Palmrest for Latitude 7490

This genuine Dell palmrest assembly fits the Latitude 7490 laptop. It arrives new and includes the integrated touchpad module, mouse buttons and a smart card reader. Technicians or owners repairing a damaged chassis can restore full input and security functions with this single part.

Passive thermal profile

The assembly contains no active cooling, so it adds no fan noise or power draw to the system. Heat from the touchpad electronics dissipates through the surrounding chassis during normal typing and pointing use. No additional thermal management is required after installation.

Metal-reinforced frame with integrated modules

A rigid internal frame resists flex when the laptop is carried or used on uneven surfaces. The smart card reader, touchpad, button board, LED indicator and USH junction board are pre-fitted, reducing reassembly time. Alignment posts match the Latitude 7490 screw pattern for a secure, rattle-free fit.

Questions about this item

How do I install the palmrest assembly on my Latitude 7490, and which step is often missed?

Remove the battery first, then disconnect the touchpad cable (78RRW) and smart-card reader cable (T54GY) before lifting the old palmrest; the step most people skip is reseating the LED indicator cable (Y81KR) and the USH junction board (CAZ20) under the new assembly.

Which parts of this FJN2P assembly will need replacement after heavy use?

The touchpad module (78RRW) and mouse buttons (XKYX9) wear first; the smart-card reader module (T54GY) and LED indicator (Y81KR) rarely fail but can be swapped individually if needed.

What is the first limitation that appears during sustained typing and clicking?

The click mechanism on the mouse buttons (XKYX9) develops uneven travel before the touchpad sensor (78RRW) or smart-card reader (T54GY) shows any degradation.
