Schematic in PDF form for the LCFC board NM-A771, project CYG11, at the SVT stage. SVT usually refers to a system validation test build of the design. The 1.99 MB RAR can be read in any PDF viewer. LCFC is the Lenovo-owned ODM behind NM-xxxx numbers, so the board belongs to a Lenovo laptop. Use it to follow power sequencing, the charger and the EC signals, and confirm that the board number on the PCB matches.
