Schematic for Lenovo LCFC board NM-A681, revision 0.2, in PDF at roughly 700 KB. The name does not state the laptop model, so identify it from the NM number on the PCB. Revision 0.2 suggests an early engineering drawing, and component values or placement may differ from production boards, so cross-check against the actual hardware. LCFC uses the NM-xxxx numbering for Lenovo mainboards. A technician uses such pages to follow power rails, check enable signals and locate a short; any PDF viewer opens it.
