ZIP file for the ASUS X540UP notebook, 146 KB, whose name gives neither board number nor revision nor a list of contents. The size is consistent with a boardview, and another X540UP layout in this index uses board 60NB0DE0-MB5010, but the actual contents need verifying. Boardview files load in viewers such as OpenBoardView and help with locating parts, following nets and finding test points. Check the part number and revision printed on the PCB before relying on the layout for repair work.
