PDF schematic for a Compal-designed laptop motherboard, board number LA-D704P. LA- numbers are Compal's own project codes, and Compal builds boards for several laptop brands. The name does not say which brand or model uses this board, and it gives no revision. Use it to trace power rails from the adapter input through the charger and the system regulators, locate signal paths and check pull-ups. Confirm that the LA number on the PCB matches exactly, because boards with similar codes can differ widely.
