Circuit diagram for Compal board LA-3331P, labelled version 1.0, with 0515 in the name, probably a date code. No laptop brand or model is stated, so identify the machine by the LA-3331P marking on the motherboard itself, a numbering style used by the ODM Compal. The PDF opens in any standard reader and is useful for following power rails, locating fuses, MOSFETs and regulators, and diagnosing no-power or short-circuit faults. Check the PCB revision against this version before comparing measurements.
