Genuine Dell Palmrest for Vostro 1440

This replacement assembly fits Dell Vostro 1440, Inspiron M4040, Inspiron N4050 and Inspiron 3420 laptops. It restores the original palmrest, touchpad and power-button functions using Dell part number GN7T3. The part is supplied new and ready for installation.

Installation Requires Partial Disassembly

Fitting the assembly involves removing the keyboard and top cover to access the palmrest mounting points. The touchpad and power-button ribbon cables are delicate; misalignment or excessive force when seating the connectors is the most common cause of post-install failure. Take photographs of the cable routing before disconnecting the original unit.

Verify Your Exact Model Number Before Ordering

This palmrest is compatible only with the four model families listed in the compatibility data. Other Vostro or Inspiron chassis, even visually similar ones, use different mounting points and ribbon-cable layouts. Confirm the service tag or bottom-case sticker matches one of the supported models to avoid receiving a part that will not fit.
