Compal schematic in PDF format for the VBL20 project, board number LA-9241P, archived as a 2.63 MB RAR. Compal uses a project code like VBL20 together with an LA-xxxxP board number, and both are printed on the PCB; the laptop brand is not stated in the name. The PDF shows the power tree, EC circuitry, chipset connections and net names for tracing rails and checking signals. Make sure the board revision on your unit matches the schematic, since component values sometimes change between revisions.
