Archive for the Lenovo ThinkPad L430 with a Wistron-built board, marked LCD-1 and 11248-SC, in a 1.72 MB RAR. Wistron identifies its designs by a project code plus a five-digit number, and the SC suffix commonly denotes the schematic. Use the drawings to trace rails from the adapter input through the charger and system regulators, find the EC and BIOS chip and check signals on connectors. Compare the number on the PCB silkscreen with the one here, because L430 units can use more than one mainboard version.
