Genuine Dell Vostro 3700 Audio Board

This genuine Dell OEM circuit board carries the part number MF94N and fits the Vostro 3700 laptop. It provides the external audio input and output ports, the wireless on-off switch, and the internal Bluetooth connector. The component is supplied new and matches the unit shown in the product images. It restores front-panel sound and wireless control when the original board has failed.

Who this suits and who should look elsewhere

This part is for technicians or owners repairing a Dell Vostro 3700 that has lost audio jacks, the wireless toggle, or Bluetooth connectivity. It is not suitable for any other laptop model, including other Vostro series units, because the connector layout and mounting points are specific to the 3700 chassis. Buyers needing a replacement for a different Dell notebook must source the correct board for that machine.

Critical compatibility detail — Dell part number

The sole specification that confirms fitment is the Dell part number MF94N printed on the board. Only the Vostro 3700 is listed as compatible in the manufacturer data, so the MPN must match exactly before installation. No other identifiers or cross-references are supplied, so verify the number on the original part prior to purchase.

Questions about this item

What physical space does the Vostro 3700 audio ports circuit board MF94N occupy inside the chassis?

It fits the dedicated daughter-board cavity on the Vostro 3700 motherboard tray and aligns with the external cut-outs for the headphone jack, microphone jack, wireless switch and Bluetooth connector.

How is the MF94N board installed, and which step is often missed?

Remove the palm-rest assembly, disconnect the ribbon cable from the mainboard, swap the board, then reconnect the ribbon and the separate Bluetooth cable — the Bluetooth connector is frequently left unplugged.

When should the audio ports circuit board MF94N be replaced?

Replace it when the headphone or microphone jacks become intermittent, the wireless toggle stops switching radios, or the Bluetooth module is no longer detected by the Vostro 3700.
