PDF schematic for the Lenovo IdeaPad Y450, with KL1 given in the name as the project or board code. No board revision or ODM is stated, so confirm the code and the PCB markings before using it on a specific unit. A diagram like this is used to follow power sequencing, locate the embedded controller and its signals, find fuses and coils on the input path, and work out which rail is shorted. At 2.51 MB it is a fairly full document that any standard PDF viewer can open and search by net name.
