Circuit schematic in PDF form for the Lenovo BX260 platform built on the NM-A531 board, delivered as a 2.88 MB RAR archive. The NM-A prefix belongs to the LCFC numbering scheme, the ODM behind many Lenovo laptops. A diagram like this lets you follow power sequencing, check which rails feed the CPU and chipset, and trace signals between connectors and controllers. Pair it with the matching NM-A531 boardview for physical locations, and verify the board number silkscreened on the PCB first.
