Fingerprint sensor assembly

HP L77268-001 fingerprint sensor assembly is a service part for the HP ProBook 450 G7 notebook. It provides the fingerprint sensing component used for biometric sign-in, giving the computer a fingerprint based way to authenticate its user.

The assembly is described as a sensor board with a cable connection to a ZIF connector. The HP guide lists the sensor cable separately as part L45087-001, so the assembly and cable are distinct service parts. The distributor listing specifies that this assembly includes the sensor and conductive tape and is integrated into the system board.

HP’s service guide documents replacement of the sensor assembly. The procedure involves access inside the notebook and disconnecting the cable from the sensor board. This part is intended for the ProBook 450 G7 configuration that uses a fingerprint sensor.
