Circuit diagram from LCFC for the Lenovo motherboard NM-C181, supplied as a single PDF of about 3 MB. The file name gives no laptop model or revision, so identify the machine by the board number printed on the PCB. LCFC is Lenovo's own design arm, and the NM- prefix is its standard numbering. Use the schematic to trace power sequencing, locate the EC, charger and VRM circuitry, and read pull-up and signal paths, ideally alongside the matching NM-C181 boardview for physical locations.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @cynetitsolution. Enginerys does not host this file.
