Lenovo boardview for Compal board LA-M653P, revision 1A, compressed into a small 95.7 KB ZIP. Compal names its main boards in the LA-xxxxP style, with the number silkscreened on the PCB. After extraction, the file opens in boardview programs such as OpenBoardView, FlexBV or BoardViewer, showing part locations, net names and test points. It speeds up finding a shorted capacitor or tracing a missing rail. Make sure the revision on your board is 1A, since layouts may change between revisions.
