Revision R0.2 schematic for the Compal LA-4231P board, delivered as a 1.11 MB RAR archive. The name includes no laptop brand or platform detail. The LA-xxxxP code is Compal's ODM board numbering, applied to notebooks the company builds for other vendors. Unpack the archive and open the document in a PDF viewer to trace rails and signals, read component values and find test points. As an early R0.2 release it may differ from production boards, so compare the revision printed on the PCB.
