RAR archive of 1.92 MB covering two Compal board numbers, LA-B751P and LA-B753P, likely variants sharing one design. The name gives no revision or laptop brand, and the file list is not stated; schematics are the usual content. Compal uses LA- numbers for notebook mainboards, and related numbers often differ only by GPU or feature options. Use it to trace power rails and signals and locate parts on either variant. Extract with WinRAR or 7-Zip and confirm which number is printed on your PCB.
