Use this guide to replace the USB board (aka "connector board") in your HP EliteBook 845 G9 laptop.
The connector board is on the same side of the laptop as the audio jack. It includes the SIM card slot and one USB‑A port.
If either the USB‑A port or SIM card slot are broken or have a loose connection, you may need to replace the connector board.
Before replacing the connector board, test the port with a different cable to make sure the problem is with the port itself and not the cable.
