Schematic PDF for the Compal/LCFC NM-A281 laptop motherboard used in Lenovo notebooks, archived as an 879 KB RAR. The name does not give a revision, so compare it with the revision silkscreened on the PCB. NM-xxxx is the LCFC numbering pattern for boards it designs for Lenovo. The diagrams let a technician follow the power-on sequence, check the charger and system rails, locate the EC and SPI flash, and trace signals when diagnosing a short or a no-boot fault. Open it with any PDF reader.
