PDF schematic for the Lenovo ThinkCentre M70s desktop, covering the I470MS motherboard at version 1.0, stored in a 1.66 MB RAR archive. The circuit diagrams let a technician follow power sequencing and voltage rails, check the expected values around the VRM, and trace signals between the chipset, the slots and the connectors. Any PDF reader will open it, and text search helps you jump to a net name. Before you start measuring, confirm that the board marking and revision on your unit match I470MS V1.0.
