Genuine Dell OEM replacement part
This genuine Dell OEM ribbon cable carries part number 94MJV and fits the Chromebook 3120 2-in-1 model. It connects the right-side USB IO board to the motherboard using a 50-pin interface. The cable is one of two required links for the IO board assembly.
Passive component with no active cooling
As a passive flex cable it draws no power, generates no heat and produces no audible noise during operation. Normal use places no thermal load on the system and requires no additional cooling consideration. Installation simply restores the original electrical path between board and motherboard.
Restores right-side USB connectivity
Replacing a damaged cable returns full function to the right-side USB ports on the 2-in-1 chassis. No software, drivers or configuration changes are needed after fitting the part. The repair is limited to this specific 50-pin connection; the second IO-board cable is not included.

Questions about this item
How is the 50-pin ribbon cable installed on the Chromebook 3120 2-in-1, and what step is often missed?
Disconnect the battery, remove the bottom case, detach the old cable from the motherboard and right-side USB IO board, then connect the new 94MJV cable to both ZIF connectors and lock the retention tabs before reassembly.
What maintenance or replacement will the 50-pin ribbon cable need later?
The cable itself requires no scheduled maintenance; replace it only if the right-side USB ports stop working or the connector latches break during a future repair.
What limit appears first on the 50-pin ribbon cable under sustained use?
Repeated flexing from opening the 2-in-1 hinge can fatigue the conductors, leading to intermittent USB connectivity on the right side before the cable fails completely.
