Schematic for Compal project AAP21, board LA-C921P, revision 1.0 with the A00 marking, stored in a 4.24 MB RAR archive; no laptop brand is named. LA-xxxxP is Compal's board-number format, used for many OEM laptops. After extraction, the PDF serves for following power rails, checking the power-on sequence and locating parts on a shorted net. Confirm that the LA-C921P code and revision on the PCB match before relying on component values or connector pinouts.
