Schematic in PDF for Compal project IBQ00, motherboard LA-3301P revision 1.0, compressed into a 1.23 MB rar archive. LA-xxxxP is Compal's board numbering, and the laptop brand is not named in the file. The diagrams serve for tracing power rails, finding the parts in the power-on sequence, checking charging circuitry and following signals when diagnosing shorts or no-boot faults. Compare the board number and revision printed on the PCB with this document, since different revisions can change component values and placement.
