Lenovo ThinkPad T480s USB Port Switch Board

This USB port switch board carries part numbers ET481 and NS-B472 and is built for the Lenovo ThinkPad T480s. It integrates the USB ports, SD card interface, audio connections and earphone jack into a single internal module. Technicians replacing a damaged I/O daughterboard will find the correct fit for this model. The part restores the full complement of side-panel connections without requiring a full chassis swap.

OEM Build Quality for Reliable Daily Use

The board is manufactured to Lenovo specifications so the solder joints and connector retention match the original assembly. Precise mounting holes align with the T480s chassis standoffs, preventing flex when cables are inserted or removed. Gold-plated contact fingers on the board-to-board connector resist oxidation through repeated thermal cycles. This ensures stable data and audio signals during everyday docking, peripheral changes and headset use.
