Compatible Latitude 7490 Palmrest Assembly

This genuine Dell palmrest assembly is built for the Latitude 7490 laptop. It integrates the touchpad, mouse buttons, LED indicator light and a smart card reader into one replaceable unit. IT technicians and repair specialists use it to restore full input and authentication functions.

Replaces Damaged Palmrest with Integrated Reader

The assembly swaps out a cracked, worn or malfunctioning palmrest that has lost touchpad response or smart card capability. The jump is worth it when both the pointing device and the contact reader fail together, avoiding separate part orders and repeated teardowns.

Sustains Daily Authentication and Navigation

Under continuous office use the touchpad tracks reliably and the smart card reader maintains consistent contact reads over long sessions. The included USH junction board and indicator cable keep the secure-login chain stable without intermittent disconnects.
