Genuine Dell OEM Palmrest Ribbon Cable
This is a genuine Dell OEM ribbon cable that connects the palmrest USH junction board to the motherboard. It is designed specifically for the Precision 7670 laptop and carries part number A2193E. Buyers who need a replacement for a different Dell model or a non-Dell laptop cannot use this part.
Passive Connection With No Power Draw
The cable is a passive flexible circuit that carries signals between the palmrest board and the mainboard. It draws no power, generates no heat and produces no audible noise during normal operation. There are no active components that would affect thermals or acoustics.
Precision 7670 Compatibility Is The Deciding Factor
This ribbon cable fits only the Dell Precision 7670 according to the manufacturer compatibility list. Alternate part numbers HDC50 and NBX0002ZP00 refer to the same component. If your service tag or chassis model differs, this cable will not connect correctly.

Questions about this item
How is the A2193E ribbon cable installed in the Precision 7670, and which connector orientation is commonly reversed?
The cable links the palmrest junction board to the motherboard; align the blue stiffener tab toward the board edge before locking the ZIF latch, otherwise the USH module will not enumerate.
What maintenance or replacement will the A2193E cable need over the laptop's life?
No scheduled maintenance; replace only if the USH fingerprint reader or smart-card slot becomes intermittent, indicating conductor fatigue or ZIF contact oxidation.
What limit appears first on the A2193E cable under sustained daily flexing of the palmrest?
The fine-pitch conductors can develop micro-cracks after repeated hinge cycles, causing USH signal drop-outs before the insulation or shield shows wear.
