wolverine ultimate has power but wont turn on

So i dont know what happened, but my controller dosent wanna work anymore, it blinks twice when i press the power button but it never actually does anything, wont power the xbox, wont flash amything else, im not sure what happened, uve tried to look around a little more but all i saw was videos about just unplugging the xbox for a while then turning it back on (i tried it but nothing really changed) am i doing something wrong? I have trust that it still works i just don't know what it wants
