Schematic for the Acer Aspire E1-572G laptop, built on a Compal design, in a PDF of roughly 1.11 MB. The name ends with LA but omits the full board number, so find the exact LA-xxxxP code in the drawing title block and compare it with the mainboard silkscreen, including revision. Compal is the ODM using that numbering. Technicians use the diagram to trace charger and regulator outputs, verify power sequencing, locate test points and track down shorts. Any PDF reader opens it.
