Boardview for the Lenovo HE430 and HE530 platform on LCFC board NM-D481, revision 1.0 as indicated by REV10, in a 1.40 MB RAR. HE430 and HE530 are LCFC project codes, and NM numbers are LCFC mainboard identifiers. With the layout you can locate parts by designator, highlight nets and find test pads for voltage measurements during no-power, no-boot or short diagnosis. Pair it with the schematic for signal names and values. Verify the board number and revision on the PCB, then open it in FlexBV or OpenBoardView.
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 @BoardSchematic. Enginerys does not host this file.
