PDF schematic for the Lenovo ThinkPad P1 Gen 3, LPM-3 motherboard, Wistron board 19770-1, in a 2.52 MB RAR archive. The 19770-1 code follows the Wistron pattern, identifying the ODM that designed the board. The diagrams let a technician trace power sequencing, rail sources and signal paths when diagnosing no-power or short faults. Using it together with the boardview of the same number helps locate parts. Check that the number on the PCB matches first.
