Compal JAL30 board layout, model LA-4121P at Rev 0.3, delivered as a .CAD boardview inside a 229 KB RAR archive. JAL30 is the Compal platform code, and the LA-number follows the Compal scheme used across many OEM laptops. Load the extracted file in OpenBoardView, FlexBV or a similar viewer to find component locations, trace a net from connector to chip and spot test points for probing power rails. Early revisions can differ from later boards, so check the revision printed on the PCB matches 0.3.
