Schematic in PDF form for a Dell power adapter, with no model or wattage given in the file name. At 228 KB it likely covers one charger design. Use it to trace the mains input filter, bridge rectifier, PWM controller, transformer and output stage when a brick gives no output or cycles on and off. Dell adapters also carry an ID line used by the laptop to recognize the charger, worth checking when a unit charges but is not identified. Compare the part numbers on the PCB with the drawing before relying on component values.
