Genuine Dell Vostro 3420 palmrest assembly

This genuine Dell OEM palmrest assembly fits the Vostro 3420 laptop when configured with integrated Intel graphics, a USB-C port and WLAN antennas routed to the display assembly. It is intended for owners or repair technicians replacing a damaged or worn top case on that specific hardware variant. The part number is 4RRNY.

Backlit US International keyboard included

The assembly ships with a backlit US International keyboard and the UMA keyboard bracket DKJJV already fitted. It provides the standard typing layout and illumination for low-light work. Buyers whose Vostro 3420 uses discrete graphics, lacks USB-C or places the antennas in the palmrest cannot use this part.

OEM fit with USB-C cutout and no antenna holes

The palmrest moulding matches the factory chassis, including the USB-C port opening and the absence of WLAN antenna apertures. Alignment posts and screw bosses line up with the existing motherboard and bottom case. Installers should verify their system matches the Intel-graphics, USB-C, display-antenna configuration before ordering.
