Laptop schematics for the Dell Latitude E7240 ultrabook, made by Compal under board number LA-9431P, in a 1.53 MB PDF. Compal uses the LA-prefixed numbering seen on the PCB silkscreen, and the number on your board must match. The diagrams cover power rails, the power-on sequence, charger and connector pinouts, helping trace a missing voltage or find a short. Open it in any PDF reader and search net names to jump between sheets.
