Schematic for the Dell Precision 3520 mobile workstation, built by Compal under project codes CDP80 and CDP81, board LA-E152P. LA- is Compal's own board number pattern, so the drawing follows Compal's usual layout of power sequencing, charger and EC pages. Technicians use it to trace power rails, find which MOSFET or regulator feeds a shorted line and follow signals between chipset and connectors. Extract the RAR and open the PDF, then confirm the board number and revision on the PCB match.
