Optical Drive Connector Board

The HP 840746-001 optical drive connector board is a replacement part for select HP notebook configurations that combine an optical drive with a serial port. The service guide identifies this exact part number for that configuration.

The listing specifies RJ-11 and RS-232 connectors. This distinguishes it from part 840745-001, which the guide assigns to products with an optical drive but without the stated serial-port requirement.

Use it as the connector board for the supported optical-drive and serial-port configuration. The available documentation does not specify package contents.
