Xbox Series X controller won't turn on?

I'm currently trying to close the Xbox controller but this does not work. If I tap the Xbox button once, nothing happens. When I hold the button, it flashes slowly. But if I connect a cable and then turn it on, it works as always. Battery is at 100% and I'm using the controller for the PC.

Did you install the controller driver?

If not, install the Xbox Accessories app. You can also get the driver there

If it still doesn't work, install Driver Booster, which will help solve a lot of PC problems

Was due to the battery, the controller shows 100% but without a cable 0% when I changed the batteries it worked again perfectly
