Why is my xbox series s controller continuously blinking off and on?

Hi Tolu! My name is Stephanie and I'm more than happy to help you out!

If the other controllers work normally on your console, this means that the error is only on your Xbox series controller.

Please update your Xbox series controller on your Windows PC by following the steps in this article "Update your Xbox Wireless Controller" (https://support.xbox.com/en-US/help...hen select the controller you... . See More.)

"Update your controller on Windows 10/11 by using the Xbox Accessories app:

If you don’t already have the app installed, get it in the Store:

https://www.microsoft.com/p/xbox-accessories/9nblggh30xj3?

Open the Xbox Accessories app.
Connect your Xbox Wireless Controller by using a USB cable or the Xbox Wireless Adapter for Windows.
When the controller is connected, you'll see the message Update Required if an update is mandatory. Install the update.

Important: The Xbox Accessories app is available only on Windows 10/11 and updating the controller over Bluetooth is not supported."

Check if this will resolve the issue.

Kind regards,
Stephanie

Hi Cheebith, I hope you're doing great out there. I am an Independent advisor and I am here to help you in regard to your concern.

Kindly perform a powercycle on your console by following the steps below:

​​​

POWERCYCLE CONSOLE​​​

​​​

1. Turn off your console by holding the Xbox button on the front of the console for approximately 10 seconds. The console will turn off. ​​​

2. Unplug your console for 5 minutes.

3. Turn your console back on by pressing the Xbox button on the console or the Xbox button on your controller. ​​​

Thanks for the reply. Interesting, I did not know that it was "wirelessly" connected while connected to a USB C Data Cord. As soon as I unplug, it stays disconnected (in sync mode the controller also keeps blinking then turns off). If this is right I don't know why I also can't sync any of my other Xbox controllers to the series X unless connected with a cord (works on an One X controller also, stops when unplugged). I don't know why the sync button (blinking) stopped operating all together.

I replaced my batteries and tried to pull and place back in earlier with no luck. I also updated the controller as I set up as new.

The interesting thing is I am able to use the series X controller perfectly on PC wirelessly with windows 10/Xbox PC adapter. I have no problems on PC wireless.

Ok thanks I will try this. I have also noticed when turning the Xbox box series x off, the Xbox button on the unit will continue to blink for up to 5 minutes. I have had to unplug it before to turn it off. I forgot to mention this in my earlier post but now I’m wondering if the two are related. Thanks

But, anyway, why my Xbox series s using this energy saver sleep mode, startup even using my controller?
