Genuine Dell OEM Palmrest Assembly

This genuine Dell OEM palmrest assembly fits Latitude 7290 and 7390 laptops. It includes the touchpad module, smart card reader, mouse buttons, LED indicator and USH junction board. The part replaces a worn or damaged upper chassis section. Buyers restoring either model to factory specification will find all modules pre-assembled.

Replaces cracked or unresponsive palmrests

The assembly swaps out a palmrest with a failed touchpad, broken smart-card reader or missing buttons. It is worth fitting when the existing chassis is physically damaged or the integrated modules no longer register input. The repair restores full pointing, clicking and smart-card function without board-level work. Builders needing a different keyboard layout or additional ports cannot use this part.

Fits Latitude 7290 and 7390 chassis

Installation requires a compatible Latitude 7290 or 7390 lower case and the existing keyboard. The assembly frees the technician from sourcing the touchpad, card reader, buttons, LED and junction board separately. No other laptop models are supported by this part number.

Questions about this item

Does this palmrest assembly align with the existing screw holes on a Latitude 7290 chassis?

Yes, the assembly is built to the original Dell specifications for the Latitude 7290 and 7390, so the mounting points match the factory chassis exactly.

Which ribbon cables must be reconnected during installation, and which step is most often missed?

Reconnect the touchpad ribbon (2W4VC), smart-card reader ribbon (GD8W8), power-button/LED cable (9XWHC) and the USH junction board; the USH board connector is the step most often overlooked.

If the smart-card reader stops reading badges, which module do I replace and what is its part number?

Swap the smart-card reader module only; its Dell part number is GD8W8 and it lifts out of the palmrest after removing the securing screws.
