Compal-designed schematic for the Lenovo B50-70, board LA-B092P revision 1.0, provided as a 966 KB PDF. Compal identifies its laptop boards with LA-xxxxP codes, and that number together with the revision is usually printed near the edge of the PCB, so match it first. The diagram is useful for tracing the charger circuit, the 3V/5V always-on rails and the CPU core supply, and for working out which component sits on a shorted line. Open it in any PDF reader and search by net name or reference designator.
