5. Make sure that all three power supply connections are firm.
6. Turn on the console, and check the light on the power supply.

Check the light on your power supply unit

The light on your power supply unit can give you a clue as to whether its working properly:

Solid white or solid orange light: Your power supply is working. If your console wont turn on, see Troubleshooting a blank TV or monitor with your Xbox One.

Power supply displays no light: Your power supply may need to be replaced. Try the following solutions first:

1. Plug your consoles power supply into a different electrical outlet. Do not use a surge protector.
2. If the unit is still not lit up, unplug the power supply and let it cool for 30 minutes. Then plug it back into the outlet.

Note If you are able to borrow a power supply from another Xbox One unit (friend, relative, etc.), try it on your own unit to see if it makes a difference. If so, then you can be sure theres a problem with your own power supply.

If your power supply light is still unlit, the unit needs to be replaced. You can order a replacement Xbox One power supply unit from our Xbox Online Service Center. Console registration is required to replace the unit under warranty (the power supply warranty is the same as your console warranty).
