Schematic for the Xiaomi Mi Pad 4 tablet, provided as a 1.86 MB PDF. Tablet diagrams detail the battery and charging path, PMIC outputs, display and touch connections, cameras, audio and the USB port, which makes them the main reference for no-power, no-charge and no-display faults. Search the PDF for net names to follow a rail, find its filter capacitors and test points, and identify the parts on a shorted line. Confirm the tablet variant on the bench matches before trusting part values.
