0NVR0X LF-F211P IO Board Flex Cable, OEM Replacement Connector Ribbon Cable for Dell XPS 9575 & Precision 5530 2-in-1 Laptop

This LF-F211P IO board flat ribbon cable with Dell OEM part number CN-0NVR0X is a dedicated internal replacement wiring exclusively designed for Dell XPS 9575 and Precision 5530 2-in-1 convertible laptops. It acts as the core signal bridge between the laptop main motherboard and the side IO small daughter board that carries external USB, audio jack and peripheral ports.

Many common faults such as undetected USB devices, no headphone audio output and unresponsive side ports are caused by aging, cracked or broken original IO flex cable from frequent folding of the 2-in-1 hinge. This replacement cable adopts the same pin definition, circuit layout and soft FPC flat material as factory original parts, ensuring seamless plug-and-match installation without modification.

All gold-plated contact terminals maintain stable conductivity, effectively avoiding signal loss, intermittent connection and port malfunction during long-term daily use. The cable features pre-shaped bending lines that strictly follow the internal chassis wiring route of XPS 9575 and Precision 5530, which will not be squeezed or torn after assembly.

No soldering operation is required for replacement; users only need to open the laptop shell, unplug the damaged old cable via ZIF lock connectors and install this new ribbon cable. Each cable undergoes strict signal continuity testing before shipment to guarantee zero defect rate. It is an essential maintenance spare part for notebook repair stores and individual users to restore full functions of Dell 2-in-1 workstation side IO interfaces.
