Boardview for the Lenovo CG520 motherboard, LCFC board number NM-A804, revision 1.0, supplied as a ZIP archive of about 1.6 MB. LCFC is the Lenovo-owned design house that uses the NM- numbering pattern. With a boardview open in OpenBoardView, FlexBV or a similar tool you can find a component by reference, see which nets it connects to and pick test points while diagnosing shorts or absent voltages. Make sure the board printed NM-A804 and rev 1.0 is the one on your bench, as the related NM-A801 differs.
