Genuine Dell Vostro 3420 palmrest assembly

This genuine Dell OEM palmrest assembly includes a backlit keyboard and discrete keyboard bracket. It is designed specifically for Vostro 3420 laptops equipped with discrete Nvidia graphics, an optional USB-C port, and WLAN antennas located in the display assembly. The part number is V4T7G.

Configuration-specific compatibility

This assembly fits only Vostro 3420 systems matching the exact hardware configuration described. Units with integrated graphics, without the USB-C port, or with antennas placed elsewhere in the chassis require a different part number. Installing this part on a mismatched configuration will result in physical or functional incompatibility.

Discrete graphics and USB-C requirement

The defining specification is the requirement for discrete Nvidia graphics combined with the optional USB-C port and display-mounted antennas. Buyers must verify their Vostro 3420 matches this exact configuration before ordering. Systems lacking discrete graphics or the USB-C port cannot use this assembly.

Questions about this item

Does the backlit keyboard on this Vostro 3420 palmrest assembly draw enough power to affect battery life during all-day use?

The backlit keyboard is a standard low-power LED assembly; its draw is negligible compared to the discrete Nvidia graphics and CPU, so it will not materially change battery runtime.

Which existing laptop components must I already own for this V4T7G palmrest to install and function correctly?

You need a Vostro 3420 chassis built for discrete Nvidia graphics, the optional USB-C port, and WLAN antennas routed in the display assembly — this part matches only that configuration.

Will this V4T7G palmrest fit a Vostro 3420 that originally shipped with integrated graphics and no USB-C port?

No — the part number V4T7G is keyed for models with discrete Nvidia graphics, the USB-C cut-out (F9X43) and display-mounted antennas; other 3420 variants use different palmrests.
