Acer Aspire 7520 circuit diagram in PDF, tied to mainboard LA-3581P. The LA- prefix with a trailing P follows Compal's numbering, so Compal is the ODM behind this board rather than Acer itself. Technicians use such schematics to follow power sequencing, find where a short to ground originates, and check expected voltages at connectors and regulators. Make sure the LA-3581P marking and revision printed on the PCB match before trusting the reference designators and values shown here.
