HELP! My HTC one m7 is not switching on at all the red light doesn't come on when I charge it.

[AC Question]

I have tried to use the technique power button+volume up+down button all three combinations, it doesn't work at all I plug it in and everything (wall charger). I've tried this loads of times btw. I really hope I can fix it because it was in great condition no glitches or anything please help me

Get a new battery perhaps.
