Schematic for Compal board LA-4251P at revision R0.2, an early engineering stage, stored as a 949 KB RAR archive. Compal uses LA-numbers for main logic boards it designs for various notebook brands. R0.2 drawings can differ from mass-production boards, so check component designators and values against the actual PCB before trusting them. With the PDF open you can follow the power-on sequence, read rail names and voltages, and locate signals feeding the charger, CPU regulators and memory. Extract it with WinRAR, 7-Zip or a similar tool.
