SPS-BASE ENCLOSURE 14

HP Base Enclosure 14, part 840657-001, is the bottom chassis case identified for 14-inch HP products. It forms the lower enclosure of the laptop and serves as a replacement chassis part when that component needs to be replaced.

HP’s service guide lists this part number for the 14-inch base enclosure and gives a separate part number for the 15-inch version. A specialist listing identifies it as the bottom chassis case for the HP ProBook 640 G2. This makes the item useful for repair work involving that specific chassis component.
