Hi,
I have an A1706 820-00239-A with no power.
I once fixed the PM_BATLOW_L lines.
UB300 and UB400
with battery:
-restarts the ammeter on all USB
-Now on 2 usb ports (UB300 and UB400) I have 20v. Present PP1V1_UPC.
-On 3100 and 3200 I have 5v. PP1V1_UPC is missing on both.
Without batteries, there is 5v everywhere
- restarts the ammeter on all USB
- PP1V1_UPC have 0.53 in Diode-Mode

"On 3100 and 3200 I have 0v"
Do you mean 0V on USB-C meter?
It shows 0V, no black screen?

Compare diode mode readings between J3300 and JB500.

Don't you have the classic USB-C meter?
I don't understand what the people see on that blue bulshit.
