PDF schematic for the HP 15-ay series laptop, built on the Compal board LA-D704P with the platform code BDL50. The diagram covers power sequencing, voltage rails and signal paths, which helps when tracing a missing voltage, checking a short or identifying replacement parts. It pairs well with a boardview for physical component locations. The 3.05 MB PDF opens in any reader, and its page numbers serve as reference. Confirm the board number and revision printed on the PCB before relying on part values.
