Zip archive of board photographs for the LCFC NM-C821 motherboard, the platform used in Lenovo IdeaPad 3 models. At 16.7 MB it should contain high-resolution images of the board sides. Reference photos help when parts are burnt, missing or lifted, showing the original placement, orientation and markings of components and connectors. They complement a schematic or boardview when resolving which part belongs on a damaged pad. Compare the board number and revision visible in the photos with your own PCB, since layouts can change between revisions.
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 @vinafix_bios. Enginerys does not host this file.
