Lenovo B570 archive referencing Wistron board LZ57, a 1.26 MB RAR. Wistron uses short project names such as LZ57 for its laptop mainboards, and that name usually appears on the PCB, so check it and the revision before relying on the documents. The contents are not specified but are likely schematic material for tracing power rails, enable signals and test points. Unpack it with 7-Zip or WinRAR and open the files in a PDF reader or a suitable boardview program.
