Lenovo schematic archive labelled I4X0MS version 1.0, with a PDF document inside a RAR file. The name does not say which notebook models it covers; I4X0MS reads like a board or project code, so the title block in the PDF should confirm the target machine. A schematic of this kind is used to follow power rails and enable signals, read the power-up sequence, and look up part values around the charger, EC and regulators. Extract it with 7-Zip or WinRAR, then compare the code with your board.
