PDF schematic for the Lenovo Zhaoyang E680, E680A and E290, 1.04 MB, sharing one drawing across these models. No ODM, board number or revision is given in the name, so verify the board code in the title block against what is printed on the motherboard before relying on it. The schematic lets you follow power rails and their enable signals, check which components sit on a shorted line and look up correct part values when replacing damaged parts. Any PDF reader opens it.
