Mainboard schematic in PDF for LCFC board NM-D461 revision 1.0, carrying the project codes HS45A and HS55A, packed into a 2.98 MB RAR. The diagram details power rails, enable sequencing, the EC area, USB and display connectors and component references for diagnostics. NM- numbers belong to LCFC, the ODM behind many Lenovo laptops. Match the board code and revision on the PCB to the title block, and pair the PDF with a boardview if you need physical part locations.
