Lenovo boardview for LCFC motherboard NM-A361 revision 1.0, with ACLU3 and ACLU4 as the board codenames, delivered as a 2.94 MB TVW file. NM- codes come from LCFC, Lenovo's own ODM, and one board often serves several models, so confirm the code on the PCB. TVW is a Teboview layout format that requires a viewer capable of reading it, such as TVW-compatible tools or FlexBV. It lets you find parts, trace rails and signal paths and locate test points while diagnosing.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @boardviews. Enginerys does not host this file.
