Genuine Dell OEM USB Port Board

This is a genuine Dell OEM single USB port circuit board designed as a direct replacement for the Dell Inspiron 1720, 1721, and Vostro 1700 laptop models. It restores a damaged or non-functional USB port on these specific systems. The board carries part numbers DAGM2TB18D0, DAGM2TB18D2, and TX631 for identification.

Verify Laptop Model and Connector

Confirm your laptop is an Inspiron 1720, Inspiron 1721, or Vostro 1700 before ordering, as this board is not compatible with other Dell models. Check that the existing USB port circuit board matches the physical layout and connector orientation shown in the product images. Ensure the motherboard header for this daughterboard is undamaged.

Fits Inside Compatible Laptop Chassis

This circuit board installs internally within the chassis of the supported Inspiron and Vostro laptops, connecting directly to the motherboard via its integrated header. Replacing the faulty board restores full USB connectivity without requiring a full motherboard swap. It frees up the system for peripheral use once the specific port is repaired.

Questions about this item

What is included with the USB port circuit board and do I need any extra cables?

The listing supplies only the single USB port circuit board shown in the photograph. No additional cables, screws or mounting brackets are included, so reuse the original hardware from the laptop.

How do I choose the correct version for my laptop among the compatible models listed?

The board fits the Dell Inspiron 1720, Inspiron 1721 and Vostro 1700. Match the model number on the bottom case of your laptop to one of those three before ordering.

What does the single USB port provide once the board is installed in the machine?

After installation the board restores one functional USB port on the side of the laptop, allowing standard USB peripherals such as mice, flash drives or external keyboards to connect again.
