Genuine Dell Palmrest Assembly

This genuine Dell palmrest assembly includes the touchpad, mouse buttons, power button board and ribbon cables. It is a direct replacement for the original chassis section on Inspiron 14R 5421 and Inspiron 14 3421 laptops. The part arrives new and ready to install. ||

Replaces Worn or Damaged Top Case

Fit this assembly when the existing palmrest is cracked, the touchpad has failed or the power button no longer responds. It restores the original feel and function without requiring a full chassis swap. The jump is worth it when only the top section is faulty and the mainboard remains sound. ||

Verify Model Number Before Ordering

Confirm the laptop service tag or bottom-case sticker reads Inspiron 14R 5421 or Inspiron 14 3421. The Dell part number XRRMM must match the original component. No other models are supported by this assembly.

Questions about this item

Does the XRRMM palmrest assembly match the mounting points of the Inspiron 14 3421 chassis?

Which ribbon cables must be reconnected during installation of this palmrest?

Will the touchpad ribbon cable on the XRRMM assembly need periodic replacement?

The ribbon cables are integrated into the assembly; they are replaced only if the touchpad or power button fails, not on a scheduled basis.
