Another PDF schematic for the Lenovo ThinkPad L13, project Lar-1, Wistron board 18834-1M, labelled sovp_mb in the name. At 3.69 MB it may be a different release than other copies. Wistron board numbers use this five-digit pattern with a suffix. The circuit diagrams help trace power rails, find the source of a short, and follow the EC and power-on sequence. Any PDF reader opens it. Make sure the suffix on the PCB matches before relying on part values.
