RAR archive holding the schematic PDF for the Dell Hellcat 13 TGL mainboard, number 19827-1, with the Dell part reference DT3DN in the name. Hellcat is the platform code name and TGL points to Intel Tiger Lake. The 19827-1 pattern is typical of Wistron-built Dell boards. Extract the PDF and use it to trace power rails, check enable and power-good signals, read component values and follow the boot sequence while diagnosing a dead or shorted board. Confirm the number on the PCB matches before working from it.
