RAR archive holding the PDF schematic diagram for the Compal LA-D993P motherboard, revision 1.0. The LA-xxxxP pattern is Compal's board numbering, so the laptop brand that used this board is not stated in the name and should be confirmed from the PCB or service label. Technicians use such a schematic to trace power rails, check the power-on sequence, follow signals between chips and identify parts near a short. Extract it and open the PDF in any reader, and verify the revision printed on the board matches 1.0.
