Main board schematic for the Lenovo A320 provided as a PDF of about 1.38 MB. The file name gives only the model and the abbreviation MB for motherboard, without a board number or revision, so confirm the PCB identity by comparing the document title block with the markings on the board. Such schematics let a technician trace power supply rails, follow signal paths between chips and connectors and locate test points during fault finding. Open it with any PDF viewer and use text search to find component references quickly.
