Dell Vostro A840 Palmrest Assembly J997H

This genuine Dell OEM palmrest touchpad assembly is built for the Vostro A840 laptop. It arrives new and includes the integrated power button circuit board, LEDs, touchpad surface and mouse buttons in one piece. The part is intended for technicians or owners repairing a damaged upper chassis on this specific model.

Replaces a cracked or malfunctioning palmrest

The upgrade is worth it when the existing assembly has physical damage, unresponsive buttons or a failed touchpad sensor. It is not suited for other Dell series or for buyers who need a standalone touchpad module without the surrounding chassis and power-button circuitry.

Questions about this item

Will the J997H palmrest assembly align with the screw posts on a Vostro 840 chassis?

The J997H assembly is built for the Vostro 840, so its mounting points and screw posts match the original chassis layout exactly.

Which cables must be reconnected after seating the palmrest, and which one is most often missed?

Reconnect the touchpad ribbon, the power-button board cable and the mouse-button flex; the power-button board cable is the one most often overlooked during reassembly.
