Compressed schematic set for the Lenovo U31-70 on the Compal LA-C311P mainboard, with the project codes AIVS3 and AIVE3 given in the name. The RAR archive is about 1.19 MB and opens with any common extraction tool. Compal uses LA-xxxxP numbering, printed on the board's silkscreen. Use the drawings to follow power distribution, check the charging path, find the EC and SPI flash and work through no-power or no-display faults. The name gives no revision, so compare the title block with the marking on your PCB.
