Dell Vostro V131 Right-Side IO Board

This genuine Dell OEM circuit board provides the right-side input and output ports for the Vostro V131 laptop. It integrates USB, audio, VGA, and RJ-45 network connectivity onto a single replacement module. The part arrives new and matches the component originally installed by the manufacturer.

Fits Vostro V131 Chassis Directly

The board slots into the existing right-side opening of the Vostro V131 without requiring case modifications or adapter cables. It restores the factory port layout so external displays, wired networks, audio devices, and USB peripherals connect exactly as designed. Installation reuses the laptop's native mounting points and ribbon connectors.

This unit corresponds to Dell part number RX7N5 and the listed alternate numbers including 554ND02001G14101154KS1B. Using the correct OEM board ensures the port alignment, signal routing, and firmware handshake match the system BIOS expectations. No driver discs or configuration utilities are bundled because the laptop's existing software recognises the hardware automatically.

Questions about this item

What is the first limit that appears when the USB, VGA, audio and RJ-45 ports on this RX7N5 board run under sustained load?

The board carries four different interfaces — USB, VGA, audio and RJ-45 — and each has its own bandwidth or current ceiling; the first one reached depends on which ports are active simultaneously.

How much noise, heat or power does this right-side IO board add when the Vostro V131 runs all day?

The board is a passive circuit with no fan or active components, so it adds no audible noise and negligible heat or power draw beyond the signals passing through its ports.

What must I already own for this RX7N5 board to work in my machine?

You need a Dell Vostro V131 chassis and the matching left-side board, because this part only provides the right-side USB, VGA, audio and RJ-45 connections for that specific model.
