Lenovo schematic in PDF for the LCFC GT5A0 / GP5A0 platform, board number NM-C641, compressed into a 2.91 MB RAR. LCFC is Lenovo's in-house ODM and uses the NM-xxxx board-number pattern, printed on the PCB. The diagrams let a technician trace power rails, follow enable and power-good sequencing, check charger and CPU VRM circuits, and locate the source of a short. The name states no revision, so compare the revision silkscreened on your board with the one in the schematic title block.
