If you are using an Xbox One S or an Xbox One X please read the following:
- Ensure your Xbox One is switched off
- Unplug the power cord from the console
Important Be sure to wait 10 seconds. This step lets the power supply reset. Make sure you unplug the power supply unit from both the wall and your Xbox One console.
- Wait 10 seconds
- Plug the cord back into the console then press the Xbox button on the front of the console.
- If the console turns on, then the power reset worked.
If you are using an original Xbox One console, please read the following:
- Unplug the cables from the console, wall outlet, and power supply itself
- Wait 10 seconds
- Plug the power cable back into the electrical outlet and the power supply (Do not plug the power unit into the console yet)
- Check the light on the power supply
- If the LED on your power supply unit is on, reconnect the power supply unit to your console
- Check the light on the power supply, if it is blinking then the unit needs to be replaced. If not, then your console should power on normally.
If you're still having trouble with your console you can contact Microsoft directly for support
