Genuine Dell Latitude 7490 Palmrest Assembly

This genuine Dell palmrest assembly is built for the Latitude 7490 laptop with an EMEA dual pointing keyboard layout. It integrates the touchpad sensor module, status lights board and lower mouse buttons into one replacement unit. The part carries Dell part number 3FY87 and is intended for technicians or owners repairing a damaged palmrest.

Fits Latitude 7490 EMEA dual point models only

Installation requires a Latitude 7490 chassis that uses the EMEA dual pointing keyboard layout; the assembly will not support US-English keyboards. The package includes the palmrest, touchpad sensor module 78RRW, status lights board Y81KR and mouse button board XKYX9. No additional cables or brackets are mentioned in the data.

Replaces a cracked or malfunctioning original

The jump is worth it when the existing palmrest is physically damaged, the touchpad fails or the status lights stop working. It restores the original factory fit and dual pointing function. Buyers needing a US-English layout or a different laptop model cannot use this assembly.

Questions about this item

What is the first component that limits sustained typing comfort on this palmrest?

The lower left and right mouse buttons (XKYX9) are the primary contact points that determine long-term tactile feel during extended typing sessions.

Does the touchpad sensor module generate noticeable heat or noise during all-day use?

The 78RRW touchpad sensor module is a passive capacitive component with no moving parts, so it produces no audible noise and negligible heat under continuous operation.

Which existing laptop parts must I already own for this assembly to function?

You need a Dell Latitude 7490 chassis with an EMEA dual-pointing keyboard layout; the palmrest will not fit US-English keyboards and requires the matching status lights board (Y81KR) and touchpad cable routing already present in that model.
