RAR-compressed schematic for the HP BDL50 platform, covering Compal board numbers LA-D702P and LA-D707P, about 2.49 MB. Inside should be the PDF diagram, which needs only a standard reader once extracted. Compal's LA-series numbering identifies the PCB, and two numbers usually mean a main board plus a related secondary board. The drawing helps trace rails, locate MOSFETs, coils and test pads, and work through a short or a power-sequence fault. Match the LA number silkscreened on your board to the right section first.
