PDF schematic for a Dell 5400 series laptop, platform EDC41 with Compal motherboard LA-G891P, about 3.49 MB. The same EDC41 LA-G891P design also appears in the Latitude 5500 family, so it pairs naturally with that boardview. Use the diagrams to study the power-on sequence, measure expected rail voltages, identify the EC and SPI flash connections and track down a short on a specific net. Open it in any PDF reader, and confirm the board number and revision on the PCB before relying on component values.
