Genuine Dell OEM Latitude E7440 Ribbon Cable RF1X0

This genuine Dell OEM ribbon cable connects the power button board with USB and audio ports to the motherboard in Latitude E7440 laptops. It carries the Dell part number RF1X0 and matches the alternative references VAUA0 and LF-9591P. The part is supplied new and matches the component shown in the product imagery.

Passive flex circuit with no active cooling

As a passive flex circuit, the cable draws no power and generates no heat or noise during operation. It simply routes signals between the I/O daughterboard and the main system board. No thermal management, fan control or external power connection is required for this component to function.

Direct replacement restores front I/O

Installing this cable restores the connection between the motherboard and the USB, audio and power button board. It resolves failures where front ports or the power switch become unresponsive due to a damaged or worn original cable. No software, drivers or additional accessories are included or required for the repair.

Questions about this item

How do I route the RF1X0 ribbon cable through the hinge area when replacing it on a Latitude E7440?

Remove the bottom case and keyboard deck, thread the flat cable along the original path beside the hinge, seat both ZIF connectors fully, then reinstall the deck without pinching the ribbon.

What maintenance does the USB audio databoard cable need over time?

No routine maintenance is required; if the USB ports or audio jack become intermittent, the ribbon itself must be replaced as a unit.

What failure appears first when the RF1X0 cable is flexed repeatedly during lid movement?

The copper traces inside the ribbon develop fatigue cracks, causing the power button or USB audio ports to stop responding.
