PDF schematic for a Lenovo machine identified only as IB365CX, apparently an IdeaPad-family model, and the name gives no board number or revision. A circuit diagram like this lets a technician follow power rails from the charger input through the regulators, check the power-on sequence and locate shorted lines. Open it in any PDF reader and search by net or part name. Confirm that the board code printed on your PCB matches the one on the schematic title block before trusting values or pinouts.
