Boardview for Compal board LA-J061P, listed under Lenovo, in a 509 KB ZIP archive with no revision given in the name. Compal uses LA-xxxxP numbers for its laptop mainboards, and the same board can serve different models, so check the PCB marking. Extract it and load the file in a viewer such as OpenBoardView or FlexBV to locate parts, follow nets, find test points and spot which components share a shorted rail. It pairs with the LA-J061P schematic for full circuit tracing.
