Boardview for the Lenovo ThinkPad T460 board labelled T460R in the name, LCFC number NM-A581, supplied as a 2.99 MB .tvw file. The revision is not stated, so compare the PCB markings before relying on it. NM-xxxx numbers belong to LCFC, the Lenovo-owned ODM. Opening it in a TVW-capable viewer or FlexBV shows parts, pins and nets, which helps track shorts on main rails, locate the charger or EC circuitry and find measurement points for diode-mode checks on the board.
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. Enginerys does not host this file.
