Dell Inspiron 2-in-1 I/O Board

This genuine Dell I/O circuit board provides a USB port, an SD card reader slot and a WLAN card slot for select Inspiron 2-in-1 laptops. It carries Dell part number 1379X and is supplied new as an original equipment replacement. The board restores connectivity functions on supported models.

Fits Inspiron 13 15 and 17 2-in-1 models listed

Compatible systems include the Inspiron 13 7378, Inspiron 15 7569 and 7579, and Inspiron 17 7773, 7778 and 7779 2-in-1 laptops. Buyers whose laptop is not among these exact model numbers should look for a different I/O board because the connector layout and mounting points vary by platform.

Dell part number 1379X confirms the correct board

Match the 1379X marking on the original board to ensure compatibility before ordering. Alternate references such as Starlord13_B I/O and Y7TGP refer to the same part. Using the part number avoids fitting a board with a different port arrangement or flex cable routing.

Questions about this item

Will the SD card slot on this 1379X board keep up with continuous large-file transfers?

The board provides one SD card reader slot and one USB port; sustained throughput will depend on the card speed class and the laptop's internal USB controller.

Does the 1379X daughterboard run hot or draw extra power when the WLAN card and SD reader are both active all day?

The board simply routes signals for the WLAN card slot, USB port and SD reader; it adds no active cooling or power regulation of its own.

My Inspiron 15 7569 is missing the IO board entirely — what other parts must already be in the chassis for this 1379X to function?

You need the existing WLAN card, antenna cables, motherboard header connection and chassis mounting points already present in the 7569 or 7579.
