Wistron schematic package for the Hellcat 15 Upsell design, project or board number 19828, provided as a 5.78 MB RAR holding the PDF. Hellcat is the Wistron project code; the laptop brand is not given in the name. Extract it and read it in a PDF viewer to trace power rails, follow signal paths and find component values. Wistron designs often have several variants under one code name, so check that the number printed on the PCB matches 19828 before relying on it.
