Genuine Dell OEM replacement cable

This genuine Dell OEM cable connects the USB IO board to the motherboard inside Inspiron 11 3135 and 3137 laptops. It carries Dell part number YP4N5 and matches the ZM3 FFC IO reference. The part is supplied new and is intended for component-level repair of the USB interface.

Repair fit and system integration

The cable slots directly between the USB IO board and the mainboard, restoring the physical link for external USB ports. No soldering or firmware work is required, and the flexible flat design follows the original routing inside the chassis. Installers should verify the connector orientation before seating the cable to avoid pin damage.

What the part restores

Fitting this cable re-enables the laptop’s built-in USB ports for peripherals such as mice, keyboards and storage devices. It does not add extra ports, change USB signalling standards or include mounting hardware beyond the cable itself. The repair returns the machine to its factory I/O configuration.

Questions about this item

Does the YP4N5 cable limit data or power delivery under sustained use?

The cable simply carries the USB board signals to the motherboard and has no active circuitry that would throttle throughput.

Does the cable generate noticeable heat or noise when the laptop runs all day?

It is a passive flat-flex interconnect, so it produces no heat of its own and makes no sound.

Must the laptop already have a working USB IO board for this cable to function?

Yes — the cable connects that board to the motherboard on Inspiron 11 3135 and 3137 models.
