Genuine Dell Precision 7540 Palmrest Assembly

This genuine Dell OEM palmrest assembly is built for the Precision 7540 mobile workstation. It integrates the touchpad, fingerprint reader, smart card reader, NFC/RFID reader, power button board, mouse buttons and the required USH junction board with cables. The part arrives new and ready for installation.

Dell Part Number 7KCXT Confirms Fit

The critical specification is the Dell part number 7KCXT, also referenced as YJTD6, which guarantees compatibility with the Precision 7540 chassis. Buyers who need a palmrest for a different Dell model or a non-Dell laptop cannot use this assembly.

Bundled Modules Restore Full Input

The included touchpad module CPV25, fingerprint reader M22F7, smart card reader MW78P and NFC/RFID reader 549MC replace every front-facing sensor and button in a single step. Builders who only need a bare palmrest without these integrated components should look elsewhere.

Questions about this item

How does the fingerprint reader module integrate once the palmrest is installed in a Precision 7540?

The M22F7 fingerprint reader and its A19P21 cable are pre-assembled on the palmrest, so they connect directly to the USH junction board and USH cable EDA50 NBX0002H200 without extra steps.

What interface does the CPV25 touchpad use and what does that limit in practice?

The CPV25 touchpad connects through the USH junction board and USH cable EDA50 NBX0002H200, so its data path is capped by that internal USH link.

Which mounting points and cables must align when fitting this palmrest on a Precision 7540?

The assembly includes left and right mouse buttons VNN84, power button board HXJWN with PB cable RYT1M, smart card reader MW78P and NFC reader 549MC, all pre-mounted to match the 7540 chassis screw locations.
