Schematic for the Lenovo G50-80 laptop, board NM-A361, in a 3.58 MB PDF. The NM-xxxx numbering belongs to LCFC, the Lenovo and Compal joint venture that designs many Lenovo consumer notebooks. No revision is stated in the name, so compare the title block with the markings on the mainboard. This diagram lets a technician trace power rails, review the EC and charger circuitry, check the power-on sequence and locate parts linked to a short. A standard PDF viewer handles it, with text search for net names.
