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.
