Compal LA-D707P documentation at revision 1.0, labelled with project code CDL50, provided as PDF inside a 2.90 MB RAR archive. Compal uses LA-xxxx board numbers for notebook mainboards it designs for several brands, and the CDL50 code identifies the project. The PDF is probably the schematic, useful for following power sequencing, charger and EC circuits and checking component values. Verify the LA-D707P marking and revision on the board, and note that the laptop brand is not stated in the name.
