Dell Latitude D420 Biometric Palmrest

This genuine Dell replacement palmrest assembly fits the Latitude D420 notebook and integrates a fingerprint reader for biometric login. The part carries Dell part number KG117 and arrives in new condition ready for installation. It restores both pointing and security functions in a single module.

Replaces a worn or damaged original palmrest

The upgrade is worthwhile when the existing touchpad fails, the fingerprint sensor stops enrolling prints, or the chassis shows cracks around the palm area. Buyers who need a backlit keyboard, a larger trackpad or a modern Windows Hello camera will not find those features here.

Questions about this item

Will the KG117 palmrest assembly fit my Latitude D420 chassis?

The KG117 is the Dell part number for the Latitude D420 biometric palmrest, so it matches the original mounting points and cable routing for that model.

Which cable connectors must be seated during installation, and which one is most often missed?

Connect both the touchpad ribbon and the fingerprint reader ribbon to the system board; the fingerprint reader cable is shorter and is the one most often left unplugged.
