Schematic for Compal motherboard LA-D707P, revision 1.0, with CDL50 as the project code; the notebook brand is not given in the name. The 3.64 MB PDF is a fairly complete drawing set covering power regulation, the processor, memory and I/O. Technicians use it to trace rails back from a shorted capacitor, identify missing voltages in the startup sequence and find test points for EC, clock and reset signals. Compal applies LA- numbers to boards made for several OEMs, so match number and revision on the PCB.
