Schematics for the Wistron JM70-PU motherboard, revision R-2, supplied as a 1.18 MB RAR archive. The name does not state the laptop brand. Inside should be a PDF circuit diagram for following power rails from adapter input to CPU and memory regulators, reading component values and locating where a short or missing voltage originates. JM70 has more than one variant, so check that the PU suffix and revision on the PCB match before using the drawing for repair work.
