Schematic in PDF for motherboard NM-F861 revision 1.0, listed under Lenovo; no laptop model is named in the file. NM-xxxx numbers are used by LCFC, the Lenovo-owned design and manufacturing company. The document lets a technician trace power rails, follow the power sequence and look up component values and reference designators while diagnosing no-power, no-boot or charging faults. Open it in any PDF viewer, search by net name, and check that the board number and revision on the PCB match before measuring.
