Palmrest for Latitude 7490 Dual Point
This genuine Dell palmrest assembly fits the Latitude 7490 with a dual pointing layout. It includes the touchpad module, mouse buttons and LED indicator cable. The part matches Dell part numbers TDYRC and NH8HX. It is intended for technicians or owners repairing a worn or damaged input surface.
Not for Smart Card models or single pointing layouts
This assembly lacks the smart card reader cutout, so it will not fit Latitude 7490 units equipped with that option. It also suits only the dual pointing configuration with a centre stick and two button sets. Buyers whose laptop uses a single pointing layout or includes a smart card reader need a different part.
Dual pointing layout without smart card support
The defining specification is the dual pointing layout combined with the absence of a smart card reader aperture. Verify that the original palmrest carries part number TDYRC or NH8HX and shows two sets of mouse buttons before ordering.
