Does anyone have a LENOVO schematic
MB : 20U7-0002GE
MAIN : GL4A5/GL5A5 NM-C741 Rev:1.0
CPU : AMD RYZEN 5

There is a difference in the 20V power supply from the scheme posted here.

Thank you for the scheme you set up. Meanwhile I found that schematic and layout of the motherboard.
My current problem:

I have Lenovo L15 GL4A5/GL5A5 NM-C741 Rev: 1.0 (20U7-0002GE)
There are small differences between the scheme you posted and this motherboard.
My problem is that on the USB-C connector on the pins I have voltage up to approx. 5V (measured on L6301 and L6302).
Do you have any idea what the problem is because the computer does not respond to the power button?
My only idea is that L15 only allows a voltage of 20V later.
Tried with 2 different power supplies because I don't have the original AC/DC adapter. The result is the same 5V at L6301 and L6302.
