Circuit diagram for the Compal LA-2771 board at revision 0.8, a PDF of about 1.03 MB. This is an older Compal design identified only by its LA code; the laptop brand and platform are not stated in the name. The schematic lets a technician follow the power path from adapter input to CPU core voltage, check the sequencing signals, look up component values and locate the source of a short. Confirm the board number and revision on the PCB, as a 0.8 drawing may not match final production boards exactly.
