Schematic PDF for a Dell 14-inch laptop on Compal board LA-B843P; the hsw tag indicates the Intel Haswell platform. These diagrams help a technician trace power rails from the DC jack through the charger to the CPU regulators, read signal names and look up component values for replacement. Any PDF viewer will open it, and searching net names speeds up diagnosis. LA-xxxxP is the Compal ODM numbering; check the revision printed on your PCB, since layouts and part values can differ between revisions.
