Genuine Dell Vostro 3420 Palmrest Assembly

This is a genuine Dell OEM palmrest keyboard assembly for the Vostro 3420 laptop. It includes the palmrest, a non-backlit keyboard, discrete keyboard bracket and integrated WLAN antennas. The part carries Dell part number 29G0Y and is supplied new. It is intended for repair technicians or owners replacing a damaged upper chassis.

For Vostro 3420 Models

This assembly fits Vostro 3420 units equipped with discrete Nvidia graphics, the optional USB-C port and WLAN antennas routed through the palmrest. It will not fit Vostro 3420 configurations that use integrated graphics, lack the USB-C port or place the antennas in the display lid. Buyers needing a backlit keyboard or a different antenna layout should look for the corresponding alternate part number.

Installation Requires Full Upper Chassis Replacement

Replacing this assembly involves removing the bottom case, battery, motherboard, display hinges and all internal cabling to swap the entire upper chassis. The integrated antennas and USB-C cutout must align with the specific motherboard variant. Common issues include ordering the wrong palmrest for the graphics or antenna configuration, damaging fragile antenna cables during routing, and failing to reconnect the keyboard ribbon or USB-C flex correctly.
