Boardview covering the Lenovo ThinkPad E14 and E15 Gen 2 main board NM-D011 at revision 0.4, as a 454 KB BRD file. NM- codes belong to the LCFC scheme used on many Lenovo designs. Open it in OpenBoardView or FlexBV to locate components, test points and nets, measure rails and isolate a shorted capacitor. It pairs naturally with the matching schematic. Verify the revision printed on the PCB, because placement can differ between board releases.
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_schematics. Enginerys does not host this file.
