I desoldered the charging IC and the short from the _SW1 and _SW2 pads are gone. But the _ISNS pads are still shorted to ground. Could this be because of the burn hole? Or ist this normal?
Also i cleande the area, this is what it looks like. I ordered a new part from aliexpress, i hope it arrives in a week
FEF...

OK, I dont understand why the SSD should have a damage? The lines from the UG800 don't go to the SSDs as far as i've seen it? But the point to check the other components was a good one, the charging IC UG400 has a burn hole in it, like you mentioned it. Thats the IC the lines go to, a CD3217B12BCE.
I will try to desolder it and check if the lines are still shorted to ground.

Thanks for the answer, i will do it later.
I tested one more thing, hte pins are shorted to ground. Also the line of pins next to the affected ones (..._SW1, ..._SW2)

Hello,
I'm new to this Forum, so I hope it's the right place for this topic.
Im a student from germany, and as a hobby I repair electronics. I started microsoldering maybe 1-2 years ago.
I have a MacBook Pro 14" m1 Pro with 10 Cores and 16/1tb storage. The board Number is 820-02098-A.
The MacBook has a light water damage. Coffee got spilled over it, but the Mac continued working only the battery didn't charge anymore and when the battery was empty the Mac turned off and doesn't show any sign of life now.
I opened it up and there were only three drops of coffee...
