Genuine Dell OEM palmrest assembly with fingerprint reader, touchpad, smart-card reader and power-button board for Precision 7530 laptops
This genuine Dell OEM palmrest assembly is built for the Precision 7530 mobile workstation. It arrives new and includes the touchpad module, fingerprint reader, smart card reader, power button board and mouse buttons. Technicians repairing a damaged chassis or upgrading a worn palm area receive all integrated input components in one matched set.
The assembly contains no active cooling, fans or electronics that draw power beyond the fingerprint reader and touchpad circuitry already accounted for by the host laptop. Normal operation adds no audible noise and imposes no additional thermal load on the system. Power consumption remains identical to the original factory configuration.
The package supplies the CPV25 touchpad module, C7TYX smart card reader, XY6H2 USH junction board, NBX0002AC00 USH cable, A178H3 fingerprint reader cable, XFJJF mouse buttons, MWF2P power button board and Y48T7 power button cable. Each sub-module is factory-fitted so the installer does not need to source or align individual cables and boards separately.

Remove the bottom cover and battery, disconnect the USH cable NBX0002AC00, fingerprint cable A178H3, power button cable Y48T7 and touchpad cable CPV25, then lift the old assembly; the step most often missed is reconnecting the USH junction board XY6H2 cable before seating the new palmrest.
The fingerprint reader module and touchpad CPV25 are integrated; if either fails the whole palmrest assembly must be replaced, while the smart card reader C7TYX and mouse buttons XFJJF can be swapped individually if they wear out.
The fingerprint reader cable A178H3 and USH cable NBX0002AC00 flex with every lid cycle, so connector fatigue on those cables typically shows up before the touchpad CPV25 or power button board MWF2P.
