Compressed package for Lenovo board NM-A411, revision 1.0, a number following the LCFC scheme used on Lenovo-designed laptop mainboards. The model name is not stated, and at 490 KB the archive likely contains a boardview or a small firmware file rather than a full schematic. Boardviews of this kind open in OpenBoardView or FlexBV and let you locate parts and test points quickly. Verify that NM-A411 and REV 1.0 are printed on your PCB before relying on any of the data inside.
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.
