PDF schematic for the board numbered LA-1511, revision 1.0, with no brand or laptop model given in the name. LA-numbered boards are Compal designs, and this number also appears on Acer TravelMate 420 series documents. The drawings cover power conversion, chipset connections and peripheral interfaces, helping a technician trace missing voltages, check signal paths and read component values. Confirm that LA-1511 and the revision on the PCB match before working from it, since layouts and parts can change between revisions.
