Nokia N81 schematics collected in an 875 KB PDF. The file name names only the model and gives no board revision or service manual level, so compare the PCB with the diagrams before trusting references. Nokia schematics of this era are used to trace battery and charger lines, check the power management ASIC outputs, follow display, keypad, camera and audio paths, and diagnose no-power, no-charge or no-signal faults. The file opens in any PDF viewer and can be printed for use at the bench alongside a layout drawing.
