RAR archive of roughly 262 KB for the Compal LA-M214P motherboard, revision 1.0. The name does not say what is inside, so it may hold a boardview, a schematic or both, and the contents should be checked after extraction. LA-numbered boards are designed by Compal and supplied to several notebook brands. Such files help when tracing power rails, finding components and checking signal paths during repair. Make sure the board number and revision printed on the PCB match before relying on the data.
