Wistron schematic in PDF form, packed in RAR, for board 18803-2, with CFL in the name, which usually refers to Intel Coffee Lake. The laptop brand is not stated, so match the board number on the PCB, a Wistron style five-digit code with a dash revision. The schematic is used to trace power rails and signals, find component references and diagnose shorts or missing voltages. Check that your board revision is 2 before trusting values.
