Xbox One controller won't turn on

When I press the button to turn on, if it’s been sitting for a minute, the light blinks twice then slowly fades away, after that every time I press the button light blinks once and stops, if I hold the button if continues blinking as long as I hold it, my PC is unable to find the device even if I keep holding the button to keep it on. I don’t have the battery pack thing, it uses portable ones and they work fine, they’re brand new, this problem started today out of a sudden, the controller was not dropped or thrown between the last time it worked properly and when it started acting out, or even before that. it was literally out of nowhere, already tried updating the firmware but didn’t change anything at all.
