Another copy of the Compal NM-A271 schematic for the Lenovo G40, ACLU1 and ACLU2 projects, 1.25 MB PDF matching the other files of this name. The two project codes indicate the document covers more than one variant of the board, so confirm which applies before relying on specific values. Technicians use it to follow the power-on sequence, measure expected rail voltages, inspect charger circuitry and locate components on a shorted line. Check the NM-A271 marking and revision on the motherboard first, then open the file in any PDF reader.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @schematicslaptop. Enginerys does not host this file.
