Dell Latitude 7490 Palmrest Assembly

This genuine Dell palmrest assembly replaces the upper chassis section on Latitude 7490 laptops. It integrates the touchpad module and dual pointing-stick buttons for systems configured without a smart-card reader. The part arrives new and ready for installation by a qualified technician.

Suits owners repairing a 7490

Ideal for technicians restoring a Latitude 7490 that uses both a centre pointing stick and two sets of mouse buttons. Not suitable for 7490 models equipped with a smart-card reader or a single pointing configuration. Buyers needing a palmrest with smart-card support should look elsewhere.

Verify the dual-point layout before ordering

Confirm the laptop carries the dual pointing-stick and button arrangement and lacks a smart-card slot. Cross-reference the Dell part numbers TDYRC or NH8HX with the service tag or existing palmrest sticker. Professional fitting is recommended to avoid damaging the fragile ribbon cables.
