Genuine Dell Latitude E6440 Palmrest Assembly
This genuine Dell palmrest assembly is built as a direct replacement for the Latitude E6440 notebook. It integrates the touchpad, mouse buttons, power button board and volume controls into a single module. The unit also includes a fingerprint reader and a contactless smart card reader for secure authentication. It is intended for technicians or owners repairing a damaged or worn chassis.
Integrated Input and Security Modules
The assembly combines daily input devices with biometric and smart-card security hardware in one chassis section. All included boards and the fingerprint sensor are original Dell components matched to the E6440 layout. No separate driver installation is required beyond the standard Dell support package. The design maintains the factory fit and finish for the supported model.
Dell Part Number V7MXM Compatibility
The decisive specification is the Dell part number V7MXM, which confirms fitment solely for the Latitude E6440. Buyers needing a palmrest for any other Dell series or a different manufacturer will find this part incompatible. Verify the service tag or existing part label before ordering to avoid mismatched mounting points or cable connectors.

Questions about this item
How do I connect the fingerprint reader and smart-card reader cables when installing the palmrest assembly?
Route the fingerprint reader flex and the contactless smart-card reader cable through the chassis opening, then seat each connector fully into the junction board 3MW70 before locking the palmrest screws.
Which boards in this assembly are most likely to need replacement after extended use?
The touchpad A12C01, mouse-button board A131CE, power-button board, volume-button board and the smart-card reader cage 2P86N are the serviceable modules that can be swapped individually.
What is the first limitation I will hit if I use the fingerprint reader continuously?
The sensor is designed for intermittent authentication; sustained rapid scans will exceed its duty cycle and force a cool-down pause.
