Schematic for Compal motherboard LA-L191P, project code GH53G, revision 1A, in a 5.27 MB PDF. The LA- prefix identifies Compal as the board maker, while the laptop brand is not named in the file. Technicians use this to follow power rails from the adapter input through the standby and main regulators, check enable and power-good logic and look up component values. Confirm that the silkscreen on your board reads LA-L191P r1A, as other revisions may differ in parts.
