Archive tied to the Lenovo ThinkPad P50 with mainboard NM-A451, also labelled BP500 in the name, packed as a 4.25 MB RAR. The name does not say whether it holds a schematic, boardview or firmware, so inspect the contents before relying on it. NM-prefixed board numbers belong to LCFC, the Lenovo-owned ODM, with BP500 being the project code. Repair material like this helps with locating components, measuring power rails or restoring the flash. Match the board number on the PCB first.
