Introduction
Follow this guide to replace the front USB and power button board in your Valve Steam Machine (2026).
The front board includes two USB-A ports as well as the power button, which are all soldered to the board. To replace any one of these ports, it's easiest to replace the entire board.
If the front ports in your Steam Machine are loose or won't connect, you may need to replace the board. Replacing the front board can also fix issues with the power button sticking or not working.
Before starting this repair, clean the ports out first and test them with different cables to confirm the problem is with the ports themselves.
What you need
-
-
-
Power down your Steam Machine and disconnect the power cable.
-
Unplug any remaining cables or accessories from all ports.
