Schematic in PDF for a Wistron design coded A34, with the variant A34_TGL and the number 203027 also in the name. TGL most likely means Intel Tiger Lake, though the laptop brand is not named. Wistron is a contract manufacturer that builds boards for several notebook brands, so match the project code and number on the PCB against this document. Use the schematic to trace power rails and enable signals, follow the power-on sequence and identify the parts around a failed circuit. Any PDF reader with text search will open it.
