by liquid spill, as well as against the protective barrier around the USB-C chips UF000 and UF100. So I took the main board out and cleaned it with a toothbrush and alcohol, then with alcohol in an ultrasonic cleaner. Cleaned the touchbar flex connectors as well. The board looks...

Hi everyone - first time poster on here looking to embark on my first repair! Thank you in advance for any help!

My Macbook only turns on when the charger is plugged in and only the trackpad and fans show signs of life. The display, caps lock light and touchbar do not turn on. There was previous liquid damage to the touchbar but after cleaning and drying the laptop was operational for a year without any issues. There doesn't seem to be any sign of liquid damage to the board, at present.

What I have done so far:

- All of the routine diagnostic methods including...

Got this waterdamaged where oxidation happened under shield on touchbar cable. It showed image but no touch. After I cleaned and resoldered everything except ic (it is sealed anyway) i am getting touches however i find it a bit hit n miss where it works but sometimes missing dragging. Tapping seems fine. I think it might be something to do with this big cap which might be LDO or something. I placed 10v 2.2uF cap there. Anyone could measure it from good/dead touch bar lying around ?...

Hi! This Mac has been an headscratcher for me, I can't seem to figure out the issue. The Macbook has gotten water damage to the front of the keyboard connector and battery connector. The keyboard connector was dead, by which I mean it was completely corroded and I have replaced it with a brand new one.
I have verified all the pins are connected to the main board and the main voltages (PP1V8_AONSW_KBD_ISNS and PP3V3_AON_KBD_CONN) are both present, with and without keyboard attached.

Unfortunately, the keyboard does NOT want to work, caps lock LED not functioning as well as any...

Hi to all,
the owner of this macbook brought it to me after a fall, that hit the upper right corner of the top case.
Luckily enough, the screen and all other parts of the machine haven't been damaged, only the touch bar wasn't lighting up anymore, and the macbook began to behave strangely, because it seems to start and work fine but suddendly it shutsdown (and at the same time the fans make a high rotation for half a second, as if an animal was annoyed by something...) at random times, sometimes after 2 minutes, sometimes after 5 minutes, but never over 10 minutes, then restarts...
