Dell Vostro 3400 Palmrest Assembly JXX8K

This genuine Dell OEM replacement palmrest touchpad assembly is designed specifically for the Vostro 3400 laptop. It restores full touchpad, media button, LED indicator and power button functionality in a single integrated unit. The part arrives new and ready for installation by repair technicians or experienced laptop owners.

Installation requires partial laptop disassembly

Replacing the palmrest involves removing the bottom case, battery, keyboard deck and associated flex cables before swapping the assembly. The most common issue is damaging the fragile ribbon cables or misaligning the power button board connector during reassembly. Patience and an anti-static workspace prevent bent pins and intermittent button faults.

Verify your exact model before ordering

This assembly fits only the Dell Vostro 3400 series; other Vostro or Inspiron models use different part numbers and mounting points. Confirm the service tag or chassis sticker reads Vostro 3400 to avoid receiving a part that will not align with your screw holes or cable routing.
