Schematic for the Lenovo ThinkBook 13s Gen 3 ACN, the AMD-based model, with the board code LV550 and the number 203075 in the name, supplied as a PDF inside a RAR archive. The 203075 token follows a style common to some Lenovo board identifiers, but only the stated values should be relied on. Use it to trace power rails, charging and sequencing signals, and to find component locations during diagnosis. Match the code printed on the motherboard before trusting part references.
