Lenovo boardview for board NM-E491 REV1.0 produced by LCFC, with JE44A noted as the project code. The archive is a 4.32 MB ZIP. Open the extracted layout in FlexBV, OpenBoardView or Boardviewer to view component positions on top and bottom layers, click through nets and identify test points for voltage checks during no-boot or no-power diagnostics. LCFC, Lenovo's in-house ODM, uses the NM- prefix for its mainboards. The board number and revision printed on your PCB should match this file, since other revisions may relocate parts.
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 @cynetitsolution. Enginerys does not host this file.
