Repair technicians replacing a damaged port assembly

This board suits technicians restoring full USB and SD connectivity on a Dell Inspiron 15z 5523. It is not for users needing additional ports beyond the two USB and single SD interfaces provided. Buyers with other laptop models or motherboard revisions should look elsewhere as compatibility is limited to the specified system.

Two USB ports and one SD card slot

The assembly comfortably handles standard peripheral connections and memory card transfers for the supported laptop. It runs out when more than two USB devices or concurrent card readers are required. The part replaces the original IO board to restore factory I/O capability on the 5523 platform.

Questions about this item

Does this board fit my Inspiron 15z 5523 without any other parts?

It is a direct replacement IO board for the Inspiron 15z 5523; you only need the existing motherboard connector and the original mounting screws.

Will the two USB ports and SD slot on this board work with my older USB 2.0 flash drives and SDHC cards?

The ports are backward compatible, so legacy USB 2.0 devices and standard SDHC cards will function normally when the board is installed.

How can I confirm the board is working after I install it?

Plug in a known-good USB device and insert an SD card; both should appear in File Explorer and Device Manager without errors.
