Note 4 Power button won't work

[Android Central Question]

My N4 power button has started playing up. The other day it wouldn't turn sleep (off button wouldnt work). It ran out and I couldn't turn it on. Managed to eventually after plugging it into a PC and acitvating Download Mode. It keeps doing the same thing, every few minutes or so, the button will just not work! I've had the phone for less than a year. I dropped it back in Februrary and damaged the charging port but that's it. What can I do?
