Dell Latitude E6400 Palmrest Touchpad Assembly TN281

Genuine Dell Latitude E6400 palmrest assembly

This genuine Dell replacement palmrest and touchpad assembly is built for the Latitude E6400 laptop. It integrates the touchpad circuitry, left and right speakers, a smart-card slot and a contactless smart-card reader. The spring latch is included, while the power-button board and right speaker grill are not.

Thermals noise and power draw

As a passive mechanical part, the assembly produces no heat, emits no noise and draws no power during normal laptop operation. It simply replaces the original chassis section without adding any active components.

Behaviour under sustained load

Because the unit contains no electronics that generate heat, its physical properties do not change during prolonged use. The touchpad, speakers and smart-card reader continue to function exactly as they do in short bursts.
