does not power on
customer came in for data recovery
disassembled the board and connected to power supply and got

PP3v3_R3V0AON - 3.288v
ppbus - 8.59v

however with keyboard attached ppbus drops to 8.18. have tried new keyboard w/ cable as well. all i really care is about data. does this have a way to grab the data like the mbp 2017

There is no external access for SSD area.
It should start automatically, no keyboard need to be connected.
Check for coils voltage; and USB activity, if is the case.
