Schematic for the Dell Inspiron N5110 laptop as a 1.45 MB PDF. The name states only the brand and model, without a board number or revision, so confirm against the motherboard silkscreen before relying on part values. Use the diagram to trace the standby and main power rails, follow enable and power-good signals, and narrow down which capacitor or regulator is pulling a rail to ground. Readable in any PDF viewer, where text search by net name helps navigate the many pages of a complete laptop set.
