Schematic for the HP DV4 with Compaq CQ40 and CQ45 siblings, Intel platform with discrete graphics, on Compal board LA-4102P. The LA- code follows Compal ODM numbering and should match the PCB marking and revision before use. Because this is the discrete build, the GPU, its video memory and their dedicated supplies are included alongside system power, charger and I/O pages. Use it for tracing rails, measuring test points and isolating shorts. The 1.96 MB PDF opens in any standard reader.
