Boardview for the Lenovo board GY552 NM-C991, in TVW format inside a 1.40 MB RAR archive. The NM- prefix follows LCFC numbering, the Lenovo owned ODM that designs these boards. The layout shows component positions, nets and test points, letting you trace rails and locate a short quickly. TVW files open in Teboview and some other boardview programs. Confirm the board number printed on the PCB reads NM-C991 before measuring, and pair it with the matching schematic for circuit details.
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 @schematicslaptop. Enginerys does not host this file.
